Nysewander, E. Speckhard, P. Taylor \nand J. A. Crain report\n\nSkynet observed the Swift/XRT localization of GRB 130610A (Cummings et \nal., GCN 14842, Swift trigger #557845), starting at 2013-06-10, 03:14:05 \nUT (t=2.03m post-trigger), with three 16\" telescopes of the PROMPT array \nat CTIO, Chile.  We detect a fading afterglow in B, V and I bands at: RA \n= 14:57:40.9, Dec = 28:12:25.5 (J2000.0), consistent with the UVOT \nsource position reported in GCN 14842.\n\nThe afterglow rises until t~3.4m, at which time the apparent magnitudes \nare B~18.1, V~17.1, I~16.6.  A preliminary light curve is at:\nhttp://www.skynet.unc.edu/grb/grb130610a.png\n\nMagnitudes are in the Vega system and photometry is calibrated to 4 SDSS \nstars in the field.\n\nSkynet observations are ongoing.",
