GRB 110801A: ROTSE-III Detection of re-brightening from OT

W. Zheng (U Mich), T. Guver (U Arizona), report on behalf of the ROTSE
collaboration: 


ROTSE-IIId, located at the Turkish National Observatory at Bakirlitepe,
Turkey, responded to GRB 110801A (Swift trigger 458521; Pasquale et al.
GCN 12228). The first image was at 19:52:57.7 UT, 194.7 s after the
burst (8.7 s after the GCN notice time). The unfiltered images are
calibrated relative to USNO A2.0. We detect the OT at UVOT location (GCN
12228), the OT appeared to be re-brightening to ~15.0 mag at ~1400s
after the burst. Continuing observations are in progress.
