E.S. Rykoff (U Mich), B. E. Schaefer (Louisiana State), report on behalf
of the ROTSE collaboration:
ROTSE-IIIa, located at Siding Spring Observatory, Australia, responded
to GRB 060605 (Swift trigger 213630). The first image was at 18:16:33.3
UT, 48.7 s after the burst (5.4 s after the GCN notice time). The
unfiltered images are calibrated relative to USNO A2.0. We detect a 16.3
magnitude, steady source with coordinates:
21:28:37.3 -06:03:30.6 (J2000)
