P. A. Evans (U Leicester), K. L. Page (U Leicester) and
D. M. Palmer (LANL) report on behalf of the Swift Team:
At 10:37:38 UT, the Swift Burst Alert Telescope (BAT) had lost
star-tracker lock.
As a result trigger 642296 and subsequent triggers are due to
misidentifying known sources as new GRBs.
The Flight Operations Team has been called in.
