TITLE: GCN CIRCULAR NUMBER: 15719 SUBJECT: GRB 140110A: OT detection in Swift/UVOT imaging DATE: 14/01/10 21:31:17 GMT FROM: Dong Xu at DARK/NBI D. Xu (DARK/NBI) reports Inspection of the UVOT u-band image of the field1 of the tiled Swift observations (Evans, GCN 15715) reveals a very bright optical source, no present at DSS, at coordinates R.A. = 01:54:57.50 Dec. = -36:16:38.71 Error Circ. ~ 1.5 arcsec No known minor planet, near-Earth object, and comet would appear at this position at the UVOT observational time. Thus this object could be the optical afterglow of GRB 140110A, and may worth some photometric follow-ups to check its variation.
