E.S. Rykoff (UCSB), report on behalf of the ROTSE collaboration:
ROTSE-IIIc, located at the H.E.S.S. site at Mt. Gamsberg, Namibia,
responded to GRB 081008 (Swift trigger 331093). The first image was at
19:58:51.3 UT, 41.9 s after the burst (8.3 s after the GCN notice time).
The unfiltered images are calibrated relative to USNO A2.0. We detect a
14.5 magnitude, brightening source with coordinates:
18:39:50.0 -57:25:52.0 (J2000), with positional
uncertainty of 1" or better
start UT mag mlim(of image)

19:58:51.3 14.5 16.2
This source is not visible in DSS (second epoch), 2MASS or the MPChecker
database.
