At 16:42:23 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 150219 ***A*** (trigger=631747). Swift slewed immediately to the burst.
The BAT on-board calculated location is
RA, Dec 94.300, +9.116 which is
RA(J2000) = 06h 17m 12s
Dec(J2000) = +09d 06' 57"
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 ~3406 counts/sec (15-350 keV), at ~0 sec after the trigger.
