A. Yoldas, G. Szokoly (all MPE Garching) report for the GROND team:
We started observing GRB 071031 (trigger 295670) simultaneously in grizJHK
with GROND, mounted at the 2.2m MPI/ESO telescope at La Silla (Chile),
about 60 sec after the alert. A bright object (r~15) is seen in all filters,
including the g-band, implying a redshift smaller than 3.5.
The coordinates are
RA (2000.0) = 00h 25m 37.2s
Decl (2000.0) = -58d 03' 30"
located within the XRT error circle, and consistent with the UVOT position.
