V. Rumyantsev, D. Shakhovskoy (CrAO), A. Pozanenko (IKI) report on behalf
of larger GRB follow-up collaboration:
We observed the field of the Swift GRB 100219A (Rowlinson et al. GCN 10438)
with AZT-11 telescope of CrAO starting (UT) Feb. 19 22:54 (7.6 hours after
burst onset). We detect the galaxy (previously reported by Holland &
Rowlinson (GCN 10436), Bloom & Nugent (GCN 10437)). The coordinates of the
galaxy are (J2000) RA= 10 16 48.61, Dec= -12 33 57.15 (with uncertainties
0.5 arcsec in both coordinates). We do not detect optical afterglow
(Jakobsson et al. GCN 10430, Kruehler et al. GCN 10439). The photometry is
based on USNO-B1.0 star 0774-0276292 (assuming R=16.90):
