TITLE: GCN CIRCULAR NUMBER: 16498 SUBJECT: GRB 140629A: additional P60 observations DATE: 14/07/01 06:22:11 GMT FROM: Daniel Perley at Caltech D. A. Perley (Caltech) and S. B. Cenko (NASA/GSFC) report: We acquired additional imaging of the afterglow of GRB 140629A (Lien et al., GCN 16477; Yurkov et al. GCN 16478) with the Palomar 60-inch (P60) robotic telescope on UT 2014-07-01 between 04:23 and 04:52, acquiring 9x180s exposures in the r' filter. We measure a magnitude of: r = 22.92 +/- 0.14 (t_mid = 1.598 days) This indicates a relatively rapid decay index of alpha=1.87 since our observation the previous night (see also Garnavich and Rose, GCN 16492).
