My son, Alex, took the following photographs of the Aurora..
oooo

oooo
They are fabulous. Especially so because as it happened we had mainly cloud cover here in Southern Oregon.
To close, here is an extract from yesterday’s BBC website:
On Thursday night, the stunning colours of the Northern Lights were visible once again even to the naked eye across much of the US.
Experts say the Northern Lights, or Aurora Borealis, are more visible right now due to the sun being at what astronomers call the “maximum” of its 11-year solar cycle.
What this means is that roughly every 11 years, at the peak of this cycle, the sun’s magnetic poles flip, and the sun transitions from sluggish to active and stormy. On Earth, that’d be like if the North and South Poles swapped places every decade.
“At its quietest, the sun is at solar minimum; during solar maximum, the sun blazes with bright flares and solar eruptions,” according to Nasa, the US space agency.
The current 11-year cycle, the 25th since records began in 1755, started in 2019 and is expected to peak next year.
Some of the best evidence for this comes from the behavior of two of the most powerful beings of the Maya world: The first is a creator god whose name is still spoken by millions of people every fall – Huracán, or “Hurricane.” The second is a god of lightning, K’awiil, from the early first millennium C.E.
As a scholar of the Indigenous religions of the Americas, I recognize that these beings, though separated by over 1,000 years, are related and can teach us something about our relationship to the natural world.
Huracán, the ‘Heart of Sky’
Huracán was once a god of the K’iche’, one of the Maya peoples who today live in the southern highlands of Guatemala. He was one of the main characters of the Popol Vuh, a religious text from the 16th century. His name probably originated in the Caribbean, where other cultures used it to describe the destructive power of storms.
The K’iche’ associated Huracán, which means “one leg” in the K’iche’ language, with weather. He was also their primary god of creation and was responsible for all life on earth, including humans.
Because of this, he was sometimes known as U K’ux K’aj, or “Heart of Sky.” In the K’iche’ language, k’ux was not only the heart but also the spark of life, the source of all thought and imagination.
Yet, Huracán was not perfect. He made mistakes and occasionally destroyed his creations. He was also a jealous god who damaged humans so they would not be his equal. In one such episode, he is believed to have clouded their vision, thus preventing them from being able to see the universe as he saw it.
Huracán was one being who existed as three distinct persons: Thunderbolt Huracán, Youngest Thunderbolt and Sudden Thunderbolt. Each of them embodied different types of lightning, ranging from enormous bolts to small or sudden flashes of light.
Despite the fact that he was a god of lightning, there were no strict boundaries between his powers and the powers of other gods. Any of them might wield lightning, or create humanity, or destroy the Earth.
Another storm god
The Popol Vuh implies that gods could mix and match their powers at will, but other religious texts are more explicit. One thousand years before the Popol Vuh was written, there was a different version of Huracán called K’awiil. During the first millennium, people from southern Mexico to western Honduras venerated him as a god of agriculture, lightning and royalty.
Illustrations of K’awiil can be found everywhere on Maya pottery and sculpture. He is almost human in many depictions: He has two arms, two legs and a head. But his forehead is the spark of life – and so it usually has something that produces sparks sticking out of it, such as a flint ax or a flaming torch. And one of his legs does not end in a foot. In its place is a snake with an open mouth, from which another being often emerges.
Indeed, rulers, and even gods, once performed ceremonies to K’awiil in order to try and summon other supernatural beings. As personified lightning, he was believed to create portals to other worlds, through which ancestors and gods might travel.
Representation of power
For the ancient Maya, lightning was raw power. It was basic to all creation and destruction. Because of this, the ancient Maya carved and painted many images of K’awiil. Scribes wrote about him as a kind of energy – as a god with “many faces,” or even as part of a triad similar to Huracán.
He was everywhere in ancient Maya art. But he was also never the focus. As raw power, he was used by others to achieve their ends.
Moreover, Maya artists always had K’awiil doing something or being used to make something happen. They believed that power was something you did, not something you had. Like a bolt of lightning, power was always shifting, always in motion.
An interdependent world
Because of this, the ancient Maya thought that reality was not static but ever-changing. There were no strict boundaries between space and time, the forces of nature or the animate and inanimate worlds.

Everything was malleable and interdependent. Theoretically, anything could become anything else – and everything was potentially a living being. Rulers could ritually turn themselves into gods. Sculptures could be hacked to death. Even natural features such as mountains were believed to be alive.
