(i.e. the Swift-BAT team):
 
Using the data set from T-60 to T+303 sec from recent telemetry downlinks,
we report that trigger #652046 is due to a particle shower event in BAT.
There were 118 photons and/or particles in a single 100 microsec timestamp interval.
This trigger is not anything astrophysical.
