M. Andreev, A. Sergeev (Terskol Branch of Institute of Astronomy), Ju. Babina (CrAO), A. Pozanenko (IKI) on behalf of larger GRB follow up collaboration report: We observed the field of GRB 081203 (Parsons et al, GCN 8595) with the Z-600 telescope of Mt. Terskol observatory between (UT) Dec.03 14:29-14:38 (unfiltered exposures of 15 s), Dec.03 14:50 - Dec.04 01:45 (R-band exposures of 60 s), and starting (UT) Dec.04 15:27. In mid time Dec.04 (UT) 00:50 the afterglow is detected on combined images and R=19.5 +/-0.2. In mid time Dec. 04 (UT) 15:32 we do not detect the afterglow up to R=20.6 (3 sigma). The photometry is still preliminary and basen on star of SDSS J153155.64+632959.4 (=USNO-B1.0 1534-0214259), assuming R=14.69.
