Using the data set from T-60 to T+303 sec from the recent telemetry downlink,
we report further analysis of BAT GRB 110118***A*** (trigger #442771)
(NAME, et al., GCN Circ. xxxx).  The BAT ground-calculated position is
RA, Dec = 2.340, -40.979 deg which is 
   RA(J2000)  =  00h 09m 21.5s 
   Dec(J2000) = -40d 58' 44.6" 
with an uncertainty of 4.3 arcmin, (radius, sys+stat, 90% containment).
The partial coding was 87%.
 
[Description about the mask-weighted light curve]
T90 (15-350 keV) is 1.0 +- 0.0 sec (estimated error including systematics).
 
The time-averaged spectrum from T+0.0 to T+1.0 sec is best fit by a simple
power-law model.  The power law index of the time-averaged spectrum is
-1.18 +- 0.95.  The fluence in the 15-150 keV band is 4.0 +- 2.1 x 10^-08 erg/cm2.
The 1-sec peak photon flux measured from T-0.00 sec in the 15-150 keV band
is 0.2 +- 0.1 ph/cm2/sec.  All the quoted errors are at the 90% confidence
level.
