Skynet observed the INTEGRAL/IBAS localization of GRB 090702 (Paizis et
al., GCN 9603) with the 14" GORT telescope at Hume Observatory in
California beginning 18.2 hours after the the trigger in I.
We do not detect the afterglow (Sbarufatti & Mangano, GCN 9607). Stacking
only images that increase the limiting magnitude yields:
