V.Rumyantsev (CrAO), V.Biryukov(SAI) and A.Pozanenko (IKI) report:
We have obtained 44 unfiltered exposures (120-s each) of the GRB 030228
error box (HETE Trigger #2650). The images were taken with the AT-64
telescope of Crimean Astrophysical observatory and cover the period
(UT) 18:46 - 23:07 March 28, 2003. We used CCD SBIG ST-8 with
maximum of sensitivity in the red spectral band.
In a co-added image the OT is visible at the position of reported by B.A.
Peterson and P.A. Price (GCN 1974). The brightness was estimated in
respect to the star B (GCN 1982) as R = 20.9 +/- 0.2.
Start time exposure OT
March 28 18:46 44x120 s 20.9 +- 0.2
Detailed calibration is underway.
