We present infrasonic observations of the recent high explosive test, Watusi, performed at the Nevada Test Site on 9/28/02 at 21:25:17 UT, with an equivalent yield of 38,000 lbs of TNT. Data were collected from four infrasound arrays at distances from 44 km to 883 km from the event. Various aspects of the analysis from each array will be discussed. Finally the Watusi data will be compared with our results from other high explosive tests.
