GCN Circular 10767
V. Rumyantsev (CrAO), A. Pozanenko (IKI) report on behalf of larger GRB follow-up collaboration: We observed the field of the Swift GRB 100514A (Markwardt et al. GCN 10759) with Shajn telescope of CrAO between (UT) May 15 00:04:38 and 15T01:10:33 under good weather conditions and mean seeing of 2 arcsec. Inside the enhanced XRT error circle (Goad et al. GCN 10762) we detect the object with coordinates RA(J2000): 21 55 17.46 Dec(J2000): +29 09 36.13 with uncertainties of 0.3" in each coordinates. The photometry of the object based on USNO-B1.0 star 1191-0563318 (J2000) RA= 21:55:19.80 Dec= +29:10:10.0 (assuming R2=19.25) is following: T0+ Filter, Exposure, mag. (mid, d) (s) 0.2390 R 57x60 23.2 +/- 0.2 The afterglow candidate reported by Marshall and Markwardt (GCN 10766) is fading by ~2 mag. within 5.7 hours, and hence we confirm the afterglow.
