J. P. Halpern (Columbia U.) and N. Mirabal (U. Michigan) report
on behalf of the MDM Observatory GRB follow-up team:
"We took a single 60 s R-band exposure of the Swift BAT location of
GRB 060507 (Barbier et al., GCN 5084) with the MDM 1.3m telescope
on May 7 02:57 UT, 64 minutes after the trigger. We see no new object
within the 3' error circle, or at the XRT candidate position of
Vetere et al. (GCN 5085), to a limit of approximately R=19.2.
Evening twilight and telescope pointing constraints prevent any
further observations.
