Sound from two high-altitude explosions at the White Sands Missile Range, New Mexico, was detected by a surface-based microphone array located about 30 miles to the south of the explosions. The observed azimuth angles of the sounds as they crossed the array were 1 deg 8 min and 1 deg 35 min west of the geographical azimuth between sound source and microphone array. This error was due to easterly winds, and a correction for these winds was determined which reduced the error to 0 deg 5 min and 0 deg 12 min.
