Styblova, A. Trotter, and E. Weaver report:

Skynet observed the localization of GRB 081007 (Baumgartner et al., GCN
8330) with four of the 16" PROMPT telescopes at CTIO beginning 41 seconds
after the trigger (24 seconds after notification) in UBVRI.

We detect the afterglow (Baumgartner et al., GCN 8330) in BVRI.  At 121
seconds after the burst, we measure I ~ 14.8 mag (calibrated to 6 USNO B1
stars).
