Abstract
As a result of a 69.5 Mc/s radar survey of meteoric activity recently undertaken in New Zealand the variation of incident flux with solar longitude has been determined. It has been confirmed that the spatial density of small-size (sixth magnitude) meteoric matter is greater along the Earth's orbit during the latter half of the year. However the comparison of results from both hemispheres shows that at mid-latitude observing stations this asymmetry has a smaller influence than the gyrations of the ecliptic on the seasonal variation in observed meteor rate. These effects taken together provide a satisfactory explanation for most of the differences between the results from the two hemispheres.
