collaboration:
"We carried out I-band observations of the GRB 091117 error box
(Cummings et al., GCNC 10171) with the 1.5m OSN telescope. The
observations were performed on Nov 18.895-18.958 UT (27.7-29.3 hours
post GRB). Visual comparison with the DSS does not reveal any new
source in the error box brighter than I~20.5."
