Tueller (GSFC),\n(i.e. the Swift-BAT team):\n \nUsing the data set from T-239 to T+886 sec from recent telemetry downlinks,\nwe report further analysis of BAT GRB 140301A (trigger #589590)\n(Page, et al., GCN Circ. 15896).  The BAT ground-calculated position is\nRA, Dec = 69.521, -34.249 deg, which is \n   RA(J2000)  =  04h 38m 05.0s \n   Dec(J2000) = -34d 14' 56.8\" \nwith an uncertainty of 1.9 arcmin, (radius, sys+stat, 90% containment).\nThe partial coding was 66%.\n \nThe mask-weighted light curve shows a roughly symmetric peak starting\nat ~T-15 sec, peaking at ~T+1 sec, and ending at ~T+20 sec.\nT90 (15-350 keV) is 31.0 +- 5.7 sec (estimated error including systematics).\n \nThe time-averaged spectrum from T-13.18 to T+22.82 sec is best fit by a simple\npower-law model.  The power law index of the time-averaged spectrum is\n1.96 +- 0.28.  The fluence in the 15-150 keV band is 4.4 +- 0.8 x 10^-7 erg/cm2.\nThe 1-sec peak photon flux measured from T+0.82 sec in the 15-150 keV band\nis 0.7 +- 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/589590/BA/",
