With my current luck, the drought will break the night before...
(I'll be watching, 'though.)

Just a FYI.

Don't forget to be prepared for a total eclipse of the Moon at 17:44
EST on Saturday, 3/3. There hasn't been a full eclipse visible in
North America since 10/2004, so be prepared.

Unfortunately, us West Coasters aren't going to be so fortunate as to
get a full eclipse -

sniff

My heart bleeds. :-(
(All the way from Sydney, Australia)

...but thanks for the heads-up.

Hey, after the spectacular performance the comet put on for you down
there, you're not getting any sympathy on astronomical opportunities from
*me* for a while!!

hehe
There's gotta be *some* compensation for not having a half-decent pole star.

Just go into a dark closet and take a shot without flash... ;-)

It's pretty cool actually, the moon turns red when it's in full eclipse.
I don't know why.

Oh, I don't think so. We never were particularly hot on standards or
uniformity.

Please read the rest of this posting to the tune of "Rule Brittania" or
"Land of Hope and Glory"...

I think the UK (or specifically England) has a reasonable claim to being the
origin of the English language and I get unaccountably upset to see
perfectly good English words fall into disuse and others getting misused in
their place.


Snip

However, my ancestors have been speaking English as long as yours,
since at some point they are the same. I therefore claim the English
language as my own and shall do with it what I feel fit. (Said in
jest, not intending to start an international incident.)

I suspect that it is light bent around the earth through its
atmosphere.

Isn't it just because the moon is being illuminated by light leaking around
the edges of the Earth, just like a nice sunset?

That happens when it's a total eclipse of the heart.

I thought of that too, but took Archie's advice several times and
stifled myself.

Oh, I've -seen one; I'm just imagining what I'd get if I tried to
photograph one.

Here is an example:
http://www.clarkvision.com/galleries...0.67x-872.html
ISO 200, lens was a 700 mm focal length at f/8
(Canon's 500 mm f/4 IS L telephoto lens plus a 1.4x teleconverter).
Exposu 4 seconds.

A totally eclipsed moon is usually pretty dark, so the exposure
times can get long. The more central the moon moved through
the shadow, the darker it usually is. The problem is that
the earth is rotating, so the image will be smeared at long
focal lengths. The above image has a scale of 3.1 arc-seconds
per pixel, and the earth's rotation moves the image about
15 arc-seconds per second of time, so exposures longer than
about 1/10 second in the 700 mm focal length will show motion
blur. The above image was obtained on an equatorial tracking mount.

Yes, but it is not leaking light. The light is refracted through the
Earth's atmosphere. How red the eclipse appears depends on the
dust in the earth's atmosphere. Just like dust in the atmosphere
can make sunsets redder, it can make a lunar eclipse redder.
