Palmer (LANL), T. Sakamoto (AGU),\nM. H. Siegel (PSU), M. Stamatikos (OSU), J. Tueller (GSFC), T. N. Ukwatta (MSU)\n(i.e. the Swift-BAT team):\n \nUsing the data set from T-152 to T+963 sec from the recent telemetry downlink,\nwe report further analysis of BAT GRB 140430A (trigger #597722)\n(Siegel, et al., GCN Circ. 16190).  The BAT ground-calculated position is\nRA, Dec = 102.942, 23.033 deg, which is \n   RA(J2000)  =  06h 51m 46.0s \n   Dec(J2000) = +23d 01' 58.2\" \nwith an uncertainty of 1.0 arcmin, (radius, sys+stat, 90% containment).\nThe partial coding was 100%.\n \nThe mask-weighted light curve shows several well separated peaks.\nThe first (and brightest) starts at ~T-1 sec, peaks at ~T+4 sec,\nand ends at ~T+9 sec.  The 2nd and 3rd peaks peak at ~T+30 and ~T+180,\nrespectively.  T90 (15-350 keV) is 173.6 +- 3.7 sec (estimated error\nincluding systematics).\n \nThe time-averaged spectrum from T-0.30 to T+177.58 sec is best fit by a simple\npower-law model.  The power law index of the time-averaged spectrum is\n2.00 +- 0.22.  The fluence in the 15-150 keV band is 1.1 +- 0.2 x 10^-6 erg/cm2.\nThe 1-sec peak photon flux measured from T+2.44 sec in the 15-150 keV band\nis 2.5 +- 0.2 ph/cm2/sec.  All the quoted errors are at the 90% confidence\nlevel. \n \nThe results of the batgrbproduct analysis are available at\nhttp://gcn.gsfc.nasa.gov/notices_s/597722/BA/",
