M.C. Stroh (PSU), J. Kennea (PSU), D. Burrows (PSU), K. Page (U. Leicester) and P. A. Evans (U. Leicester) report on behalf of the Swift Team:
Swift-XRT has observed the error circle of the MAXI GRB 140221A in a
series of observations tiled on the sky. The total exposure time is 4.9
ks spread over 7 fields; the maximum exposure within the sky observed
was 1.4 ks. The observations started 10.9 ks after the MAXI trigger.
Within these data there are 2 objects detected, both of which are catalogued in
X-rays.
