on behalf of the MISTICI collaboration:
We observed the field of GRB 090201 (Oates et a., GCN 8865) with the
ESO-VLT in imaging mode starting about 7.5 hours after the burst.
Observations were carried out in R and I-band with the FORS2 camera.
At the edge of the XRT error circle (Beardmore et al. GCN 8868) we find
a very faint source at the following coordinates (J2000):
R.A. = 06:08:12.92
Dec. = -46:35:17.3
+/- 0.3"
Preliminary photometry of this candidate afterglow gives R ~ 25.2 and I
~ 24.1. Further observations are ongoing.
We acknowledge the VLT staff for their support, in particular E. Valenti
and J. Smoker.
