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."
