Getting too old for this!

This wasn’t what I had planned for today ….

….. but I only managed to get my office back to some form of functionality late yesterday afternoon.

So some peeks into the last few days..

The installers arrived bright and early on Saturday morning.

But I guess one advantage of us starting to get used to the house being upside down, it having been like this since the 11th, was that the dogs were pretty relaxed about the whole affair.

Not quite sure that Jeannie and me were so cool about the chaos that had surrounded us for so many days now.

Then the picture below was the state of my office Sunday afternoon.

But the one great bonus was that the smoke in the air from nearby forest fires meant that yesterday’s sunrise was a very beautiful sight.

Hopefully, good people, back to more normal times tomorrow. (And the new floor does look great!)

Solstice Lunar Eclipse

(Again, thanks to Dan G for highlighting this.)

If you want to see this solar eclipse then read the times carefully – to assist, I am publishing this Post much earlier than normal, at 18:00 US Mountain Time (UTC -7hrs) on Monday, 20th December.  Oh, and more information at Spacedex here.

SOLSTICE LUNAR ECLIPSE

Dec. 17, 2010:  Everyone knows that “the moon on the breast of new-fallen snow gives the luster of mid-day to objects below.”

That is, except during a lunar eclipse.

The luster will be a bit “off” on Dec. 21st, the first day of northern winter, when the full Moon passes almost dead-center through

Earth’s shadow. For 72 minutes of eerie totality, an amber light will play across the snows of North America, throwing landscapes into an unusual state of ruddy shadow.

The eclipse begins on Tuesday morning, Dec. 21st, at 1:33 am EST (Monday, Dec. 20th, at 10:33 pm PST). At that time, Earth’s shadow will appear as a dark-red bite at the edge of the lunar disk. It takes about an hour for the “bite” to expand and swallow the entire Moon. Totality commences at 02:41 am EST (11:41 pm PST) and lasts for 72 minutes.

If you’re planning to dash out for only one quick look — it is December, after all — choose this moment: 03:17 am EST (17 minutes past midnight PST). That’s when the Moon will be in deepest shadow, displaying the most fantastic shades of coppery red.

Why red?

A quick trip to the Moon provides the answer: Imagine yourself standing on a dusty lunar plain looking up at the sky. Overhead hangs Earth, nightside down, completely hiding the sun behind it. The eclipse is underway. You might expect Earth seen in this way to be utterly dark, but it’s not. The rim of the planet is on fire! As you scan your eye around Earth’s circumference, you’re seeing every sunrise and every sunset in the world, all of them, all at once. This incredible light beams into the heart of Earth’s shadow, filling it with a coppery glow and transforming the Moon into a great red orb.

Back on Earth, the shadowed Moon paints newly fallen snow with unfamiliar colors–not much luster, but lots of beauty.

Enjoy the show.

Coincidences (UPDATED): This lunar eclipse falls on the date of the northern winter solstice. How rare is that? Total lunar eclipses in northern winter are fairly common. There have been three of them in the past ten years alone. A lunar eclipse smack-dab on the date of the solstice, however, is unusual. Geoff Chester of the US Naval Observatory inspected a list of eclipses going back 2000 years. “Since Year 1, I can only find one previous instance of an eclipse matching the same calendar date as the solstice, and that is 1638 DEC 21,” says Chester. “Fortunately we won’t have to wait 372 years for the next one…that will be on 2094 DEC 21.
