GCN Circular 1099
D. W. Fox, R. Burruss, E. Berger, J. S. Bloom, S. G. Djorgovski, and S. R. Kulkarni (Caltech), with M. Haynes (Cornell), report on behalf of the larger Caltech-NRAO-CARA GRB collaboration: "R. Burrus obtained Sloan r' images of the joint HETE/IPN localization for GRB010921 (HETE trigger #1761; GCNs #1096 and #1097) with the Hale 200-inch telescope at Palomar Observatory beginning 22 hours after the trigger (22 September 03:18 UT). The instrument used was the Large Format Camera (LFC) and the observations were 4 min in duration (3 pointings). Visual comparison with the Digital Palomar Observatory Sky Survey F plate reveals no obvious new source to the depth of the DPOSS image (R ~ 20.5 mag)." This message may be cited.
