TITLE: GCN GRB OBSERVATION REPORT NUMBER: 2983 SUBJECT: GRB 050124: NIR afterglow confirmed with Keck/NIRC DATE: 05/01/26 11:52:36 GMT FROM: Edo Berger at Carnegie Obs E. Berger (Carnegie Observatories) and S.R. Kulkarni (Caltech) report on behalf of a larger collaboration: "We re-observed the 8-arcsec XRT error circle (GCN 2975) of GRB 050124 (GCN2972) with Keck/NIRC on January 26.47 UT. A total of 18 min were obtained in the Ks band. We find that object C1 in our previous Keck/NIRC image (GCN 2978) has faded by about 0.5 mag, while object C2 remained constant in flux. We therefore conclude that C1 is the afterglow of GRB 050124." This message may be cited.
