I understand that the eclipse will be a tad redder than normal because of the dust tossed into the atmosphere from Mount Saint Helens and a volcano which has done its thing in Mexico.

Can this be true? I live around 7-8 degrees basically north of MSH and as far as what I saw there was not a heck of a lot of dust blown off. I never heard of the Mexican Volcano.

If you want to get online and share your experiences, Kelly Beatty from Sky & Telescope is hosting an online chat on Wednesday. Here are the details:

Join skywatchers from around the world in the Chat Room of Compuserve's Astronomy Forum on Wednesday night, Oct. 27th, to talk about the total lunar eclipse as it's happening (it's a real-time exchange -- no time lag!!). This'll be a great chance to describe what you're seeing and to learn how it looks to others. These kinds of visual observations can actually be valuable for post-eclipse analyses.

Tentatively, the chat will start at 10 p.m. EDT (7 p.m. PDT) -- the moderator might be there a few minutes earlier or later, depending on how the weather at his observing site and on how the Red Sox are doing in Game 4.

To get to the Astronomy Forum, go to http://community.compuserve.com/astronomy. To join the chat you'll need to login with an AOL, CompuServe, or AIM account. Use the login button at upper right on the Forum's home page. (AIM accounts are free.)

For times and other background info on the eclipse, see the messages posted in the Astronomy Forum or go to the observing section of SkyandTelescope.com

No more total lunar eclipses. There'll be two partials and two penumbral eclipses in the meantime. But it doesn't look like they'll be anything worth staying up for.

In the UK we are a bit ahead of you guys (5-7 hours) so we see it early morning on the 28th. At the moment some partial cloud but not too serious so it looks as if I'll stay up. The total earlier in the year was a washout with wall to wall cloud.

I've got a completish list of astrocameras that will be broadcasting the eclipse here:

http://www.universetoday.com/html/special/le-oct04.html

So, if you're rained out, or you live in a part of the world that can't see it, at least you can check it out on the Internet.

If you're going to broadcast it, drop me an email at info@universetoday.com

Good luck.

It will be interesting to hear what folks say about the eclipse as it relates to the ball game tonite.

Here is just one...


David Huestis, Northern Rhode Island’s resident astronomer, reported Tuesday that the weather looks good for both Sox fans here and their team in St. Louis to see a rare full lunar eclipse.

Not only should the skies be clear for its viewing in both New England and St. Louis, but Huestis reported that tonight will also be the first time an eclipse is believed to have occurred during an actual World Series game.

Yeah, but I have to agree with Neil deGrasse Tyson's comments on cnn this am. The press calls it a "rare" total lunar eclipse (there's been 4 in the past 2 years). First total lunar eclipse during a World Series game, yup, they only started playing night games in the World Series in 1971(?). I will admit the comments could be interesting during the game, but I'll be outside viewing and snapping some pics (if the clouds clear).

You're right. Not so rare...

From Space.com... here (http://www.space.com/spacewatch/041001_lunar_eclipse.html)


Interestingly, this will be fourth total lunar eclipse dating back to May 15, 2003. Four successive lunar eclipses can all be total ones, each eclipse coming at intervals of just under six months apart. Such an unusual lunar cycle is called a tetrad.

The Italian astronomer Giovanni Schiaparelli (1835-1910) discovered that during a period of about three centuries tetrads can occur rather frequently; then in the next three hundred years tetrads never occur at all.

About 15 minutes ago the Moon was behind a bank of altocumulus.

But now the clouds have moved off and the entire sky is clear. The penumbral shadow is very obvious now.

In Eastern Scotland, rather than blanket cloud cover we have more like carpet cloud cover - complete with underfelt! :(

The odd thing is it's pretty windy with little in the way of rain. Usually that kind of weather affords very clear patches and breaks in the cloud. Not tonight though.

I think someone has their doomsday weather machine on turbo :lol:

It has been clear weather all day here in Gothenburg, Sweden, but during the night there has been thin clouds, or sort of "hazy" sky + awfully lot of light pullotion as usual :evil:.

The totality started here at 4:23 am local time, but I'm not sure it was worth staying up for; the moon is currently very dim, and if I didn't know that it is supposed to be reddish I wouldn't have noticed :cry:.

I'm off to bed...

It's just perfect here in upstate NY. I've taken about 120 images so far, I keep coming in every 30 minutes to dump them to the hard drive. It's a gorgeous eclipse, I can't say enough.

Just a few random, small high clouds (not one in front of the moon so far), excellent seeing, and it's even warm for late October. I'll send up a collage of images later tonight after the complete eclipse is over, and I start to pick and choose which images to use.

And Grant, if you're watching, the moon is right where it's supposed to be, eclipse right on time. Back out for totality (by the way, great star hopping now that the moon is so faint, I'd guess an increse of at least two in LVM, without actually checking.

It looks pretty darn cool. The top still has a faint whiteness to it and the bottom right seems to dissapear. Overal it is reddish. Too dim for my junker camerea to really pick up, but I took a few pics. Now if I can find my usb cable, I will trot them out.

Evan
2004-Oct-28, 03:46 AM
Clouds rolled in but not before I got a few pics. I'm still figuring out the 300mm lens on my Rebel and this is slightly out of focus. That of course is likely due to my failing eyeballs more than the camera. It is also somewhat grainy due to being shot at ISO 3200. Looks like Mars.

