A.P. Beardmore and K.L. Page (U. Leicester) report on behalf of the
Swift-XRT team :

The Swift-XRT started observing the field of GRB 090201 (Oates et al,
GCN Circ. 8865) in photon counting mode at 18:50:40.7UT, 63.6 minutes
after the trigger. In 1.4 ks of promptly downlinked data we detect
a source at a position of RA, Dec = 92.0530, -46.5888, which is

RA (J2000)  =   06h 08m 12.74s
Dec (J2000) =  -46d 35m 19.8s

with an uncertainty of 3.5 arcsec (radius, 90% containment). The source is
55.5 arcsec from the  reported BAT position and within its error circle.
We do not have sufficient data at this stage to tell if the source is
