TITLE: GCN GRB OBSERVATION REPORT
NUMBER: 1974
SUBJECT: GRB 030328: Optical afterglow candidate
DATE: 03/03/28 13:53:06 GMT
FROM: Paul Price at RSAA, ANU <pap@mso.anu.edu.au>
B.A. Peterson and P.A. Price (RSAA, ANU) report:
We have observed the error box of GRB 030328 (HETE #2650) with the SSO
40-inch telescope + WFI in B and R filters at Mar 28 12:37 UT. We
identify a source not present on the DSS 2 red plate. The coordinates of
this source are:
RA: 12:10:48.4 Dec: -9:20:51.3 (J2000)
with an error of 0.4 arcsec in each coordinate. At this stage, we
estimate that the afterglow candidate is roughly 18th magnitude.
Further observations are planned, and a finding chart will follow.
