K. L. Page (U Leicester), D. M. Palmer (LANL) and
T. M. Parsotan (GSFC/UMBC/CRESSTII) report on behalf of the Neil
Gehrels Swift Observatory Team:

Due to a failure of the on-board star trackers to achieve lock,
a known source (Sco X-1) was misidentified as a GRB, producing
a false alert (Swift Trigger 1180055).  This is not an interesting
astrophysical event.
