The UVOT data for GRB 060111B (Perri, et al. 2006, GCN
Circ. 4487) on January 11, 2006 has been reanalysed. We find the
following magnitudes and 3-sigma upper limits in the early UVOT
exposures. The start and stop times are relative to the BAT trigger
time, 20:15:43 UT.

The values quoted above are not corrected for the expected Galactic
extinction of E_{B-V} = 0.11 mag (Schlegel et al. 1998).
These data supercede those reported in GCN Circ. 4487. We note
that the B-band detection reported in GCN Circ. 4487 is not real, and
the initial finding chart was taken with the V filter, not the B
filter as previously reported. The UVOT team apologizes for these
errors.
