Cluster formation in Hessdalen lights

Abstract

In this paper we show a mechanism of light ball cluster formation in Hessdalen lights (HL) by the nonlinear interaction of ion-acoustic and dusty-acoustic waves with low frequency geoelectromagnetic waves in dusty plasmas. Our theoretical model shows that the velocity of ejected light balls by HL cluster is of about 104ms−1 in a good agreement with the observed velocity of some ejected light balls, which is estimated as 2×104ms−1.
