W. Rujopakarn (Steward), E.S. Rykoff (UCSB), report on behalf of the ROTSE
collaboration:
ROTSE-IIIb, located at McDonald Observatory, Texas, responded to GRB
080607 (Swift trigger 313417). The first image was at 06:07:49.0 UT, 22.0
s after the burst (6.0 s after the GCN notice time). The unfiltered images
are calibrated relative to USNO A2.0. We detect a 14.8 magnitude, fading
source with coordinates:
12:59:47.3 +15:55:10.8 (J2000), with positional uncertainty
of 1" or better
