FIREBALL
A total of four Eastzars, one 15am Fastax and one Mitchell from
Enyu, Aomoen, and Chieerete give an average yield of 3,53 2 0.17 NT.
There was no significent change in yield as seen from the three stations,
Meteorological data vere not available at the time of anelysis
to employ the variable ambient density correction; consequently, an
average density value base? on past observations wad use.
The varietion
in yield due to tensity will not result in a significant yield change,
BRAKCMETER
Six bdhangneters, two aboard the USS Curtiss and four at the nyu
contre] point, operated successfully giving readings of 1¢4 am! 170
millisecormis at the Curtiss and 176, 174, 178, ami 172 aillisecondes
at Exyu. The Nelland Bhangeeter at Enyu control point gave readings
of 165 and 165 ailliseconds for tvo red sensitive oslle, Using the
sealing factor of 0.1 ¢?, the average yieli from bhangneter readings
