V. Rumyantsev (CrAO), D. Shakhovkoy, A. Pozanenko (IKI) report on behalf of
larger GRB follow-up collaboration:
We observed the afterglow (Immler et al., GCN 11159) of the Swift GRB
100901A (Immler et al., GCN 11159) with AZT-11 telescope of CrAO
observatory on September 3 (UT) 20:24 - 21:18 and 5 (UT) 22:39 - 23:51. The
afterglow photometry is based on the same reference stars of SDSS DR7 used
in our previous reports (GCNs 11191, 11200):
T0+ Filter, Exposure, mag.
(mid, d) (s)
2.3045 R 19x180 20.07 +/- 0.08
4.4045 R 18x180 21.10 +/- 0.20
The photometry is compatible with photometry at the same period (4.39 -
4.55 days) reported by Kann et al (GCN 11236).
