Using the data set from T-240 to T+962 sec from the recent telemetry downlink,
we report further analysis of BAT GRB 110829***A*** (trigger #501752)
(NAME, et al., GCN Circ. xxxx).  The BAT ground-calculated position is
RA, Dec = 278.710, -8.770 deg which is 
   RA(J2000)  =  18h 34m 50.3s 
   Dec(J2000) = -08d 46' 11.6" 
with an uncertainty of 3.1 arcmin, (radius, sys+stat, 90% containment).
The partial coding was 57%.
 
[Description about the mask-weighted light curve]
T90 (15-350 keV) is 0.01 +- 0.01 sec (estimated error including systematics).
 
The time-averaged spectrum from T+0.00 to T+0.01 sec is best fit by a blackbody
model.  The blackbody temperature is 9.19 +- 1.54 keV.  The fluence in the 15-150 keV
band is 5.6 +- 2.6 x 10^-09 erg/cm2.  The 1-sec peak photon flux measured
from T-0.49 sec in the 15-150 keV band is 0.31 +- 0.19 ph/cm2/sec.
All the quoted errors are at the 90% confidence level.
