Nysewander report:

Skynet observed the Swift/BAT localization of GRB 100302A (Cummings et al., 
GCN 10458) with the 16" telescope at the Dolomiti Astronomical Observatory 
in Italy beginning 2.7 minutes after the trigger (1.3 minutes after 
notification) in Red, which we have calibrated to R.

We do not detect the afterglow (Cummings et al., GCN 10458).  Stacking only 
images that increase the limiting magnitude yields:
