Tueller (GSFC) \non behalf of the Swift-BAT team: \n\nAnalysis of the available data for the Swift-BAT GRB050315 \n(Parsons et al., GCN Circ 3094) yields a fluence of > 2.8x10^-6 \nerg/cm2 in the 15-350 keV band and a peak flux of 2.5 ph/cm2/sec \n(also 15-350 keV).  The photon index of the 1-s peak spectrum (T0+25 sec.) \nis 2.5 +- 0.3 (90% confidence).  Although there is a data gap, \nthe time averaged spectrum also shows a soft spectrum.  \nThis appears to be a soft X-ray-rich GRB.  \n\nWe are planning a further circular when more complete data \nare avaliable.",
