As there was a clear night tonight and a more interesting moon (not the glare of a full moon), the reasonably new 100-400 was mounted on the tripod and pointed in it's direction:

Of course, with digital, you don't just take one image - sorting through the few I took (at different settings), I noticed a dark spot on the southern edge:

Close inspection reveals what I belive to be a shadow of a passing satelite:

(bugger, just realised I have photobucket set to resize to 640x480 - for another fourm I participate in).

I've looked at Stellarium but have been unable to determine which satelite it might have been (Select Birmingham, United Kingdom 2012-02-29 at 19:36:06 if you wish to investigate). That time is correct as my camera's clock was 1m28s fast - it's now been corrected.

the later images are clear of the shadow (illiminating a mark on the lens)

Interesting.

Cool catch, and good job noticing it! Looks a little like the ISS.

You may be looking directly at the satelite. Definitely and "I Spy" moment. LOL!


just a few of my thoughts...

Undoubtedly you have never taken and image of the moon through a scope have you ? You wont get a bird image like that with that kind of a closeup of the moon muchless through a scope ... :rolleyes: .

It looks a little small for ISS and the wrong shape. I don't want to post someone else's picture but look here:

And you can find lots of others. I'm going with a bird.

Actually I have done some high resolution shots of lunar craters before, here's one

I thought it was a bird just becuase I have visually observed such small shandow on the moon several times in the past(high power observing). but correct me if I was wrong.;)

There is plenty of space junk and hardware floating around that can cast a shadow, or be silhouetted against the moon. I think you caught one.

Coincidentally, it could also be a Cygnus, or Whooper Swan, which have been seen at almost 30,000 feet.

According to Heavens Above the best candidates are (in terms of time) Envisat - passed over Birmingham between 19:34 & 19:37, but to the north so in the wrong direction I think, and Tiangong 1 - passed over Birmingham between 19:29 & 19:32 in the south. These are the times for visible observation so I guess by the time Tiangong 1 passed into the Earth's shadow it may have been in the right position to cross the Moon although it's track looks to be too low in the horizon to me (below 15 degrees elevation).

I'm not sure if large military satellites' details are published on the net (X-37B is on Heavens Above) so it could be one of those I suppose. It would be interesting to work out roughtly where in the sky this was based on the Moon's position at the time and the rough dimesnions of it (it looks a bit of a beast).

Thanks for the favourable comments and an interesting discussion.

As for the; is it a bird, is it a plane, I'll settle for an UOO (Un-identified Orbiting Object ;))

The link to the guys that strive to capture a passing satelite was interesting, although I'll just put mine down to luck - I think I'll buy a lottery ticket this weekend.

Regards
Lawrence

Just to be pedantic, it's a silhouette not a shadow.

I have, thousands of times, and it's a bird.