The illusion is not that different things exist. Rather it is that they exist independent from one another. Huracán, in this sense, damaged himself by damaging his creations.
Hurricane season every year should remind us that human beings are not independent from nature but part of it. And like Hurácan, when we damage nature, we damage ourselves.
The three deer photos show them feeding from me putting out COB (corn, oats, barley) each morning soon after it is light.
Of course, typically the morning I took my camera out there were just four deer. Usually there between seven and fifteen and a couple of months ago a friendly stag in getting to the COB as I was pouring it out rubbed his right antler on my right leg.
I am writing this having listened to a programme on BBC Radio 4. (Was broadcast on Radio 4 on Tuesday, August 13th.) It shows how many, many people can have a really positive response to a dastardly negative occurrence such as the Covid outbreak or a pandemic.
Every Friday, volunteers gather on the Albert Embankment at the River Thames in London to lovingly retouch thousands of red hearts inscribed on a Portland stone wall directly opposite the Houses of Parliament. Each heart is dedicated to a British victim of COVID. It is a deeply social space – a place where the COVID bereaved come together to honour their dead and share memories.
The so-called National Covid Memorial Wall is not, however, officially sanctioned. In fact, ever since activists from COVID-19 Bereaved Families for Justice (CBFFJ) daubed the first hearts on the wall in March 2021 it has been a thorn in the side of the authorities.
Featured in the media whenever there is a new revelation about partygate, the wall is a symbol of the government’s blundering response to the pandemic and an implicit rebuke to former prime minister Boris Johnson and other government staff who breached coronavirus restrictions.
As one writer put it, viewed from parliament the hearts resemble “a reproachful smear of blood”. Little wonder that the only time Johnson visited the wall was under the cover of darkness to avoid the TV cameras. His successor Rishi Sunak has been similarly reluctant to acknowledge the wall or say what might take its place as a more formal memorial to those lost in the pandemic.
Though in April the UK Commission on COVID Commemoration presented Sunak with a report on how the pandemic should be remembered, Sunak has yet to reveal the commission’s recommendations.
Lady Heather Hallett, the former high court judge who chairs the public inquiry into COVID, has attempted to acknowledge the trauma of the bereaved by commissioning a tapestry to capture the experiences of people who “suffered hardship and loss” during the pandemic. Yet such initiatives are no substitute for state-sponsored memorials.
What is remembered and what is forgotten?
This political vacuum is odd when you consider that the United Kingdom, like other countries, engages in many other commemorative activities central to national identity. The fallen of the first world war and other military conflicts are commemorated in a Remembrance Sunday ceremony held every November at the Cenotaph in London, for example.
But while wars lend themselves to compelling moral narratives, it is difficult to locate meaning in the random mutations of a virus. And while wars draw on a familiar repertoire of symbols and rituals, pandemics have few templates.
For instance, despite killing more than 50 million globally, there are virtually no memorials to the 1918-1919 “Spanish” influenza pandemic. Nor does the UK have a memorial to victims of HIV/AIDS. As the memory studies scholar Astrid Erll puts it, pandemics have not been sufficiently “mediated” in collective memory.
As a rule, they do not feature in famous paintings, novels or films or in the oral histories passed down as part of family lore. Nor are they able to draw on familiar cultural materials such as poppies, gun carriages, catafalques and royal salutes. Without such symbols and schemata, Erll argues, we struggle to incorporate pandemics into our collective remembering systems.
This lacuna was brought home to me last September when tens of thousands of Britons flocked to the south bank of the Thames to pay their respects to Britain’s longest serving monarch. By coincidence, the police directed the queue for the late Queen’s lying-in-state in Westminster Hall over Lambeth Bridge and along Albert Embankment.
But few of the people I spoke to in the queue seemed to realise what the hearts signified. It was as if the spectacle of a royal death had eclipsed the suffering of the COVID bereaved, rendering the wall all but invisible.
Waiting for answers
Another place where the pandemic could be embedded in collective memory is at the public inquiry. Opening the preliminary hearing last October into the UK’s resilience and preparedness for a pandemic, Lady Hallett promised to put the estimated 6.8 million Britons mourning the death of a family member or friend to COVID at the heart of the legal process. “I am listening to them; their loss will be recognised,” she said.
