Skynet observed the Swift/XRT localization of GRB 130610A (Cummings et
al., GCN 14842, Swift trigger #557845), starting at 2013-06-10, 03:14:05
UT (t=2.03m post-trigger), with three 16" telescopes of the PROMPT array
at CTIO, Chile. We detect a fading afterglow in B, V and I bands at: RA
= 14:57:40.9, Dec = 28:12:25.5 (J2000.0), consistent with the UVOT
source position reported in GCN 14842.
The afterglow rises until t~3.4m, at which time the apparent magnitudes
are B~18.1, V~17.1, I~16.6. A preliminary light curve is at:
Magnitudes are in the Vega system and photometry is calibrated to 4 SDSS
stars in the field.
Skynet observations are ongoing.
