Styblova, A. Trotter, and E. Weaver report:
Skynet observed the localization of GRB 081029 (Sakamoto et al., GCN 8435)
with three of the 16" PROMPT telescopes at CTIO beginning 92 seconds after
the trigger (64 seconds after notification) in BVRI.
We detect the afterglow (Rykoff et al., GCN 8436) in individual exposures in
VRI. At 147 seconds after the burst we measure V ~ 16.8 mag (calibrated to
9 NOMAD stars), at 174 seconds we measure R ~ 15.7 mag (calibrated to 10
USNO stars), and at 296 seconds we measure I ~ 15.8 mag (calibrated to 10
USNO stars).