But though Lady Hallett has strategically placed photographs of the hearts throughout the inquiry’s offices in Bayswater and has invited the bereaved to relate their experiences to “Every Story Matters”, the hearing room is dominated by ranks of lawyers. And except when a prominent minister or official is called to testify, the proceedings rarely make the news.
This is partly the fault of the inquiry process itself. The hearings are due to last until 2025, with the report on the first stage of the process not expected until the summer of 2024. As Lucy Easthope, an emergency planner and veteran of several disasters, puts it: “one of the most painful frustrations of the inquiry will be temporal. It will simply take too long.”
The inquiry has also been beset by bureaucratic obfuscation, not least by the Cabinet Office which attempted (unsuccessfully in the end) to block the release of WhatsApp messages relating to discussions between ministers and Downing Street officials in the run-up to lockdown.
To the inquiry’s critics, the obvious parallel is with the Grenfell inquiry, which promised to “learn lessons” from the devastating fire that engulfed the west London tower in 2017 but has so far ended up blurring the lines of corporate responsibility and forestalling a political reckoning.
The real work of holding the government to account and making memories takes place every Friday at the wall and the other places where people come together to spontaneously mourn and remember absent loved ones. These are the lives that demand to be “seen”. They are the ghosts that haunt our amnesic political culture.
For most dogs, their friend groups usually consist of a mix of humans and other dogs. But Lili, a 3-year-old dog who lives on a French Polynesian atoll called Fakarava, isn’t like most other dogs. She prefers friends who have gills and fins. In fact, her very best friend is a shark.
Ever since Lili’s mom, Emmanuelle Larchet, adopted Lili, she’s known that her dog has an affinity for all things aquatic. She started swimming in the lagoon near Larchet’s house when she was only a month old.
“She’s really a water dog,” Larchet told The Dodo.
There are around 100 sharks who live in this lagoon near Larchet’s house. So when Lili swims in the water there, she’s surrounded by them. While many dog parents would be terrified to see their dog swimming amongst sharks, Larchet knows that the sharks Lili swims with are nurse sharks, who are actually very docile creatures.
“We call them sea puppies because [they’re] like dogs, actually … They are very nice,” Larchet said.
Larchet likes to joke that when Lili swims around with her shark friends, it’s sea puppies meeting earth puppies.
Over the years Lili has been swimming in the lagoon, there’s one shark in particular she’s grown especially close with. His name is Sharky, and he and Lili visit each other almost every day. Larchet and Lili are able to recognize Sharky because he has a special marking on one of his fins.
Lili and Sharky like to explore their lagoon together. They enjoy splashing around in the warm, clear water.
“He comes to say hello every time she sees him,” Larchet said.
Even though Lili and Larchet are best friends themselves, Larchet is more than happy to share her Lili with Sharky. And even though Larchet watches Lili hang out with her shark friends all the time, it never gets old seeing them spend time together.
“[When] I see her swimming with Sharky, [I’m] so happy,” Larchet said.
As I said to Jeannie the broadcast really spoke to me as each morning I am in awe of the black-tailed deer that I go down to feed near the old stables just outside the house.
Then I pause on my way back and look at Mount Sexton and the rising sun; again I am in awe.
Then at night, being a crystal-clear sky on many occasions, I am in awe at the heavens above.
The programme spoke of one being in awe of both the small and the large and I want to close with two of my photographs of me sensing awe in both scales.
Jess has sent me a great collection of dog pictures that she has found on Instagram and elsewhere and for a few weeks I am going to be sharing them with you.
Yeah, Babe Ruth was one of the most famous baseball players. I love old historical photos and happen to run into that one and thought I’d share. I’m happy that you enjoy my contributions. Have a wonderful day. It’s another hot one here! Jess
oooo
oooo
This is a very touching photo. Dogs grieve about loss just as we do. Jess

So it may seem a little strange that I now publish the following. It was published originally on Skeptic. It is quite a long video but, please, settle down and watch it.

Sean Carroll is creating a profoundly new approach to sharing physics with a broad audience, one that goes beyond analogies to show how physicists really think. He cuts to the bare mathematical essence of our most profound theories, explaining every step in a uniquely accessible way.
Quantum field theory is how modern physics describes nature at its most profound level. Starting with the basics of quantum mechanics itself, Sean Carroll explains measurement and entanglement before explaining how the world is really made of fields. You will finally understand why matter is solid, why there is antimatter, where the sizes of atoms come from, and why the predictions of quantum field theory are so spectacularly successful. Fundamental ideas like spin, symmetry, Feynman diagrams, and the Higgs mechanism are explained for real, not just through amusing stories. Beyond Newton, beyond Einstein, and all the intuitive notions that have guided homo sapiens for millennia, this book is a journey to a once unimaginable truth about what our universe is.
