D. Perley, N. Butler, and Y. Kemper (UCB) report:

Starting at 2006-06-07 10:34 UT (5.37 hours after the trigger) we imaged 
the field of GRB060607 (GCN 5233) using the Lick 3m telescope equipped 
with the Gemini IR camera under high airmass conditions and intermittent 
clouds.  We do not detect the afterglow (GCN 5233, GCN 5234) down to a 
preliminary limiting magnitude of J=17.2 (3 sigma) in a series of 
dithered exposures lasting 60 minutes.
