At 00:56:30 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 260101 ***A*** (trigger=1429608). Swift slewed immediately to the burst.
The BAT on-board calculated location is
RA, Dec 86.465, +63.568 which is
RA(J2000) = 05h 45m 51s
Dec(J2000) = +63d 34' 06"
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 ~7486 counts/sec (15-350 keV), at ~25 sec after the trigger.
