Partial Lunar Eclipse of September 07

 

Ok Im in Okinawa Japan and NASA web site says that there is going to be eclipse here. But Im not understanding what time of day here in Japan it will be. A local magazine says Sept 8 from 1500 - 1630. but when I look at NASA's website it says

 

Penumbral Eclipse Begins: 16:42:23 UT

Partial Eclipse Begins: 18:05:03 UT

Greatest Eclipse: 18:51:21 UT

Partial Eclipse Ends: 19:37:41 UT

Penumbral Eclipse Ends: 21:00:20 UT

 

 

UT to JST = +9

 

so Sept 7 1842UT = Sept 8 0342 JST

:cup:

its going to start at 3am? going to have eclipse before the sun even comes up? is the magzaine wrong when it stay its going to be at 3pm then?

 

 

The second lunar eclipse of the year is a rather small partial eclipse. The penumbral phase begins at 16:42 UT, 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

Partial Eclipse Begins: 18:05:03 UT

Greatest Eclipse: 18:51:21 UT

Partial Eclipse Ends: 19:37:41 UT

Penumbral Eclipse Ends: 21:00:20 UT

 

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 (18:51 UT), 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. The event is best seen from Africa, Asia, Australia and Eastern Europe. Unfortunately, none of the eclipse is visible from North America. The Moon's path through Earth's shadows as well as a map illustrating worldwide visibility is shown

Try this:

Maximum eclipse at 1851 UT on Sept. 7th

Use the calculator at this site to make your local time adjustment to 1851 UT September 7 2006

going to have eclipse before the sun even comes up?
It isn't necessary for the sun to be up, to the contrary it is necessary for it to be down.

 

Where the sun is up, you wouldn't see the moon anyway because it is in exact opposition. Well, except at sunset or sunrise and if the horizon is quite clean, better if you are at a high altitude.

yeah I understand. I kept thinking solar eclipse but its a lunar one.:cup:

 

anyway I hope the sky is clear and I can get a few shots

here is some of the best pictures I took. The link to the full size are below each image

Very kewl SF!:hihi: I have found that using a digital video camera to photograph the Moon, I have to set to manual exposure & ramp it down in order to see the craters and mare. As some of your photos are washed out and others (the best!) are not, I wonder if you also used manual exposure?

What other techniques did you employ for your photographs? Do you know about the new effort to photograph meteors striking the Moon?

Anyway, nice stuff and A+ for effort and sharing of science.:D

thanks, I was trying to use what little adjustments this camera has. the ones that came out the clearest, I used a pair of sunglasses as a filter to cut down on the glare.

 

Im going to look for a easy to use SLR soon.

 

no I have not heard about trying to take pictures of metors striking the moon.

Here is our Hypography on Moon meteors:

What type of camera do you use now? (If that's not too invasive a question.)? If you have an option to manually set the exposure, turn that on & reduce the exposure. Here is a Moon photo of mine that I took with this technique.

Of course the dumb machine doesn't know that you're only interested in the exposure for that little disk, not the rest of the field which is dark.

 

Back in the late '80s I was in Paris with a guy that was even dumber than his camera's exposimetre. Just after dark this guy saw the Eiffel tower all lit up, against the dark background and he got his camera out, fiddled with the adjustments, saw that the metre told him there was far too little light and put the camera away saying "no use". At that time I had never even owned a camera of my own but I understood the principles. BS, I told him and, with difficulty, persuaded him to let me try, he kept saying that I would only waste a frame and finally said "OK, you'll see" and handed me the thing (and even had to show me the details of how to work it!).

 

;) when he got the film developped after that trip he was amazed and in raptures about the effect of the structure apparently floating in a void.
