and J. A. Crain report

Skynet observed the Swift/BAT localization of GRB 130605A (Holland et 
al., GCN 14773, Swift trigger #557508) with three 16" telescopes of the 
PROMPT array at CTIO, Chile.  Starting at 2013-06-05, 23:43:23 UT 
(t=101s post-trigger)

We detect a fading afterglow in B, V and I bands at the position 
reported by Guelbenzu et al. (GCN 14774).  Preliminary magnitudes at 
t=10.4m are
B = 17.9
V = 17.1
I = 15.7
Magnitudes are in the Vega system, calibrated to 3 APASS stars in the 
field, and are not corrected for Milky Way extinction.

Skynet observations are ongoing.
