TITLE: GCN CIRCULAR NUMBER: 1225 SUBJECT: GRB 020124: Optical observations DATE: 02/01/26 15:53:30 GMT FROM: Dale A. Frail at NRAO J. S. Bloom, on behalf of the larger Caltech-NRAO-GRB collaboration, reports: "Using the JCAM optical imaging instrument mounted at the Palomar 200" telescope, we observed the field of GRB 020124 (Ricker et al., GCN #1220; Hurley et al., GCN #1223) on Jan 26.33 UT centered on the position of the optical transient (Price et al., GCN #1221). In non-photometric conditions (moderate to thick cirrus) we detect a faint source in the Sloan r' filter (24 x 200 sec total exposure) which is coincident with the transient position. This is in agreement with the imaging results reported earlier from Gorosabel et al. (GCN #1224). The coincident source is not detected in Bessel I-band (8 x 140 sec total exposure). An image of the field is posted at: http://www.astro.caltech.edu/~jsb/grb020124-jcam.gif We wish to thank A. Barth, W. W. Sargent, R. Burruss, and J. Mueller for assistance with these (remote) observations." This message may be cited.
