Sakamoto (GSFC/UMBC)\non behalf of the Swift-BAT team:\n\nWe report further results of BAT observations of GRB 101225A (Racusin, et al.,\nGCN Circ. 11493).\n\nThe most intense emission observed by BAT from GRB 101225A in the 14-50 keV range\noccurred from T+1372 to T+1672 seconds, later than previously reported (Palmer,\net al. GCN circ #11500).  The source was not in the BAT field of view from T-4500\nto T-100 sec, from T+1088 to T+1372 sec, and from T+1758 to T+4936 sec.  There was\nno detectable emission prior to T-4500 sec, and the burst appears to have started\nsometime before the source entered the BAT field of view at T-100 sec.\n\nThe spectrum from T+1372 to T+1672 seconds is similar to the earlier report, with\na single power law photon index of 1.87 +- 0.21.  The total fluence was greater,\npossibly much greater, than 3 x 10^-6 ergs/cm^2 or about 1.6 times the fluence\nreported earlier.\n\nBAT detection of extremely long emission is similar to that of GRB 060218 and\nGRB 100316D (both spectroscopically confirmed SN-GRBs).",
