TITLE: GCN GRB OBSERVATION REPORT NUMBER: 4148 SUBJECT: GRB 051022: Magellan NIR imaging DATE: 05/10/23 08:07:53 GMT FROM: Edo Berger at Carnegie Obs E. Berger and P. Wyatt (Carnegie Observatories) report: "We observed the error circle of GRB 051022 (GCN 4131) with the PANIC near-IR camera on the Magellan/Baade telescope starting on 2005 Oct 22.105 UT (13.4 hr after the burst). We obtained a total of 18 min in the J and K bands. Within the XRT error circle (GCN 4141) we detect a single source which coincides with source B of Castro-Tirado et al. (GCN 4143). This source is clearly extended. We also detect source A of Castro-Tirado et al. but note that this source is located about 1.5" outside of the XRT error circle and it is also extended."
