Rol (University of Leicester) report:\n\nWe observed the position of GRB 060908 using the Danish 1.5m telescope\nequipped with DFOSC, in R band. The optical transient (Evans et al,\nGCN 5544) is detected in all our exposures.\n\nWe performed photometry with respect to a nearby USNO-B1.0 star\n0903-0022606, for which we assume R = 18.29.  The reported error in\nour magnitude is therefore only the error in the photometry of the\ntransient. We find R = 21.57 +/- 0.04, 46 minutes after the trigger.\n\nDuring our observations between 36 and 70 minutes after the trigger,\nthe optical transient is clearly decaying: a power law fit to our data\nresults in a decay index of 1.07 +/- 0.11. The magnitude and decay\nrate suggest that the decay slowed down somewhat, after an initial\nsteep decline.",
