Pozanenko (IKI) on behalf of larger GRB follow up collaboration report:
We started observation of the Swift GRB 100901A (Immler et al., GCN 11159)
with the Z-600 telescope of Mt.Terskol observatory in R-filter on Sep.01
(UT) 17:50. In a combined image we clearly detect the afterglow (Immler et
al., GCN 11159; Guidorzi et al., GCN 11160; Ivanov et al., GCN 11161; Klunko
et al., GCN 11162).
Preliminary photometry is based on the reference star USNO-B1.0
#1127-0027231 RA(J2000) = 01 49 06.78 Dec(J2000) = +22 47 03.3 assuming
R=15.37:
