TITLE: GCN CIRCULAR NUMBER: 16491 SUBJECT: GRB 140629A: P60 observations DATE: 14/06/30 06:10:50 GMT FROM: Daniel Perley at Caltech D. A. Perley (Caltech) and S. B. Cenko (NASA/GSFC) report: We imaged the location of Swift GRB 140629A (Lien et al., GCN 16477) with the Palomar 60-inch (P60) robotic telescope on UT 2014-06-30 between 04:10 and 04:44 UT, in the r' filter. We acquired 10 exposures of 180 seconds each. The optical afterglow (Lien et al., GCN 16477; Yurkov et al. GCN 16478) is well-detected in the stacked image. Comparing to SDSS field stars, we measure a magnitude of: r = 20.91 +/- 0.03 (t_mid = 0.590 days) Further observations are ongoing.
