Crain, A. Foster, T. Brennan, J. Haislip, J. Styblova, and A. Trotter report:
Skynet observed the localization of GRB 080319B (Racusin et al., GCN 7427)
with three of the 16" PROMPT telescopes at CTIO beginning 32 seconds after
the trigger (15 seconds after notification) in UVRI.
We detect the afterglow (Racusin et al., GCN 7428) in all filters. At 92
seconds after the burst we measure V ~ 8.6 mag (calibrated to 3 NOMAD
stars), and at 147 seconds we measure I ~ 8.9 mag (calibrated to 6 USNO B1
stars).
