B. E. Schaefer (Louisiana State), E.S. Rykoff (UCSB), W. Rujopakarn
(Steward), S. B. Pandey (U Mich), W. Zheng (U Mich), report on behalf of
the ROTSE collaboration:
ROTSE-IIIc, located at the H.E.S.S. site at Mt. Gamsberg, Namibia,
responded to GRB 100814A (Swift trigger 431605). The first image was at
03:55:01.1 UT, 289.8 s after the burst (4.1 s after the GCN notice time).
The unfiltered images are calibrated relative to USNO A2.0. We detect a
new object, not visible in the DSS (second epoch), nor in our first set of
observations with coordinates:
01:29:53.67 -17:59:41.58 (J2000), with positional uncertainty
of 1" or better
start UT mag mlim(of image)

object marked 29 is the candidate in question.
Continuing observations are in progress.
