TITLE: GCN CIRCULAR NUMBER: 15628 SUBJECT: GRB 131229A: P60 nondetection DATE: 13/12/29 07:15:30 GMT FROM: Daniel Perley at Caltech D. A. Perley (Caltech) reports on behalf of a larger collaboration: The robotic Palomar 60-inch telescope automatically responded to GRB 131229A (Page et al., GCN 15627) and began a sequence of 60-second image starting at 06:44:54 UT, 5.5 minutes after the burst. In the initial r-band image we identify no sources within the XRT error circle down to a limiting magnitude of R > 20.5. No source in the error circle is detected in the i- or z-band filters either. We do detect a source not present in USNO B1.0 well north of the XRT error circle at RA=05:40:55.702, dec=-04:23:21.11 (J2000). It does not appear to be fading in images taken so far. Further P60 observations are ongoing. NIR observations are encouraged.
