K. L. Page (U Leicester) and D. M. Palmer (LANL) report on behalf of
the Neil Gehrels Swift Observatory Team:
Swift continues to have star tracker loss-of-lock problems, possibly
due to current solar activity. For the near future, please verify
that the Swift GCN notices do not have the comment
COMMENTS: This trigger occured while the StarTracker had lost lock, so it is possibly bogus.
Also, the loss-of-lock triggers will tend to be reported as having
positions within a few degrees of the actual sources. BAT currently
sees the following sources, so notices near these locations
should be treated as suspect

Further retraction notices will not be published until
the Loss-of-Lock problem is cleared.
