report:

Skynet observed the localization of GRB 080916A (Ziaeepour et al., GCN 
8237) with four of the 16" PROMPT telescopes at CTIO beginning 56 
seconds after the trigger in UBVRI.

We detect the afterglow (Fugazza et al., GCN 8238) in I.  At 56 seconds 
after the burst we measure I ~ 17.7 mag (calibrated to 5 USNO B1 stars).
