GEOMAGNETIC AND IONOSPHERIC OBSERVATIONS ASSOCIATED WITH AURORAL ACTIVITY DURING THE TOTAL SOLAR ECLIPSE OF JULY 20, 1963

Data obtained at Fort Providence, N.W.T., Canada, during the total solar eclipse of July 20, 1963, indicate that during most of the partial eclipse there was a moderate degree of auroral activity. This activity became slight during the period of totality and no auroral luminosity was detected. Elect...

Description
Summary:Data obtained at Fort Providence, N.W.T., Canada, during the total solar eclipse of July 20, 1963, indicate that during most of the partial eclipse there was a moderate degree of auroral activity. This activity became slight during the period of totality and no auroral luminosity was detected. Electron precipitation was indicated by an enhancement of the intensity of X rays of energy greater than 9 keV at balloon altitudes and by small amounts of cosmic-noise absorption. A small but irregular increase in cosmic-noise level at 30 Mc/s, which was greater than 0.2 dB at totality, was recorded. It was concluded that the irregularity was caused by small amounts of superimposed auroral absorption.
