E. Klunko (ISTP), A. Pozanenko (IKI) on behalf of larger GRB follow up
collaboration report:
We started observation of the field of GRB 110422A (Mangano et al. GCN
11957) with AZT-33IK on Apr. 22 (UT) 15:58. We detected new object, not
presented in DSS2 in coordinates (J2000) 07 28 10.972 +75 06 24.87 with
statistical uncertainty of 1" in booth coordinates. The object is close to
the current XRT position. The first image was unfiltered, while after
detection we started several series in R-filter. The brightness of the
object in the first image taken 16 min after burst onset is R=18.3 in
comparison with nearby USNOB-1.0 field stars. We suggest that the object is
the afterglow of GRB 110422A.
