E. Berger (Carnegie Observatories) and D.L. Kaplan (MIT) report:
"Starting on July 29.315 UT we observed the XRT position of the short
burst GRB 070729 (GCN #6678) with Persson's Auxiliary Nasmyth Infrared
Camera (PANIC) on the Magellan/Baade 6.5-m telescope. A total of 6 min
were obtained in the Ks band in 0.55" seeing. We find a single, extended
object within the XRT error circle with Ks ~ 18.2 mag, located at:
RA = 03:45:15.52
DEC = -39:19:28.7
No point sources are visible within the XRT error circle to a 3-sigma
depth of about 21.3 mag. Further observations are in progress."
