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:
