COMMENTS: This is an image trigger. (The RATE_SIGNIF & BKG_{INTEN, TIME, DUR} are undefined.)
COMMENTS: A point_source was found.
COMMENTS: This is a low-flux event whose position matches one of the nearby galaxy sources in the on-board catalog!
COMMENTS: This matches a source in the on-board catalog: Num=12171=NGC1023, delta=0.084 [deg].
COMMENTS: This matches a source in the ground catalog: NGC1023, delta=0.084 [deg].
COMMENTS: The position is inside the galaxy NGC1023 (of total mag=9.50 and dia=8.70 arcmin).

At 13:37:25 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 170107 ***A*** (trigger=730874). Swift slewed immediately to the burst.
The BAT on-board calculated location is
RA, Dec 40.038, +39.132 which is
RA(J2000) = 02h 40m 09s
Dec(J2000) = +39d 07' 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 ~1414 counts/sec (15-350 keV), at ~7 sec after the trigger.
