report:

Skynet observed the localization of GRB 080330 (Mao et al., GCN 7537) with 
two of the 16" PROMPT telescopes at CTIO beginning 31 seconds after the 
trigger (15 seconds after notification) in VRI.

We detect the afterglow (Klotz et al., GCN 7536) in all filters.  At 200 
seconds after the burst we measure R ~ 17.3 mag (calibrated to 11 USNO B1 
stars), at 246 seconds we measure I ~ 16.8 mag (calibrated to 11 USNO B1 
stars), and at 292 seconds we measure V ~ 16.6 mag (calibrated to 8 NOMAD 
stars).
