Nysewander report:
Skynet observed the Swift/BAT localization of short-duration GRB 090621
(Curran et al., GCN 9545) with the 16" telescope at the Dolomiti
Astronomical Observatory in Italy beginning 26.2 minutes after the trigger
in Red, which we have calibrated to R.
We do not detect the afterglow (Curran et al., GCN 9545). Stacking only
images that increase the limiting magnitude yields:
