At 20:24:21 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 170307 ***A*** (trigger=741528). Swift slewed immediately to the burst.
The BAT on-board calculated location is
RA, Dec 13.535, +9.537 which is
RA(J2000) = 00h 54m 08s
Dec(J2000) = +09d 32' 11"
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 ~8294 counts/sec (15-350 keV), at ~-10 sec after the trigger.
