GCN Circular 2850
A. Henden (USRA/USNO) and F. Vrba (USNO) report on behalf of the USNO GRB team: We have acquired shallow BV all-sky photometry for a 11x11 arcmin field centered on the coordinates for the optical transient discovered by Christensen (IAUC 8452) and mentioned in the report by Christensen (GCN 2849) with the USNOFS 1.0-m telescope on one photometric night. Stars brighter than V=12.5 are saturated and should be used with care. We have placed the photometric data on our anonymous ftp site: ftp://ftp.nofs.navy.mil/pub/outgoing/aah/sequences/lynxot.dat The astrometry in this file is based on linear plate solutions with respect to USNOA2. The external errors are less than 300mas. The estimated external photometric error is about 0.02mag. We have also acquired three consecutive nights of unfiltered photometry (similar to wide-band Johnson V) for the object using the 1.0m. Our results are: 041213 21.118 0.054 041214 21.062 0.067 041215 21.098 0.062 In addition, we have 1.55m observations that indicate that this object is stellar in appearance. Our impression is that this is a galactic source of some sort and not an unidentified GRB afterglow.
