A. J. Blustin (UCL-MSSL), P. Boyd (GSFC), S. Oates (UCL-MSSL),
R. Fink (GSFC), M. Ajello (MPE), N. Gehrels (GSFC) on behalf of
the Swift/UVOT team report:
The Swift-UVOT began taking settled exposures of the field of
GRB 051016A 116 s after the BAT trigger (Boyd et al. GCN 4096).
No new source with respect to the DSS is detected within the
refined XRT error circle (Beardmore et al. GCN 4100) in summed
images down to the following 3-sigma magnitude upper limits:
Filter T_range(sec) Exp(sec) 3sigUL
V 116-41900 3345 20.3
B 483-40330 3693 21.7
U 428-47088 2542 20.7
W1 374-47026 3798 20.7
M2 320-46119 3798 21.0
W2 591-41238 3699 21.1
Where T_range is time post-trigger.
