P. O'Brien, E. Rol, N. Bannister (Leicester) report:
The 2-m Faulkes Telescope South (Siding Spring) robotically followed
up GRB080229 (SWIFT trigger 304379) starting 4.6 min after the GRB
trigger time. The automatic "detection mode" procedure did not find
any afterglow. In manual inspection of later observations we do not
find any optical candidate corresponding to the XRT X-ray afterglow
(Cannizzo et al., GCN 7335) to the following limiting magnitudes.
Magnitude zero points are relative to the USNO measure of R=13.3 for
the adjacent bright star.
