TITLE: GCN CIRCULAR NUMBER: 14192 SUBJECT: GRB 130122A: PTF P48 optical upper limits DATE: 13/02/09 15:33:37 GMT FROM: Leo Singer at CIT/PTF L. P. Singer (Caltech), S. B. Cenko (UC Berkeley), and D. A. Brown (Syracuse) report on behalf of a larger collaboration: We have imaged the 3-sigma Swift UVOT error circle (P. Evans, GCN 14143) of GRB130122A (Swift546731, S. Barthelmy, GCN 14140) with the Palomar 48 inch Oschin telescope (P48) as part of the Palomar Transient Factory (PTF). Images were obtained in the Mould R filter at 2013-01-23 at 06:27:39 and 07:11:25 UTC, 6.7 and 7.5 hours after the trigger. With sporadic cloud cover and a bright moon, we find no point source, fading or otherwise, to 5-sigma limiting magnitudes of 19.1 and 18.4.
