S. R. Oates (MSSL-UCL) reports on behalf of the Swift-UVOT team
The Swift/UVOT began settled observations of the field of GRB 110731A 75s
after the trigger (Oates et al., GCN Circ. 12215). We detect a fading
source in the white, v, b and u filters at a refined position of
RA(J2000), DEC(J2000)= 280.50413 deg, -28.537167 deg. This is equivalent to:
RA (J2000) 18:42:00.99
Dec (J2000) -28:32:13.8
with an estimated uncertainty of 0.5 arcsec (radius, 90% confidence).
This is consistent with the UVOT position reported in Oates et al.
