Skynet observed the Swift/BAT localization of GRB 130722A (Troja et al.,
GCN 15013, Swift trigger 563213) in the Rc and Ic bands with the 14"
GLAST Optical Robotic Telescope (GORT) at the Hume observatory in
California, beginning at t=100s post trigger and continuing until t~1hr.
In stacked exposures, we marginally detect a source in both bands at the
afterglow position reported by Melandri et al. (GCN 15015). Photometry
is calibrated to 3 USNO-B1 stars in the field:
band t[min] exp[min] mag
Rc 38 31 18.6 (+0.4, -0.3)
Ic 41 35 17.6 (+0.3, -0.2)
No further Skynet observations are scheduled.
