on behalf of the Swift-BAT team:

Using a partial data set from recent telemetry downlinks, we report
further analysis of Swift-BAT Trigger #158855 (Marshall, et al., GCN 4069).
So far all we have is data from T-300 to T+32 sec.  The ground-analysis
position is RA,Dec 202.851,+42.101 {13h 31m 24.2s,+42d  6'  4.4"} (J2000)
with an uncertainty of 0.8 arcmin (radius, 90%, stat+sys).  The lightcurve
has two overlapping peaks whose emission starts at T-25.  There are is
a small peak at T+18.  The emission continues beyond T+32 sec.  When we get
the full data set, we will report the standard T90, fluence, and 
peak flux values for this burst.
