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.
