Skynet observed the Swift/BAT localization of GRB 090929B (Pagani et al.,
GCN 9963) with the 14" Dark Sky Observatory telescope in North Carolina
beginning 12.0 minutes after the trigger in I.
We do not detect the afterglow (Pagani et al., GCN 9963, Wren et al., GCN
9967) within the enhanced Swift/XRT localization (Goad et al., 9964; Page,
GCN 9965). However, the nearby I = 9.07 mag (USNO B1) star complicates
photometry.
