The Faulkes Telescope North observed the position of GRB080604. We confirm 
the detection of an optical transient (La Parola, GCN 7800), with a 
position of (J2000):

RA =   15 47 51.65
Dec = +20 33 28.1

In the first 10 second exposure, starting 5:42 minutes after the BAT 
trigger, we estimate a magnitude of R = 20.12 +/- 0.15 with respect to the 
USNO-B1.0 star at 15:47:52.50, +20:34:24.4.
