G. Chincarini (Un. Bicocca) report on behalf of the MISTICI collaboration:

We observed the field of GRB 081118 (Hoversten et al. GCN 8524) with the 
ESO-VLT equipped with the FORS2 camera on Nov 19.0431 UT (about 10 hours 
after the burst). We detect an object in our R-band images at the edge 
of the refined XRT error box (Evans et al. GCN 8525). The object is 
around R ~ 22.5. At present it is not possible to say if it is variable 
or not. Object coordinates are (J2000):

R.A. = 05:30:22.18
Dec = -43:18:05.3

+/- 0.5". Further analysis is ongoing.

We acknowledge support from the ESO staff, in particular Antonio de 
Ugarte Postigo.
