COMMENTS: SWIFT-BAT GRB Coordinates.
COMMENTS: This Notice was delayed by more than 60 sec past the end of the trigger integration interval;

COMMENTS: This is an image trigger. (The RATE_SIGNIF & BKG_{INTEN, TIME, DUR} are undefined.)
COMMENTS: A point_source was found.
COMMENTS: This matches a source in the on-board catalog: Num=29542=(null) (probably an AT_Slot).
COMMENTS: This matches a source in the ground catalog: Sco_X-1, delta=0.195 [deg].
COMMENTS: This is not a GRB.
COMMENTS: This is an interesting source.

At 10:37:02 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 240311 ***A*** (trigger=1219543). Swift slewed immediately to the burst.
The BAT on-board calculated location is
RA, Dec 244.853, -15.805 which is
RA(J2000) = 16h 19m 25s
Dec(J2000) = -15d 48' 16"
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.
