THE DIURNAL PERIODICITY OF AURORA WITHIN THE MAXIMUM-FREQUENCY ZONE
Three types of auroral diurnal variations are defined. The first and most simple type, having a single night maximum, is observed in the outer zone, that is, up to about 70 degrees of geomagnetic latitude. The second and more complicated type, exhibiting a secondary morning maximum, prevails in the...
