A. P. Beardmore (U Leicester), C. Guidorzi (U Ferrara),
A. Y. Lien (NASA/GSFC/ORAU), K. L. Page (U Leicester) and
D. M. Palmer (LANL) report on behalf of the Swift Team:

At 09:11:22 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 120212A (trigger=514709).  Swift slewed to the burst location
at T+44 min due to an Earth limb observing constraint.
The BAT on-board calculated location is 
RA, Dec 43.105, -18.025 which is 
   RA(J2000) = 02h 52m 25s
   Dec(J2000) = -18d 01' 29"
with an uncertainty of 3 arcmin (radius, 90% containment, including 
systematic uncertainty).  The BAT light curve showed a single-peaked
structure with a duration of about 8 sec.  The peak count rate
was ~1600 counts/sec (15-350 keV), at ~0 sec after the trigger. 

Due to an observing constraint, Swift will not slew until T0+44.6
minutes. There will be no XRT or UVOT data until this time. 

Burst Advocate for this burst is E. Sonbas (edasonbas AT yahoo.com). 
Please contact the BA by email if you require additional information
regarding Swift followup of this burst. In extremely urgent cases, after
trying the Burst Advocate, you can contact the Swift PI by phone (see
Swift TOO web site for information: http://www.swift.psu.edu/too.html.)

[GCN OPS NOTE(12feb12): Per author's request, the auto-generated
"slewed immediately" sentence was corrected to reflect the delayed slew.]
