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.
