of the Swift/UVOT team
Further analysis of the Swift/UVOT data for GRB 060111A (Zane et al.,
GCN 4479) reveals that the afterglow candidate reported by Blustin et
al. (GCN 4482) in the initial UVOT V-band exposure has faded from view
in subsequent data. The 3 sigma magnitude upper limits from later summed
images in the different filters are as follows:
Filter T_range(s) Exp(s) 3sigUL(mag)
V 3750-4105 59 18.5
V 4757-10346 472 19.6
B 280-17141 1746 21.2
U 6042-16227 1476 20.8
W1 5838-21553 1033 20.3
M2 5633-10550 572 20.1
W2 9942-12104 435 20.1
These magnitudes are uncorrected for Galactic extinction.
