(U. Leicester) report:

The 2-m Faulkes Telescope North (Hawaii) automatically reacted to the 
INTEGRAL trigger 5283 and possible GRB 080603 and started observing the 
field at 1.3 min after the trigger.

We detect an optical afterglow candidate at:
RA 18:37:38.1,
dec +62:44:39.4.

We estimate the magnitude of the source (calibrated to USNO-B1.0 
catalogue) to be I=20.3+-0.3 at t_0+5.93 min and R=19.6+-0.3 at t_0+7.37 min.
