Davis,\nof Los Alamos National Laboratory report:\n\nThe RAPTOR network of robotic optical telescopes made follow-up observations\nof Swift trigger 585128 (Melandri, et al., GCN 15760).  Our narrow-field\ninstruments in Los Alamos, NM,  began imaging at 03:25:05.19 UT, 65.7 seconds\nafter the BAT trigger time.  Our RAPTOR-T robotic telescope measured the\ncounterpart simultaneously in SDSS g', r', i', and z' bands through the first\n1000 seconds after the BAT trigger.  In r' band, the counterpart is at\nmagnitude 14.72 +- 0.04 at T+68.22 seconds.  By T+217.21, the source had\nfaded to r' magnitude 16.24 +- 0.07, consistent with the P60 observations\n(Perley, et al., GCN 15761).  The counterpart fades monotonically during the\nobservation interval.  Our images were calibrated to the SDSS DR9 catalog.",
