Using the data set from T-240 to T+962 sec from the recent telemetry downlink,
we report further analysis of BAT GRB 130617***A*** (trigger #558399)
(NAME, et al., GCN Circ. xxxx).  The BAT ground-calculated position is
RA, Dec = 237.721, -54.301 deg which is 
   RA(J2000)  =  15h 50m 53.1s 
   Dec(J2000) = -54d 18' 02.6" 
with an uncertainty of 1.3 arcmin, (radius, sys+stat, 90% containment).
The partial coding was 87%.
 
[Description about the mask-weighted light curve]
T90 (15-350 keV) is 0.14 +- 0.01 sec (estimated error including systematics).
 
The time-averaged spectrum from T-0.00 to T+0.15 sec fit by a simple
power-law model shows the power law index of 2.16 +- 0.00 (chi squared 138.22 for 57 d.o.f.).
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-0.42 sec in the 15-150 keV band
is 1.4 +- 0.2 ph/cm2/sec.
 
A single blackbody fit to the time-averaged spectrum shows the blackbody
temperature of 11.93 +- 0.75 keV (chi squared 49.46 for 57 d.o.f.).
A thermal bremsstrahlung model fit shows the temperature of 58.31 +- 9.15 keV
(chi squared 97.19 for 57 d.o.f.).  A double blackbody fit shows the lower temperature
of 2.00 +6.50 keV and the higher temperature of 12.13 (error not unconstrained) keV
(chi squared 47.91 for 55 d.o.f.).  All the quoted errors are at the 90% confidence level.
