GCN Circular 2150
P.A. Price, R. McNaught, G.J. Garradd, M.A. Verrender and T.M. Smith (RSAA, ANU) report: We have re-observed the GRB 030418 optical afterglow candidate (GCN #2148) with the Siding Spring Observatory 40-inch telescope + Direct Imager. Our observations consisted of another 5x300 sec exposures in R-band, commencing at April 18.61 UT. Comparison of our two epochs reveals that the source faded by about 1 magnitude between the two observations, being R ~ 19.8 mag in the second epoch. We therefore believe this source is the optical afterglow of GRB 030418. This message may be cited.
