Swift/BAT did not localize GRB 251106A onboard (T0: 2025-11-06T19:56:37 UTC, SVOM/ECLAIRS GCN 42605Loading...
 
 ).

In a ground search of a 10 s event file, available due to a subthreshold trigger onboard. The GRB was detected at a S/N of 7.0 in a single 10 s, 15-150 keV image starting at ~T0 + 129 s. 

The BAT position is
RA, Dec = 234.4744, +63.3387 deg which is
   RA(J2000)  = 15h 37m 53.9s
   Dec(J2000) = +63d 20′ 19.3″
with an estimated uncertainty of 3 arcmin radius.
