report
We have observed the complete errorbox of HETE trigger 3951
(Hurley et al, GCN 4172) with the prime focus camera of
William Herschel Telescope at La Palma starting 21:42UT (ie.
~7h after the GRB).
We detect an object within the XRT errorbox (Racusin et al,
GCN 4174) at coordinates RA 01:48:15.01 Dec 47:45:09.2 (+/-
1.0", J2000), with a rough magnitude R=22, which is not
present in DSS. Further observations will be needed to confirm
whether this is indeed the optical afrterglow of GRB051028.
The image limit is ~24.2.
