collaboration:
Following the enhanced XRT position (Beardmore et al. GCN 8872) we
re-analyzed our VLT optical and NIR images of the field of GRB 090201
(D'Avanzo et al. GCNs 8869, 8871). We find an object at the following
coordinates (J2000):
R.A. = 06:08:12.48
Dec. = -46:35:24.2
+/- 0.5"
consistent with the enhanced XRT position. Preliminary photometry of
this object gives R ~ 24.6 and J ~ 21.8. The moderate red color suggests
that this object likely is the afterglow of
GRB 090201.
Further observations are ongoing.
