report on behalf of a large collaboration:
On December 15th at 15:43:50 UT we observed the field of the possible
GRB 091215 (trigger 379449, Sakamaoto et al., GCN 10280) with the the
2-m Faulkes Telescope North. Automatic observations were performed
using BVRi' filters.
We do not detect any obvious bright optical afterglow in the field of
view, that
covers almost entirely the BAT error circle reported by Sakamoto et
al. (GCN 10280).
We calibrated our images using SDSS for the i' band and USNOB-1 for the
R band and derived conservative upper limits for the OT :
