Using the data set from T-239 to T+423 sec from the recent telemetry downlink,
we report further analysis of BAT GRB 240302***A*** (trigger #1218293)
(NAME, et al., GCN Circ. xxxx).  The BAT ground-calculated position is
RA, Dec = 245.149, -15.529 deg which is 
   RA(J2000)  =  16h 20m 35.8s 
   Dec(J2000) = -15d 31' 43.4" 
with an uncertainty of 0.0 arcmin, (radius, sys+stat, 90% containment).
The partial coding was 64%.
 
[Description about the mask-weighted light curve]
T90 (15-350 keV) is 5.60 +- 1.41 sec (estimated error including systematics).
 
The time-averaged spectrum from T-233.85 to T-226.63 sec is best fit by a simple
power-law model.  The power law index of the time-averaged spectrum is
1.50 +- 0.00.  The fluence in the 15-150 keV band is 0.0 +- 0.0 x 10^+00 erg/cm2.
The 1-sec peak photon flux measured from T-233.65 sec in the 15-150 keV band
is 0.5 +- 0.2 ph/cm2/sec.  All the quoted errors are at the 90% confidence
level.