Well, not only did we have heavy cloud cover for the duration of the eclipse, but I looked outside about a half hour ago and it was clearing up - and I could see the moon shining brightly, without a single cloud anywhere near it. SO frustrating. #-o :evil:

Thanks to those of you who have been giving reports and/or posting pictures - keep them coming! =D> I'll have to enjoy the eclipse vicariously (and posthumously :wink: ) through you guys.

I didn't know about this event, and this morning when I walked to my car, I noticed the moon and the fact that about 3/4 of it was bright. So I thought that it was the current phase of the moon. Then I realised that the dark side was pointing to very strange direction, certainly not away from the sun. "Clouds", I thought. But then it didn't seem like clouds either. It was somewhat dark, but not dark enough for me to deduce that there seemed to be no clouds in the direction of the moon. It didn't make sense to me that there should only be one cloud in the sky and it would be so precisely over the moon with such well defined lines. So then it hit me. I was witnessing partial eclipse of the moon!!!

And then I see this thread in BABB about total eclipse of the moon and it makes me curse my decision in this morning that I want to sleep half an hour longer than I normally do. I could have had a nice show during my boring half an hour drive to work.

Well ... I got a partial view of this total eclipse. I wasn't cursed with the total cloud cover that others in this thread have complained about, but my area did have a lot of thin, hazy clouds that made the view of the moon kinda fuzzy, like staring at it through one of those Vaseline-smeared lenses they use for "hazy" scenes in the movies.

When the eclipse was starting, there were patches of small thick clouds passing in front of portions of the moon, so I couldn't be sure if what I was seeing was lunar eclipse or cloud cover!


Personally, I liked the previous lunar eclipse better. Where I live, there was no cloud cover at the time, and the moon rose already fully eclipsed. It looked like the Death Star had parked itself in orbit around the Earth.

We had similar conditions here in Colorado. Even when the thin clouds cleared, the moon was still some-what hazy. The eclipse seemed much darker this time even taking the clouds into account. It still was pretty neat.

Interesting. I thought I saw a little "brick red" putting it a little over 2, I suppose.

I am curious if Europe (or a little further east) saw it a little redder due to it's low elevation. Maybe there would be no difference, if there is no shorter wavelengths left to scatter as it comes back through the atmosphere.

It's usually cloudy where I live, but last night was absolutely gorgeous! Not just the eclipse itself, but the beautiful stars that were visible at the time of the moon's phases when they usually don't show as well. Red moon and bright stars. Lovely combination!

I got some great viewing here in Fairfax Virginia for the first hour plus of the eclipse. Even got to stay on the porch for most of it before the moon rose above the crest of the roof and I had to go down to the street.

Clouds rolled in shortly after totallity so I quit after twenty minutes of get little peaks every few minutes, but overall it was great. Couple of neighbors came down and took a look through my telescope as totallity approached... thought that was neat.

Wish I had thought to take some picture like some of you. :oops: I even have a really great camera for it... grrrrr. Thanks for the pics from those that thought ahead... awesome!

Clouds broke in time to view totality. Then they danced around it and the moon peeked out for long periods from behind them. so I could watch it emerge from shadow. A little redder than I anticipated. But I just think I didn't anticipate it being very red.

The one thing that finally hit me after sitting in the dark during totality was how dark it was around me. I live in a fairly dark location away from immediate lights. When the full moon is up, it is one big bright light illuminating everything. But last night I was sitting out looking up at a full moon and I couldn't see 5 feet in front of my face.

Kind of cool. Glad the clouds parted and gave me a view.

The average length of the Earth's umbra is 1,400,000 km. At the mean distance to the moon the umbra is approximately 9400 km in diameter. As the Earth subtends 2° as seen from the moon and has a diameter of 12,760 km then the angular diameter of the umbra as seen from Earth (if projected on a rather large screen) would be about 1.5°, roughly three times the diameter of the Moon.

It will be interesting to hear what folks say about the eclipse as it relates to the ball game tonite.

Here is just one...


David Huestis, Northern Rhode Island’s resident astronomer, reported Tuesday that the weather looks good for both Sox fans here and their team in St. Louis to see a rare full lunar eclipse.

Not only should the skies be clear for its viewing in both New England and St. Louis, but Huestis reported that tonight will also be the first time an eclipse is believed to have occurred during an actual World Series game.

[Edit: I did not find a Northern Rhode Island U., so, does your state have it's own regional resident astronomer? :) ]

I didn't realize Rhode Island was big enough to have regions.

Since the moon is moving how slow of a shutter speed can you shoot before you get motion blur?

That depends on the focal length. For 50mm about 20 seconds. For 400mm about 5 seconds with no tracking.

I have been taught that 600 divided by the focal length of the lens gives you the maximum exposure time, in seconds.

That is a pretty good rule of thumb. I base my answer on practical experience. If it really matters I put my camera on my double arm drive which is accurate to around one arc second over two hours.

In picture four there are two rogue planets behind the moon must by planets Y and Z 8-[ .

Pff, turn your brightness down. :P

I had to crudely remove (conceal?) a couple of artifacts.

Thanks. :D I estimated that it was somewhere close to 2 degrees by mentally projecting the rest of the shadow based on what curvature I could see.

It will vary from 2.5 to 3 degrees depending on when the eclipse occurs. Good guess.
