GCN Circular 4843
M. Andreev (Institute of Astronomy), E. Pavlenko (CrAO), A. Pozanenko (IKI) on behalf of larger GRB follow up collaboration report: We observed GRB 060218/SN 2006aj (Cusumano et al. GCN 4775) in V-band with the 60 cm telescope of peak Terskol observatory on Feb. 22 and Feb. 23. A series of 60 s exposures were taken in both epochs. Using SDSS pre-burst observations (Cool et al. GCN 4777) we estimate brightness of the optical afterglow + SN: Mid time, exp., V mag (UT) (s) Feb.22 17:08 147x60 s 18.00 +/- 0.01 Feb.23 18:20 12x60 s 17.82 +/- 0.03 The brightening rate in V between Feb. 22 and Feb. 23 is 0.16m per day.
