Zusammenfassung |
In a set of balloon flights in the Brazilian
magnetic anomaly region (BMAr) short time periodic variations were observed,
i.e. pulsation, of secondary charged and neutral particle fluxes, X- and
<gamma>-ray fluxes with amplitudes of about 2–4%. The pulsations are
accompanied by the geomagnetic Pc4 pulsations and have similar periodicity. The
phenomenon was observed over various local times and in quiet and disturbed
magnetospheric conditions. One of the explanations of this effect, i.e. periodic
variation of local cut-off rigidity, and following pulsations of primary and
secondary cosmic ray intensity is suggested. |
