TITLE:   GCN GRB OBSERVATION REPORT
NUMBER:  1964
SUBJECT: GRB030324, optical observations
DATE:    03/03/26 21:46:18 GMT
FROM:    Vasilij Rumjantsev at CrAO  <rum@crao.crimea.ua>

V.Rumyantsev (CrAO) and A.Pozanenko (IKI) report:

We have observed the full  error box of  GRB 030324 (HETE Trigger #2641,
Seq_Num: 5) in CrAO with  AT-64  telescope. 10 unfiltered images were
obtained  in March, 24 between (UT) 20:20 and 20:56.
 No afterglow candidate was  found in comparison with DSS2. Using
photometry by A. Henden (GCN 1950) R-band we estimate the limiting magnitudes of
combined images (S/N=3) as following

Start time (UT)       telescope   exposure    limiting mag.
March 24 20:20        AT-64     10x180 s      20.0
