and E. Troja (U Leicester/INAF-IASFPA) report on behalf of the Swift
Team:

Shortly before 2008-03-18 01:50 UT, Swift lost star tracker lock. 
This caused the Burst Alert Telescope (BAT) to detect Sco X-1 at the
wrong location, leading to trigger 306745.  This is not a GRB. 

Star tracker recovery operations are in progress.
