report on behalf of larger GRB follow-up collaboration:
We observed the field of INTEGRAL GRB 080603A (Paizis et al., GCN 7790) in
R-band on June 03 between (UT) 19:16:25 - 19:43:54 with AZT-11(Nauchny)
telescope of CrAO observatory. We detect optical afterglow (Gomboc et al.,
GCN 7788; Chornock et al., GCN 7789) in coordinates
RA(J2000): 18 37 37.97
Dec(J2000): +62 44 38.9
with uncertanitie is 0.5".
Based on USNOB1.0 star with ID 1527-0313986 at RA = 18:37:55.186, Dec.
+62:45:32.28 (R1 = 16.74) we estimated brightness of the afterglow in a
combined image at 0.3424 days:
T0+, Exposure, R_mag, UL
(mid time)
0.3424 d 10x180 s 20.62 +/- 0.13 21.8
