V. Rumyantsev (CrAO) and A. Pozanenko (IKI) report on behalf of larger GRB
follow-up collaboration:
We observed the field of GRB 090814A (Ukwatta et al. GCN 9793; Updike et
al., GCN 9794) with Shajn telescope of CrAO on Aug. 14 between (UT)
19:02:44 - 19:56:58 under modarate seeing of about 1.9 arcsec. We detect
afterglow in a stacked image. The coordinates of the afterglow are (J2000)
15 58 26.36 +25 37 52.32 in a full agreement with reported earlier (A.
Updike et al., GCN 9794). The photometry against nearby USNO-B1.0 star 15
58 23.11 +25 39 07.2 16.64 R is following:
T0+ Filter, Exposure, mag., err.
(d) (s)
R 51x60 22.10 +/- 0.08
We confirm the shallow decay of the afterglow (D. Xu et al., GCN 9809) with
power law index ~0.3.
