A. Volnova (SAI MSU), E. Klunko (ISTP), and 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-33IK telescope of Sayan observatory (Mondy) starting on Feb.19 (UT)
16:16:18, i.e. 1.0 hours after the burst. Observations were carried out up
to (UT) 16:59:26. We do not detect any objects in enhanced XRT error circle
(Evans et al. GCN 10437). The upper limit (3 sigma) of stacked image of the
first series is based on several USNO-B1.0 nearby stars:
T0+ Filter Exposure mag.
