GCN Circular 4746

Subject
GRB060210: Swift/UVOT Upper Limits
Date
2006-02-11T23:29:28Z (18 years ago)
From
Peter Brown at PSU <pbrown@astro.psu.edu>
P. J. Brown (PSU), A. Beardmore (U Leicester),
P. Schady (PSU/UCL-MSSL), N. Gehrels (GSFC)
on behalf of the Swift/UVOT team report:

The Swift/UVOT began taking data on the field
of GRB 060210 at 05:00:28 UT on 2006-02-10,
approximately 98 s after the BAT trigger
(Beardmore et al., GCN 4724). No source is
detected in the refined XRT error circle
(Beardmore et al., GCN 4733) or at the position
of the afterglow identified by Fox & Cenko (GCN 4723)
in either the 200s finding chart images or summed
images down to the following 3-sigma magnitude
upper limits:

Filter  T_range(s)  Exp(s)  3sigUL(mag)
V       98-297        200      18.9
V       98-17151      1574     20.1
B       305-504       200      19.9
B       305-28728     2557     21.3
U       3750-27815    1594     20.6
UVW1    606-12060     1289     20.8
UVM2    582-17970     1402     21.1
UVW2    535-23754     2231     21.5
White	510-29539     2170     21.4

These magnitudes are uncorrected for
Galactic extinction; E(B-V) = 0.09.

These non-detections are consistent
with the spectrum described by
Cucchiara, Fox & Berger (GCN 4729)
