At 03:36:32 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 130211 ***A*** (trigger=548276). Swift slewed immediately to the burst.
The BAT on-board calculated location is
RA, Dec 147.523, -42.339 which is
RA(J2000) = 09h 50m 05s
Dec(J2000) = -42d 20' 18"
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 ~1320 counts/sec (15-350 keV), at ~1 sec after the trigger.
