Stamatikos (OSU), T. N. Ukwatta (LANL)\n(i.e. the Swift-BAT team):\n\nUsing the data set from T-239 to T+963 sec from the recent telemetry downlink,\nwe report further analysis of BAT GRB 180410A (trigger #824063)\n(Gropp et al., GCN Circ. 22620).  The BAT ground-calculated position is\nRA, Dec = 95.974, 12.804 deg which is\n  RA(J2000)  =  06h 23m 53.7s\n  Dec(J2000) = +12d 48' 15.2\"\nwith an uncertainty of 1.9 arcmin, (radius, sys+stat, 90% containment).\nThe partial coding was 53%.\n\nThe mask-weighted light curve shows a weak-long pulse that starts and peak\nat ~ T+25 s, and ends at ~T+150 s. T90 (15-350 keV) is 100.7 +- 13.8 sec\n(estimated error including systematics).\n\nThe time-averaged spectrum from T+25.16 to T+153.67 sec is best fit by a simple\npower-law model.  The power law index of the time-averaged spectrum is\n1.46 +- 0.13.  The fluence in the 15-150 keV band is 2.2 +- 0.2 x 10^-6 erg/cm2.\nThe 1-sec peak photon flux measured from T+25.70 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 spectral and temporal behaviors are consistent with those of a GRB. However,\ndue to the proximity to the Galactic plane (0.17 degrees), we cannot rule out the\npossibility that this is a Galactic transient.\n\nThe results of the batgrbproduct analysis are available at\nhttp://gcn.gsfc.nasa.gov/notices_s/824063/BA/",
