S. Johnson, J. Haislip, D. Reichart, M. Nysewander, A. LaCluyze, K.
Ivarsen, J. A. Crain, A. Foster, and A. Trotter report:

Skynet observed the localization of z = 5.6 (Fynbo et al., GCN 5651) GRB
060927 (Barbier et al., GCN 5627) with four of the 16" PROMPT telescopes at
CTIO beginning 9.8 hours after the burst in Ugriz.

We do not detect the afterglow (Schaefer et al., GCN 5629) to 3-sigma
limiting magnitudes of z = 20.4 mag at a mean time of 12.1 hours after the
burst, i = 21.2 mag at 15.1 hours, and r = 21.7 mag at 14.7 hours.
