Description
Amongst the characteristics of the solar diurnal anisotropy which can change during the course of one or more solar cycles one can consider the free-space amplitude, the time of maximum (direction of maximum intensity), the rigidity dependence of the amplitude and/or phase and the upper limiting rigidity. Assuming that the rigidity dependence does not change during the solar cycle, it has been found that the freespace amplitude tends to stay approximately constant whilst the upper limiting rigidity Rsub(max) varies. Rsub(max) is relatively high when solar activity is high and is low near sun-spot minimum. (orig./WBU)
Abstract (German)
Unter den Merkmalen der solaren taeglichen Anisotropie, die sich im Verlauf eines oder mehrerer Sonnenzyklen aendern koennen, kann man die Amplitude im freien Raum betrachten, die Zeit des Maximums (Richtung der maximalen Intensitaet), die Haerteabhaengigkeit der Amplitude und/oder der Phase und die obere Grenzhaerte. Unter der Annahme, dass die Haerteabhaengigkeit sich im Sonnenzyklus nicht aendert, hat man herausgefunden, dass die Amplitude im freien Raum etwa konstant bleibt, waehrend die obere Grenzhaerte Rsub(max) variiert. Rsub(max) ist verhaeltnismaessig hoch bei hoher Sonnenaktivitaet und niedrig in der Naehe des Sonnenfleckenminimums. (orig./WBU)Additional details
