Barnes BURST POSITION The position of burst was determined by triangulation utilizing four phototheodolite plates, two each from Pifarii (WILMA) and Mack photo stations. Ground Zero was: N 102851 #¢ 50 E 126647 # 50 Ground Zero is therefore about 190 feet at an Azimuth of 224,° 21! from imtended Ground Zero, Burst altitude was 680 # 35 feet. TIME OF FALL Time of fall was determined to be 32.185 seconds. FIREBALL YIELDS Fireball yields have been determined from four films, one each from Parry (EIMER), Mack, Piiarii (WIIMA), and Runit (YVONNE), with the following results: Parry Mack Pilarii “hy | 2D Runit rt Therefore, the fireball yield is EE Preliminary measurements indicate an alpha or Mmmm7p Four Bhangmeters at the contpol point gave time-to-minimmTee ¥ :3 COPIED/DU.
