report:
SkyNet observed the localization of GRB 060605 (Page et al., GCN 5221)
beginning at 06:55:02 UT on 06/06/2006, 12.7 hours after the initial
trigger with the 14.5" TTT Telescope and the 14" GORT (GLAST Optical
Robotic) Telescope, located at Hume Observatory, California:
Filter Start (UT) Stop (UT) Exposure Total (hr) Telescope
V 08:20:36 09:43:56 160s x 26 1.2 TTT
Red* 06:55:02 10:10:50 160s x 32 1.4 TTT
V 09:47:32 11:32:12 160s x 38 1.7 GORT
B 08:47:59 09:44:22 160s x 21 0.9 GORT
Observations were taken under poor conditions. We do not detect the
afterglow (Rykoff et al., GCN 5220) down to 3-sigma limiting magnitudes of
V > 20.0 at a mean time of 14.8 hours, Red > 18.5 at 13.4 hours with TTT,
and V > 19.1, B > 16.7 at 16.4 and 15.0 hours respectively with GORT.
*Red well approximates the R-band.
