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.
