Vetere (ASDC)\non behalf of the Swift-BAT team:\n\nUsing the full data set from recent telemetry downlinks, we report\nfurther analysis of Swift-BAT detection of SGR 1900+14 (trigger #202746)\n(Vetere, et al., GCN 4922).  T90 is 48 +- 4 msec.  The partial coding\nfraction is 33%.  The lightcurve is a single FRED-like peak wih a decay\nof ~16 msec.  The BAT spectrum is well fitted with a blackbody model:\nkT = 17.5 -7.9,+15.7 keV (90% confidence).  The reduced chi-squared\nis 0.95 for 57 degrees of freedom.  The spectral parameters are consistent\nwith the HETE-2 observation of the 2001 middle-class burst of SGR 1900 \n(see Fig.5 of Olive et al. ApJ 616 (2004) 1148 (astro-ph/0403162)).\n\nThere are 4 other BAT detections from this source (two before the \noriginal triggered detection, and two after):\n   Date       Time       Comment\n   2006-03-25 10:12:05   Roughly 4 times brighter than the 20:16:40 outburst\n   2006-03-25 18:07:21   Roughly 2 times brighter than the 20:16:40 outburst\n   2006-03-25 20:16:40   Triggered detection\n   2006-03-25 23:34:08   Comparable to 20:16:40 in brightness\n   2006-03-26 00:59:23   Comparable to 20:16:40 in brightness\n\nWe note that the 4th & 5th events occurred during TOO follow-up observations\nof the SGR 1900+14 source.",
