Project 6.3 - Effect BY Atomic Explosions on the Ionosphere - M, Hawn
Ob jective
The objective of Project 6.3 is to obtain data on the effects of
high yield nuclear explosions on the Ionosphere,
Principally, to in-
vestigate the area of absorption, probably due tothe high altitude
radioactive particles, and to study the effects of orientation relative
to the earth's magnetic field on F2 layer effects,
Instrumentation
The system comprises:
*
Two Ionosphere recorders, type C-2, operating on pulse transmission, installed in 6 ton trailer vans, one located at Rongerik Atoll
and one located at Kusaie in the Caroline Islands,
One Ionosphere recorder, Type C-3, operating on pulse trans-
mission, installed in a C-97 airplane.
This station operated on the
ground at Kwajalein.
Preliminary Results:
All stations operated successfully during this test.
&97:
The C~97? was grounded on Kwajalein while a new engine was being
installed.
Ground records were taken,
The only apparent effects occe-
urred between plus twenty and plus forty minutes, during which time part
of the F layer shifted in height, and new reflections appeared,
