RE: [APML] OT:Unknown Object

Hi Gary,

Check the Ephemerides available at http://cfa-www.harvard.edu/iau/Ephemerides/ They cover comets and minor planets. Get those and enter them into a computer-based star atlas and you can plot positions for that particular day and time.

I don't know about other resources for checking satellites besides HeavensAbove...you might try getting a rough estimate of which satellites might have been near Pleiades during your exposure time, and then do a web search on that particular satellite to see if you can find an Ephermeride for it.

It's also possible that it was a micrometeorite flashing as it hit the atmosphere, which you wouldn't of course be able to find any data on.

Good luck!

Jason

I took a picture of M45 on 12/28 and when I got the slides back I saw I had captured something else in the image. It's very small, near the middle at the bottom. Is there a resourse where I could possibly find out what this is based on the date and approx. time the picture was taken? I'd just like to find out if for no other reason than to mention it in my picture caption. I've checked "HeavensAbove" and while there were 10 or 12 entries for that date, most did not include RA/DC coordinates. I would appreciate any info anyone in the group can give me. Thanks!

Gary
