I. Cotoros, A. Mahabal, S. Yost, and A. Diercks report on behalf of
the Caltech-NRAO-CARA GRB collaboration:
"We imaged the entire IPN error region of GRB000604 (Hurley et al, GCN #687)
with the Palomar 60" telescope from June 6.24 - 6.28 UT. The error region was
covered by two pointings with three 500s integrations in Gunn-r at each
pointing. Although the seeing was rather poor (1.5" FWHM), the combined frames
are significantly deeper than DPOSS (Djorgovski, astro-ph/9809187) images of
the field (limiting magnitude Gunn-r~20.5). Visual inspection of the IPN error
region reveals no new objects above the DPOSS limit."
