Radio Echo Observations of Meteor Activity in the Southern Hemisphere

Abstract

A further analysis has been made of 32,000 meteor echoes obtained during 1953 by radar apparatus operating at a frequency of 69 Mc/s. Monthly and annual mean diurnal rate curves have been drawn, revealing a strong similarity between southern and northern hemisphere results. It is concluded that most meteoric matter incident on the southern hemisphere, down to magnitude +4·5, is confined to direct orbits closely following the plane of the ecliptic.
