Observations of the 1963 July 20 solar eclipse. I Spectroscopic separation of the F K components of the solar corona at large distances from the Sun
Abstract
Photoelectric observations were made of the total solar eclipse of 1963 July 20 from an aircraft at an altitude of 30 000 ft. Data are presented for the absolute brightness of the solar corona and for the relative depth of the Ha absorption line in the spectrum of the corona to a distance of I 6R0 the line depth was measured using interference fflters. A separation of the F and K components based on tbe line depth measurements is given to I6 from the Sun.
