report:


Further monitoring of the afterglow candidate (Jelinek et al.
7145) using 4.2 meter William Herschel Telescope confirms the
decay nature of the source, suggesting the source is really the
optical afterglow of GRB 051028.

Our observation 15 h after the burst show that the OT magnitude 
has decayed considerably and it is around 23 in R band.

We have posted the searchmap to the following website:
