V. Rumyantsev, Yu. Efimov (CrAO), A. Pozanenko (IKI) report on behalf of
larger GRB follow-up collaboration:
We observed the optical afterglow of GRB080810 (Page et al., GCN 8080)
in R-band on Aug.10 between (UT) 23:17:05 - 23:48:32 with AZT-8 telescope of
CrAO. The afterglow is detect in a separate images in coordinates RA(J2000)
= 23 47 10.4, Dec(J2000) = +00 19 11.0 with uncertainty 0.5". The
coordinates are consistent with reported early (Page et al. GCN 8080,
Rykoff GCN 8084, A. de Ugarte Postigo et al. GCN 8090).
Based on USNO-B1.0 star RA (J2000) = 23 47 11.12, Dec. (J2000) = +00 16
38.30, R=16.30 we estimated brightness of the optical afterglow:
T0+, Exposure, R_mag, err
