Swift/UVOT team
The Swift/UVOT began observing the field of GRB 060219 at 22:49:50 UT
on 19th February 2006, 105s after the BAT
trigger (A.Moretti et al. GCN 4788). No source is detected at the
refined XRT position (A. Moretti GCN 4797). Analysing all the data from
the first 7000s we obtain the following 5 sigma upper limits:
Filter T_range(s) Exp(s) 5sigUL(mag)
V 120-320 200 18.6 (the Finding Chart
exposure)
V 105-5821 584 19.2
B 327-6639 631 19.8
U 652-6434 374 19.3
UVW1 628-6230 364 19.8
UVM2 604-6025 374 20.1
UVW2 556-5617 374 20.2
White 532-6704 257 19.7
Reported times are in seconds since BAT trigger.
These magnitudes are uncorrected for Galactic extinction;
E(B-V) = 0.032.
