whether the equator shifts with the
solar cycle, as has been suggested.
Previous measurements, made by
LASL scientists, indicated that the
equator does not shift.
Flights out of Sydney in the
southern wintertime period were
desirable for two reasons:
of
(1) There is a calculated region
continuous
photoelectron
en-
hancement south of Sydney which
represents the nearest equivalent
situation in the Southern Hemis-
phere to that occurring over the
Labrador-Puerto Rico route during
the northern winter. LASL scientists have conducted similar missions over this latter route.

(2) The relative orientation of
magnetic field lines and the sun
permits a systematic survey of conjugate sunlight effects as a function
of latitude with a minimum of
perturbations from other effects
over an area accessible from Sydney.
The plane used in the mission is
a specially-instrumented NC-135
(modified Boeing 707 jet) hown and
maintained for the Atomic Energy
Commission by the U.S. Air Force.
This plane, and two other similar
ones, have been used for several
scientific expeditions in the past
several years. The aircraft are op-
erated out of Kirtland Air Force
Base in Albuquerque.
LASL personnel involved in the
experiment, in addition to Glass,
included Robert W. Peterson, J-16
alternate group leader; Walter P.
Wolff, J-8; Richard L. Wakefield,
J-16; L. Dick Tatro, J-16; John H.
Wolcott, J-16; Lucien M. Black,
J-16; Edward I. Hall, J-8; William
F. Carlson, J-17; Dwight Stephen-
son, J-8 assistant group leader; and
Jim Wells, J-1.
A scientific group from Sandia
Laboratories in Albuquerque also
participated in the mission, conducting a number of experiments
similar to those of LASL'’s.
