Ukwatta (GWU)\n(i.e. the Swift-BAT team):\n \nUsing the data set from T-60 to T+243 sec from recent telemetry downlinks,\nwe report further analysis of BAT GRB 120624B (trigger #525068)\n(Vianello, et al., GCN Circ. 13379; Barthelmy, et al., GCN Circ. 13381).  \nThe BAT ground-calculated position is RA, Dec = 170.886, 8.933 deg which is \n\n   RA(J2000)  =  11h 23m 32.6s \n   Dec(J2000) = +08d 56' 00.4\" \n\nwith an uncertainty of 1.0 arcmin, (radius, sys+stat, 90% containment).\nThe partial coding was 86%.\n \nThe mask-weighted light curve shows multiple overlapping episodes starting \nfrom T-25 sec.  There are two main episodes going from T-10 to T+70 sec with a\npeak around T+35 sec, and the second episode starts T+120 sec and appears to \nend around T+200 sec, with peaks at T+140 sec and T+170 sec.  But the data ends \ndue to observing constraint and slewing to a pre-planned target.  T90 (15-350 keV) \nis greater than 192 sec due to the end of the mask-weighted light curve when \nthe source location left the field of view.  \n\nThe time-averaged spectrum from T-15.1 to T+192.8 sec is best fit by a simple\npower-law model.  The power law index of the time-averaged spectrum is\n1.17 +- 0.03.  The fluence in the 15-150 keV band is 2.83 +- 0.04 x 10^-5 erg/cm2.\nThe 1-sec peak photon flux measured from T+138.06 sec in the 15-150 keV band\nis 5.5 +- 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/525068/BA/",
