and M. H. Siegel (PSU) report on behalf of the Neil Gehrels Swift
Observatory Team:

Swift Triggers 1209369 and 1209370  are not astrophysical events. 
They were caused by misidentifcation of a known source (in this case, 
Sco X-1) when the star trackers had lost lock.   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. 
GCN 34709 lists sources which BAT currently sees, so notices
with coordinates near these locations should be treated as suspect.
