TITLE: GCN CIRCULAR
NUMBER: 11680
SUBJECT: GRB 110207A: Swift-XRT observations
DATE: 11/02/09 14:44:37 GMT
FROM: Phil Evans at U of Leicester <pae9 at star.le.ac.uk>
P.A. Evans and O.M. Littlejohns (U. Leicester) report on behalf of the
Swift team:
Swift observed the field of GRB 110207A (Littlejohns et al., GCN Circ.
11658) for 5 ks from T0+99 ks to T0+112 ks; earlier observations were
impossible due to the proximity of the GRB to the Moon. We find no X-ray
sources in the BAT field of view, placing a 3-sigma upper limit on the
afterglow brightness of 7.6e-14 erg/cm^2/sec during this interval
(0.3-10 keV; assuming a typical GRB spectrum). Due to the proximity of
the GRB to the Sun, no further observations are planned.
This circular is an official product of the Swift-XRT team.
