Abstract

The variations of the midday critical frequency of the F2-layer, ƒ0F2, with the phase of the moon are computed for eighteen stations within about ±40° latitude during a period of low sunspot activity. The results show that the phase of the lunar variation of ƒ0F2 is determined by the magnetic and not by the geomagnetic or the geographic latitude. The reversal from the equatorial type of variation with a maximum near 04 lunar hour to the higher latitude type with a maximum near 10 lunar hour occurs at about ±11° magnetic latitude. The variation of amplitude with latitude shows a sharp maximum on the magnetic equator, associated with the equatorial electro-jet, and two broad maxima at about ±20° magnetic latitude. The latter are closely associated with the well-known maxima in the variation of noon ƒ0F2 with latitude.
