(MIT) report:

We have continued to observe GRB 050509b (GCN #3383) with the imager
on the 3.5m WIYN telescope. Under improving conditions, a 600s observation
in the sloan r band beggining at 06:05 UT revealed a apparent point source
within the XRT error circle (GCN #3383) and within the detectable light of
the nearby galaxy (GCN #3386).
