The 2m Faulkes North Telescope (Hawaii) automatically reacted to 
the Swift burst GRB060923C (trigger 230711, Stamatikos et al. GCN 5591). 

Observations started about 4.2 min after the trigger time and were
performed in R and i' bands. From the stacked images we do not detect 
any new source down to:
