    At 10:21:45 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 190129 ***A*** (trigger=886496).  Swift slewed immediately to the burst.
The BAT on-board calculated location is 
RA, Dec 207.026, -63.268 which is 
   RA(J2000) = 13h 48m 06s
   Dec(J2000) = -63d 16' 02"
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 ~1242 counts/sec (15-350 keV), at ~7 sec after the trigger.
