Partial Eclipse of the Moon 7th Sept

Nick-H · Sep 7th, 2006, 01:04

Supposed to be visible over the next hour or so here in India.

Couldn't see anything, so came inside for a nice crescent-shaped omlette!

Going for another look now...

Hope this makes things clear and the eclipse visible too!!! A partial eclipse is not so attractive or spectacular as a total eclipse so you may not see the subtle changes as it takes place in the penumbral region, only the umbral region gets really dark or eclipsed as normally seen. The penumbral phase is hardly distinguishable from the normal non eclipsed moon!!!

Cheers,
Aadil.

That makes it look as if it will be rather disapointing. I've seen partial lunar eclipses that I hadn't heard about before the event that stopped me in my tracks and made me wonder what I might have swallowed: like crescent moons, but entirely the "wrong" way up.

First of all it is not really as spectacular an event as the total eclipse. I have seen many of these penumbral ones and they usually cannot be made out unless you are really a keen observer who can make out the differences in the subtle changes in brightness of the moon during eclipse. These things are given undue importance according to Indian astrological factors which I do not believe in!!!

Cheers,

Not worth getting bitten for, really.

Only result was getting some moon pics, which I've never really tried to do before.

Not bad for a hand-held first attempt...

aadil · Sep 7th, 2006, 03:06

WOW!!! That is a pretty good picture of the moon!!! Thanks for sharing on IM and I am pretty sure you will see many more eclipses if you were interested in astronomy like me!!!

Cheers,

Credit goes to the Canon S2 IS, and particularly its image stabilisation --- though I had to use manual settings to avoid getting a blank white circle.

Isn't digital wonderful: I'd have wasted most of a roll on the failures!

aadil · Sep 7th, 2006, 04:04

Well, I don't think you would have got anything on a SLR if you did not have the proper zoom lenses on it as well as a tripod to take a stabilized time exposure for a good picture and still it might not have come out this good!!!

Cheers,
Aadil.

That is a good photo. I just looked up the model and am surprised that such a camera with a 12x zoom could take such a photo. I was expecting some huge lens!

robotvoice · Sep 7th, 2006, 11:07

i concur, looks as professional as any i've seen. now i wanna go see what my carmera can do.

Great photo!

No eclipse where I am (Northern California), as aadil's map shows. BUT, the moon was particularly gorgeous tonight anyway. Completely full and very low in the sky when I was leaving my office, so it looked HUGE ... until I drove into the usual summer fog bank that comes in the Golden Gate and heads STRAIGHT FOR MY HOUSE ... after that, no more moon, eclipse or no eclipse ...

Nick-H · Sep 7th, 2006, 14:37

Amazing compliments for the photo! Thanks

Quite makes up for spending an hour getting bitten (despite the Odomos) out on the roof

It really was almost point-and-shoot.

The camera has a good zoom lens, goes to about 400mm [35mm equivalent]. And that is Optical zoom. In fact it is also good for macro work right up to the lens surface! So I can get some reasonable pics of insects.

It was not a long exposure, either: I think it was 1/1000 at F4.5, though the camera told me "+2" which I guess means it was maybe 1/500 at F3.5 or something (I'll have to check the book to see what it was saying). Also I set the metering to spot. In the viewfinder the moon didn't even fill the metering/focussing rectangle!

Nick-H · Sep 7th, 2006, 16:09

But WAIT!

Both Mrs N (unusually) and I (no surprise) misread the info in the paper.

It's TONIGHT!

Oh well, what a waste of mossie bites

I thought so too after all the date mentioned everywhere was the 7th so I was wondering why you were doing it one day in advance, but then I usually do the same thing just to get the hang of it a day before and to get the settings right for good pictures!!! Actually I did not have the heart to tell you that it was not an eclipsed moon that you took a picture of and hence if you notice I just mentioned that it is a good picture of the moon (and not eclipse!!!). So are you out tonight too with the mossies and the moon in eclipse?!!!

Cheers,
Aadil.

This second lunar eclipse of the year is a rather small partial eclipse. The penumbral phase begins at 10:12 IST, but most observers will not be able to visually detect the faint shadow until about 17:30 UT. A timetable for the major phases of the eclipse is as follows: Penumbral Eclipse Begins: 16:42:23 UT (10:12:23 pm IST)
Partial Eclipse Begins: 18:05:03 UT (11:35:03 pm IST)
Greatest Eclipse: 18:51:21 UT (12:21:21 am IST)
Partial Eclipse Ends: 19:37:41 UT (01:07:41 am IST)
Penumbral Eclipse Ends: 21:00:20 UT (02:30:20 am IST)

In spite of the fact that the eclipse is shallow (the Moon's northern limb dips just 6.3 arc-minutes into Earth's dark umbral shadow), the partial phase lasts over 1 1/2 hours. This is due to the grazing geometry of the Moon and umbra.
At the instant of greatest eclipse (12:21 IST), the Moon will stand near the zenith for observers in the central Indian Ocean. At that time, the umbral eclipse magnitude will be 0.190.

Area of visibility: The eclipse is visible from the parts of Antarctica, Australasia, Asia, Africa, Europe including the British Isles.
The beginning of the umbral phase visible in New Zealand, Middle of the Pacific Ocean, Eastern Part of Australia, Eastern parts of Japan and North-eastern parts of Russia. The ending visible in North-Western parts of Africa, Western parts of Europe, Ireland and middle of the Atlantic Ocean. The event is best seen from Africa, Asia, Australia and Eastern Europe. This eclipse is not seen from the USA.
