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=25560=(null) (probably an AT_Slot).
COMMENTS: This does not match any source in the ground catalog.
COMMENTS: This is not a GRB.
COMMENTS: This is an interesting source.

At 12:15:46 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 220506 ***A*** (trigger=1105561). Swift slewed immediately to the burst.
The BAT on-board calculated location is
RA, Dec 300.054, +34.874 which is
RA(J2000) = 20h 00m 13s
Dec(J2000) = +34d 52' 28"
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 ~1031 counts/sec (15-350 keV), at ~4 sec after the trigger.
