At 18:34:10 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 100401 ***A*** (trigger=418109). Swift slewed immediately to the burst.
The BAT on-board calculated location is
RA, Dec 70.262, +44.512 which is
RA(J2000) = 04h 41m 03s
Dec(J2000) = +44d 30' 44"
with an uncertainty of 3 arcmin (radius, 90% containment, including
systematic uncertainty). The BAT light curve showed a [**double-peaked**]
structure with a duration of about TTT sec. The peak count rate
was ~0 counts/sec (15-350 keV), at ~ sec after the trigger.