Sean Carroll is Homewood Professor of Natural Philosophy at Johns Hopkins University, and Fractal Faculty at the Santa Fe Institute. He is host of the Mindscape podcast, and author of From Eternity to Here, The Particle at the End of the Universe, The Big Picture, and Something Deeply Hidden. He has been awarded prizes and fellowships by the National Science Foundation, NASA, the American Institute of Physics, the Royal Society of London, and many others. He lives in Baltimore with his wife, writer Jennifer Ouellette. His new book series, The Biggest Ideas in the Universe, includes one volume on Space, Time, and Motion, and this new volume on Quanta and Fields.

I’m assuming you have watched the video because in a world that is pre-occupied with the trivial this is just the opposite. Sean shares his physics in a profoundly different and powerful way!
EVENT: A coronal mass ejection (CME) is an eruption of solar material. When they arrive at Earth, a geomagnetic storm can result. Watches at this level are very rare. TIMING: Several CMEs are anticipated to merge and arrive at Earth on May 12th. EFFECTS: The general public should visit our webpage to keep properly informed. The aurora mav become visible over much of the northern half of the country, and maybe as far south as Alabama to northern California.
Meanwhile, Earth.com presented the following (and it is a long but extremely interesting report):
Update: New solar flare, secondary peak today in this “Extreme” solar storm
The Sun released another powerful burst of energy today, known as a solar flare, reaching its peak intensity at 12:26 p.m. Eastern Time. The flare originated from a region on the Sun’s surface called sunspot Region 3664, which has been quite active lately.
NASA’s Solar Dynamics Observatory, a spacecraft that keeps a constant eye on our nearest star, was able to capture a striking image of this latest solar outburst.
Solar flares are immense explosions on the Sun that send energy, light and high speed particles into space. They occur when the magnetic fields in and around the Sun reconnect, releasing huge amounts of stored magnetic energy. Flares are our solar system’s most powerful explosive events.
The NOAA’s Space Weather Prediction Center (SWPC) has extended the Geomagnetic Storm Warning until the afternoon of May 13, 2024.
Understanding different classes of solar flares
Today’s flare was classified as an X1.0 flare. Solar flares are categorized into classes based on their strength, with X-class flares being the most intense. The number provides additional information about the flare’s strength within that class. An X1 flare is ten times more powerful than an M1 flare.
These energetic solar eruptions can significantly impact Earth’s upper atmosphere and near-Earth space environment. Strong flares can disrupt high-frequency radio communications and GPS navigation signals. The particle radiation and X-rays from flares can also pose potential risks to astronauts in space.
Additionally, the magnetic disturbances from flares, if particularly strong, have the ability to affect electric power grids on Earth, sometimes causing long-lasting blackouts.
However, power grid problems are more commonly caused by coronal mass ejections (CMEs), another type of powerful solar eruption often associated with strong flares.
Scientists are always on alert, monitoring the Sun for these explosive events so that any potential impacts can be anticipated and prepared for. NASA’s Solar Dynamics Observatory, along with several other spacecraft, help provide this early warning system.
Stay tuned to Earth.com and the Space Weather Prediction Center (SWPC) for updates.
Update — May 12, 2024 at 9:41 AM EDT
The ongoing geomagnetic storm is expected to intensify later today, Sunday, May 12, 2024. Several intense Coronal Mass Ejections (CMEs), traveling from the Sun at speeds up to 1,200 miles per second, are anticipated to reach the Earth’s outer atmosphere by late afternoon.
Over the past two days, preliminary reports have surfaced regarding power grid irregularities, degradation of high-frequency communications, GPS outages, and satellite navigation issues. These disruptions are likely to persist as the geomagnetic storm strengthens.
Auroras visible across the continental United States
Weather permitting, auroras will be visible again tonight over most of the continental United States. This spectacular display of lights is a direct result of the ongoing geomagnetic storm.
The threat of additional strong solar flares and CMEs, which ultimately result in spectacular aurora displays, will persist until the large and magnetically complex sunspot cluster, NOAA Region 3664, rotates out of view of the Earth. This is expected to occur by Tuesday, May 14, 2024.
