Using the data set from T-239 to T+963 sec from the recent telemetry downlink,
we report further analysis of BAT GRB 140916***A*** (trigger #612804)
(NAME, et al., GCN Circ. xxxx).  The BAT ground-calculated position is
RA, Dec = 40.382, -39.692 deg which is 
   RA(J2000)  =  02h 41m 31.6s 
   Dec(J2000) = -39d 41' 29.9" 
with an uncertainty of 2.6 arcmin, (radius, sys+stat, 90% containment).
The partial coding was 16%.
 
[Description about the mask-weighted light curve]
T90 (15-350 keV) is 69.0 +- 9.5 sec (estimated error including systematics).
 
The time-averaged spectrum from T-0.9 to T+79.1 sec is best fit by a simple
power-law model.  The power law index of the time-averaged spectrum is
2.14 +- 0.29.  The fluence in the 15-150 keV band is 1.5 +- 0.3 x 10^-06 erg/cm2.
The 1-sec peak photon flux measured from T+1.80 sec in the 15-150 keV band
is 1.4 +- 0.4 ph/cm2/sec.  All the quoted errors are at the 90% confidence
level.
