TITLE:   GCN GRB OBSERVATION REPORT
NUMBER:  1881
SUBJECT: GRB 030226, optical observations
DATE:    03/02/26 08:28:13 GMT

We have imaged the error circle of the HETE burst GRB 030226
with the 40-inch Swope telescope at Las Campanas beginning
Feb. 26.30  (UT). The R-band images confirm the presence
of a new source (GCN 1879). We derive a position of
RA=11:33:04.92  DEC=+25:53:55.62 (2000) based on stars from
the USNO A-2.0 catalog.  Assuming the USNO star with end figures
of 03.214 51:30.73 has an R mag of 15.0, we estimate the
brightness of the transient at R=18.0.
