and P. Hewett (IoA, Cambridge) report:
We imaged the Swift detected burst GRB 060604 (Page et al. GCN 5212)
with the AUX-port camera on the WHT at June 5.169 UT. A 300s R-band exposure
shows a source at the position of the UVOT counterpart which has apparently
faded, thus confirming the afterglow ID.
By comparison with the two nearby USNO stars, we estimate a magnitude
of R=21.4 with an uncertainty (given the rough calibration) of 0.3 mag.
