Unfiltered CCD images were obtained\nunder hazy conditions beginning 1.5 hours after the\nburst. We calibrated the afterglow in SDSS-r using a\nnearby star in the Pan-STARRS catalog and constructed\nthe following light curve:\n\nDateAge     SDSS-r err\n(UT)          (hours)\nMarch 25.1403  1.483    19.29  0.14\nMarch 25.1626  2.018    19.52  0.18\nMarch 25.227    3.564    20.1   0.3\n\nBased on SDSS-r magnitudes reported by Heintz et al.\n(GCN 22535) and Guidorzi et al. (GCN 22534), we obtain\na rather shallow power-law decay index of 0.31+/-0.05\nbetween 0.5 hours and 2 hours after the burst.",
