GRB 050801
E.S. Rykoff (U Mich), S.A. Yost (U Mich), W. Rujopakarn (U Mich) report 
on GCN 3723 on behalf of the ROTSE collaboration:

ROTSE-IIIc, located at the H.E.S.S. site at Mt. Gamsberg, Namibia,
responded to GRB 050801 (Swift trigger 148522). The first image was at 
18:28:23.9UT, 21.9s after the burst (7.9s 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), with coordinates:

RA 13:36:35.4  DEC -21:55:42.0 (J2000)

The limiting magnitude was 17.0 and the object of magnitude 15.0.

Arne Henden, Director AAVSO and others suggest European observers try 
and image and measure this new object as a matter of urgency.
