GCN Circular 268
BVRI photometry in the field of GRB 990123 was performed with the USNO 1.0-m telescope in Flagstaff during the February dark run. Results of that photometry have been posted at: ftp://ftp.nofs.navy.mil/pub/outgoing/aah/grb/grb990123.dat with a more complete description of the photometric procedures in: ftp://ftp.nofs.navy.mil/pub/outgoing/aah/grb/grb990123.readme Objects 1-18 in the photometry file are numbered identically to Nilakshi, et. al. (GCN 252). Other objects are either fainter stars in the same field, or else brighter stars within the 11x11 arcmin field of the CCD to be used for field identification. We have omitted the obviously extended objects 7, 9, and 16. We note some photometric differences between Nilakshi and this new photometry.
