I was taking, or attempting to take a picture of the flaming star nebula Sunday night. After stacking an hours worth of exposures I detected what I assume is about a magnitude 14 to 15 asteroid. Its' position was really close to RA05:19:38 DEC+34:45:58 and was in that area at 05:38 Dec. 7, 09 GMT. It was moving from CE to slightly north of CW at a rate of about 47 arc sec/hour.

Since the object was well defined in the exposures I don't think is was a comet so I would think it was an asteroid.

Any info would be appreciated. Thanks

Most planetarium programs will allow you download current asteroid elements and plot positions based on a time of interest.

Hi Dale,
I think I may have identified your object. Looks like you caught a 19.2 mag asteroid 6798 P-L. At 9UT on the 8th, it is near the center of the location you specified and is moving at about 48 arcsec/hr roughly E to W. Here is the info from the Sky 6 via the MPORB.dat database.
