collaboration report:
We are continuing observation (Andreev et al, GCN 8608) of the GRB081203B
(Copeteet et al, GCN 8600) with the Z-600 telescope of Mt. Terskol
observatory. A set of R-band exposures was taken between Dec.05 (UT)
02:33-03:19. In a combined image of 30x90 s at mid time Dec. 05 (UT) 02:56
we still detect afterglow of the GRB081203B (Schady et al, GCN 8606). A
photometry of the afterglow is 20.9 +/- 0.3. The photometry is based on
USNO-A2.0 star 1275_08617401 (RA 15 15 10.21 Dec: +44 26 01.4) assuming
R=17.1.
