TITLE: GCN GRB OBSERVATION REPORT NUMBER: 1670 SUBJECT: GRB021104: optical observations DATE: 02/11/04 11:53:14 GMT FROM: Weidong Li at UC Berkeley KAIT/LOSS Weidong Li, R. Chornock, S. Jha, and A. V. Filippenko (UCB) report: "Analyses of the images of the GRB021104 field taken by KAIT from 4 Nov 2002 09:47 UT to 11:18 UT showed that the possible afterglow reported in GCN #1668 did not vary in brightness, thus confirmed the finding by Fox and Price in GCN #1669. Corrigendum: in GCN #1668, the observation time should be "4 Nov 2002", also, the last sentence 'GRB020813' should be 'GRB021104'. Thanks to Jean-Luc Atteia of LAOMP, Observatoire Midi-Pyrenees (France) for the quick alert to these mistakes."
