V. Rumyantsev, K. Antonyuk (CrAO), A. Pozanenko (IKI) report on behalf of
larger GRB follow-up collaboration:
We observed the field of Swift trigger 524642 with AZT-11 telescope of CrAO
observatory starting on June 18 (UT) 20:23:03 under favorable weather
conditions and seeing of about 2.4 arsces. At the edge of the Swift-XRT
localization (+19h 10m 22.39s -05d 47' 55.3" GRB_ERROR=5.2") we found bright
optical source which is absent on any DSS2 plates. The coordinates of the
source (J2000) 19 10 22.78 -05 47 56.4 is 5.9" away from the center of the
XRT localization and coincide with UVOT position reported in GCN/SWIFT
NOTICE.
Photometry of the source is based on the USNO-B1.0 star 0842-0520198 (19
10 23.32 -05 46 52.8) assuming R=14.70:
T0+ Filter, Exposure, OT, uplim (3 sigma)
(mid, d) (s)
0.0666 R 13x180 16.033 +/- 0.005 21.7
