V. Rumyantsev (CrAO), A. Pozanenko (IKI) report on behalf of larger GRB
follow-up collaboration:
We observed the afterglow (Clemens et al., GCN 7948, Fynbo et al., GCN
7949) of GRB 080707 (Schady et al., GCN 7947) in R-band on July 8 between
(UT) 00:00:26 - 00:49:43 with Zeiss-1000 (Simeiz) telescope of CrAO
observatory.
Based on USNOB1.0 star with ID 1231-0038095 at RA = 02:10:27.08 , Dec.
+33:06:32.5 (R2 = 17.11) we estimated brightness of the afterglow on
0.6647 days:
T0+ Exposure R_mag
(mid)
0.6647 d 16x180 s 21.22 +/- 0.25
Taking into account early photometry (Fynbo et al., GCN 7949, Clemens et
al., GCN 7948) one may suggest a plateau or re-brightening phase of the
afterglow light curve between 0.07 and ~1 days after burst onset..
