V. Rumyantsev (CrAO), A. Pozanenko (IKI), A. Volnova (SAI MSU) report on
behalf of larger GRB follow-up collaboration:
We observed the field of the INTEGRAL GRB 100713A (Mereghetti et al. GCN
10951) with Shajn telescope of CrAO in VRI-filters starting July, 13 (UT)
21:56, i.e. 7.4 hours after burst.
We do not detect any sources in enhanced XRT error circle (D'Elia et al. GCN
10960). The photometry of stacked images based on SDSS star
J170053.83+282355.1 assuming R=16.46, I=16.24 and V=16.78 (the magnitudes
obtained from Lupton's SDSS ugriz -> VRI transformations).
T0+ Filter, Exposure, Upper Limit
(mid, d) (s)
0.3539 V 43x60 24.0
0.3546 R 43x60 24.0
0.3553 I 43x60 23.2
Since we do not detect the source observed at 3.75 hours after burst (GCN
10962) we can suggest the source reported in GCN 10962 as the afterglow
candidate.
