Using the partial data set from T-60 to T+123 sec from recent telemetry
downlinks, we report further analysis of BAT GRB 060219 (trigger #191512)
(Moretti, et al., GCN 4788).  The BAT ground-calculated position is
RA,Dec = 241.815,+32.310 deg {16h 07m 15.5s,+32d 18' 37.7"} (J2000)
+- 2.5 arcmin, (radius, sys+stat, 90% containment).  The partial coding is 67%.
Using this partial data download, there is pre-trigger emission starting before T-60 sec.
After the trigger pulse from T+2 to T+10 sec, there is a weak 10-sec wide pulse
at T+50 sec, and then nothing out to the T+123 sec limit on the currently available data.
