Using the data set from T-239 to T+963 sec from the recent telemetry downlink,
we report further analysis of BAT GRB 220708***A*** (trigger #1115156)
(NAME, et al., GCN Circ. xxxx).  The BAT ground-calculated position is
RA, Dec = 103.085, 72.187 deg which is 
   RA(J2000)  =  06h 52m 20.3s 
   Dec(J2000) = +72d 11' 12.7" 
with an uncertainty of 2.2 arcmin, (radius, sys+stat, 90% containment).
The partial coding was 75%.
 
[Description about the mask-weighted light curve]
T90 (15-350 keV) is 4.0 +- 1.4 sec (estimated error including systematics).
 
The time-averaged spectrum from T-1.3 to T+2.7 sec is best fit by a simple
power-law model.  The power law index of the time-averaged spectrum is
2.23 +- 0.32.  The fluence in the 15-150 keV band is 1.2 +- 0.2 x 10^-07 erg/cm2.
The 1-sec peak photon flux measured from T+1.70 sec in the 15-150 keV band
is 0.7 +- 0.2 ph/cm2/sec.  All the quoted errors are at the 90% confidence
level.
