GRAS & MPChecker

[Atlantia]

Hi,
I've been playing around with GRAS recently, and I've taken some images with asteroids in them which I'd like to identify. I took two images with the same co-ordinates (NGC 7399) over two consecutive nights, and then searched for variations between the two images. I've found half a dozen, so I 've used the Minor Planets Checker to try and identify them. Although, I'm having a bit of difficulty trying to match them up. I'm unsure off the orientation of the image, therefore identification is hard with the offsets given.

One of the images is attatched, with one of the potential asteroids...
The FOV is 37 arc minutes wide.

MP from MPChecker: (with search results of
RA: 22h 52m 41.9s DEC: -09° 16' 01" - 2010-10-1 UTC; 15 arc minute radius)

1998 SB144 RA 22 52 36.0; DEC -09 11 51; V 18; Offsets 1.4W 4.2N
2002 UV34 RA 22 52 58.4; DEC -09 22 40; V 19.9; Offsets 4.1E 6.6S
2010 PB10 RA 22 53 01.7; DEC -09 07 09;V 19.1; Offsets 4.9E 8.9N
1999 TD264 RA 22 53 16.3; DEC -09 07 51; V 19.9; Offsets 8.5E 8.2N
2005 SY178 RA 22 52 26.8; DEC -09 30 26; V 19.8; Offsets 3.7W 14.4S

The image is attatched, with one of the asteroids in the bottom left quadrant - its marked! Is someone able to tell me, from the information above, which one it is likely to be (also, the image was taken in New Mexico, USA) ?

Thanks, I'd appreciate any help!

Kate :)

You can always use Aladin and the DSS database to compare images. Here your image is N down and E to the right.

Eyeballing it in Aladin puts the target at 22 52 -09 12 so;
1998 SB144 RA 22 52 36.0; DEC -09 11 51; V 18; Offsets 1.4W 4.2N

appears to be the closest target. Why not get hold of Astrometrica (its very cheap and has a fully functional trial version) to load your image in and autoplatesolve and it will plot known targets as an overlay.

Cheers

This is what Unimap thinks of it. I had to invert the image.

Alright then, thankyou both for your trouble. :)