Solar activity remains at moderate to high levels
Solar activity has been at moderate levels over the past 24 hours. Region 3664 produced an M8.8/2b flare, the strongest of the period, on May 11 at 15:25 UTC. A CME signature was observed, but an Earth-directed component is not suspected.
Solar activity is expected to remain at high levels from May 12-14, with M-class and X-class flares anticipated, primarily due to the flare potential of Region 3664.
Energetic particle flux and solar wind enhancements
The greater than 10 MeV proton flux reached minor to moderate storm levels on May 10. Additional proton enhancements are likely on May 13-14 due to the flare potential and location of Region 3664.
The solar wind environment has been strongly enhanced due to continued CME activity. Solar wind speeds reached a peak of around 620 miles/second on May 12 at 00:55 UTC.
A strongly enhanced solar wind environment and continued CME influences are expected to persist on May 12-13, and begin to wane by May 14.
Geomagnetic field reaches G4 “Severe” storm levels
The geomagnetic field reached G4 (Severe) geomagnetic storm levels in the past 24 hours due to continued CME activity.
Periods of G3 (Strong) geomagnetic storms are likely, with isolated G4 levels possible, on May 12. Periods of G1-G3 (Minor-Strong) storming are likely on May 13, and periods of G1 (Minor) storms are likely on May 14.
Stay informed and enjoy the light show
As the geomagnetic storm rages on, we must remain vigilant and prepared for the potential consequences. Monitor official sources for updates on the storm’s progress and any further disruptions to our technological infrastructure.
Take a moment to step outside tonight and marvel at the incredible auroras painting the night sky — a stunning reminder of the raw power and beauty of our Sun.
While these solar storms can cause temporary inconveniences, they also provide us with an opportunity to reflect on our place in the universe and the awe-inspiring forces that shape our world.
Stay tuned to Earth.com and the Space Weather Prediction Center (SWPC) for updates.
Understanding geomagnetic solar storms
Geomagnetic storms are disturbances in the Earth’s magnetic field caused by the interaction between the solar wind and the planet’s magnetosphere. These storms can have significant impacts on technology, infrastructure, and even human health.
Causes of geomagnetic storms
Geomagnetic storms typically originate from the Sun. They are caused by two main phenomena:
Coronal Mass Ejections (CMEs): Massive bursts of plasma and magnetic fields ejected from the Sun’s surface.
Solar Flares: Intense eruptions of electromagnetic radiation from the Sun’s surface.
When these events occur, they send charged particles streaming towards Earth at high speeds, which can take anywhere from one to five days to reach our planet.
Effects on Earth’s magnetic field
As the charged particles from CMEs and solar flares reach Earth, they interact with the planet’s magnetic field. This interaction causes the magnetic field lines to become distorted and compressed, leading to fluctuations in the strength and direction of the magnetic field.
Impacts on technology and infrastructure
Geomagnetic storms can have significant impacts on various aspects of modern technology and infrastructure:
Power Grids: Strong geomagnetic storms can induce currents in power lines, causing transformers to overheat and potentially leading to widespread power outages.
Satellite Communications: Charged particles can damage satellite electronics and disrupt communication signals.
GPS and Navigation Systems: Geomagnetic disturbances can interfere with the accuracy of GPS and other navigation systems.
Radio Communications: Storms can disrupt radio signals, affecting communication systems that rely on HF, VHF, and UHF bands.
As charged particles collide with Earth’s upper atmosphere, they excite oxygen and nitrogen atoms, causing them to emit light in various colors.
Monitoring and forecasting
Scientists continuously monitor the Sun’s activity and use various instruments to detect and measure CMEs and solar flares.
This data helps them forecast the timing and intensity of geomagnetic storms, allowing for better preparedness and mitigation of potential impacts.
Historical geomagnetic storms
Some of the most notable geomagnetic storms in history include:
The Carrington Event (1859): The most powerful geomagnetic storm on record, which caused widespread telegraph system failures and auroras visible as far south as the Caribbean.
The Halloween Storms (2003): A series of powerful geomagnetic storms that caused power outages in Sweden and damaged transformers in South Africa.
The Quebec Blackout (1989): A geomagnetic storm that caused a massive power outage affecting millions of people in Quebec, Canada.
Understanding geomagnetic storms is crucial for protecting our technology-dependent world and mitigating the potential risks associated with these powerful space weather events.
