GCN Circular 15844
D. A. Perley (Caltech) and S. B. Cenko (NASA-GSFC) report: The Swift-BAT alert for GRB 140215A (Markwardt et al., GCN 15837) automatically triggered the Palomar 60-inch telescope, which slewed to the position and began started a sequence of r, i, and z images beginning at 04:09:54 UT, 2.74 minutes after the initial trigger. The optical afterglow is well-detected in all images and filters, and follow-up has continued through to the present time. The afterglow light curve fades as a simple unbroken power-law with a decay index of alpha=1.19 throughout this period. Calibrating relative to USNO-B1.0, we estimate a magnitude (in the most recent imaging, at 387 minutes post-trigger) of R = 19.93 +/- 0.13 mag. Spectroscopic follow-up is encouraged.
