TITLE: GCN GRB OBSERVATION REPORT NUMBER: 1598 SUBJECT: GRB021004: not fading anymore? DATE: 02/10/07 19:43:01 GMT FROM: Krzysztof Z. Stanek at CfA GRB021004: not fading anymore? K. Z. Stanek, D. Bersier, J. Winn (Harvard-Smithsonian Center for Astrophysics), P. Garnavich (Notre Dame) report: R-band images of the afterglow associated with GRB 021004 (GCN 1564) were obtained with the Fred L. Whipple Observatory 1.2m telescope on Oct. 7 between 02:43 and 11:09 UT. The afterglow seems to have stopped fading. We give below our last measurement from the night of Oct. 6 and our last measurement on Oct. 7 Date Time R err_R ----------------------------- Oct 6 11:25 UT 20.08 0.05 Oct 7 11:09 UT 20.09 0.06 This could be due to the presence of a bright host galaxy, but PSF fitting shows no residual as would be expected from an extended source. Furthermore, such a bright host galaxy would be in conflict with the upper limits of Wood-Vasey et al. (GCN 1572). This message may be cited.
