TITLE: GCN CIRCULAR NUMBER: 14451 SUBJECT: GRB 130427A: P60 early detection DATE: 13/04/27 08:56:29 GMT FROM: Daniel Perley at Caltech D. A. Perley (Caltech) reports on behalf of a larger collaboration: Upon further inspection of the P60 images, we identify a very bright optical source separated by about 51 arcseconds from the XRT afterglow location but consistent with the optical afterglow location reported by Elenin et al. (GCN 14450) The source is saturated in the early images. Further observations are ongoing. We also note that there is an SDSS galaxy at this position, suggesting a low-redshift event.
