V. Rumyantsev (CrAO), A. Pozanenko (IKI) report on behalf of larger GRB
follow-up collaboration:
We observed the field of the Swift GRB 101008A (Baumgartner et al., GCN
11318) with ZTE telescope of SAI MSU observatory on Oct. 12 (UT) 18:57 -
20:42. We clearly detect objects S1 and S3 (Moskvitin et al., GCN 11324) in
coordinates (J2000) RA=21 55 29.91, Dec=+37 03 56.6 and RA=21 55 29.85,
Dec=+37 04 05.0, correspondingly. We do not detect the object S2
(Moskvitin et al., GCN 11324; Nardini et al., GCN 11326). The photometry is
based on the same USNO star as Moskvitin et al.
Source, T0+, Filter, Exposure, mag., Upper Limit (3 sigma)
(mid, d) (s)
S1 4.1297 R 97x60 21.0 +/- 0.1 22.4
S2 4.1297 R 97x60 21.6 +/- 0.2 22.4
Since we do not detect the afterglow candidate S2 up to R=22.4 we can
confirm the GRB 101008A afterglow detection.
