Skynet observed the Swift/BAT localization of GRB 090530A (Cannizzo et al., GCN
9438) with the 14" Dark Sky Observatory telescope in North Carolina beginning
61.8 minutes after the trigger in RI.
We detect the afterglow (Cannizzo et al., GCN 9438). Stacking only images that
increase the limiting magnitude yields:
