Further analysis of the initial UVOT data for GRB 060111 (Zane et al.,
GCN 4479) reveals a potential afterglow candidate at

RA,Dec (J2000) = 18:24:49.132  +37:36:14.47

within the refined XRT error circle (Goad et al., GCN 4481). The
source, significant at 8 sigma in an 3 arcsec radius aperture, has a
V band magnitude of 18.9 +/- 0.4 in a 200 s exposure starting at 72 s
after the BAT trigger. This magnitude is uncorrected for Galactic
extinction (E(B-V) ~0.1).
