Using the data set from T-239 to T+963 sec from the recent telemetry downlink,
we report further analysis of BAT GRB 080212***A*** (trigger #303105)
(NAME, et al., GCN Circ. xxxx).  The BAT ground-calculated position is
RA, Dec = 231.145, -22.738 deg which is 
   RA(J2000)  =  15h 24m 34.8s 
   Dec(J2000) = -22d 44' 15.4" 
with an uncertainty of 1.5 arcmin, (radius, sys+stat, 90% containment).
The partial coding was 35%.
 
[Description about the mask-weighted light curve]
T90 (15-350 keV) is 126.3 +- 13.2 sec (estimated error including systematics).
 
The time-averaged spectrum from T-62.2 to T+78.1 sec is best fit by a power law
with an exponential cutoff.  This fit gives a photon index 0.23 +- 0.60, 
and Epeak of 69.9 +- 13.1 keV (chi squared 60.46 for 56 d.o.f.).  For this
model the total fluence in the 15-150 keV band is 3.0 +- 0.3 x 10^-06 erg/cm2
and the 1-sec peak flux measured from T+3.78 sec in the 15-150 keV band is
1.1 +- 0.3 ph/cm2/sec.  A fit to a simple power law gives a photon index
of 1.51 +- 0.11 (chi squared 78.63 for 57 d.o.f.).  All the quoted errors
are at the 90% confidence level.
