GCN Circular 14313
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 XRT error circle (D. Malesani, GCN 14263) of GRB130305A (Fermi384176354, J. R. Cummings, GCN 14257) 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 2013-03-06 at 05:13:35 and 05:56:17 UTC, 17.6 and 18.3 hours after the trigger. We find no point source, fading or otherwise, to 5-sigma limiting magnitudes of 20.8 and 20.8.
