Perley (Caltech) report on behalf of a\nlarger collaboration:\n\nWe have observed the location of the Swift GRB130701A (Kuin et al., GCN\n14953) with the robotic Palomar 60 inch telescope. Observations were\nobtained in non-photometric conditions in the r', i', and z' filters\nbeginning at 06:52 UT on 2013 July 1 (2.58 hr after the Swift trigger).\nUsing nearby point sources from SDSS for photometric calibration, we\nmeasure afterglow magnitudes of r' = 19.57 +/- 0.12 and i' = 19.36 +/-\n0.10 at approximately this time.  Compared with the earlier detection from\nthe NOT (Leloudas et al., GCN 14954), this implies a power-law decay index\nof alpha ~ 1.0.",
