GCN Circular 14231
D. A. Perley (Caltech) and S. B. Cenko (UC Berkeley) report: We imaged the BAT position of GRB 130216B (Cummings et al., GCN 14226) on 2013-02-17 (UT) in Ks-band at two different epochs: 10 one-minute exposures between 04:11 and 04:26 followed by 11 one-minute exposures between 05:27 and 05:45. The FOV covers the entire BAT error circle. No new sources are seen in the field relative to the 2MASS catalog. Digital image subtraction of the two epochs gives a limit on variability of Ks >~ 18.6 mag (5 sigma) between 9.33 and 10.63 hours after the BAT trigger. In particular, we do not identify any variable sources or pointlike objects at the location of the 2MASS galaxy mentioned by Cummings et al, which our observations resolve into a highly-inclined spiral galaxy (major axis diameter ~40 arcsec).
