[19] A few conclusions follow from the analysis and comparison of simultaneous observation of geomagnetic pulsations in two frequency ranges (7.0-22.0 mHz and 0.5-2.0 Hz):
[20] 1. In 70% of giant pulsation recorded at auroral and middle latitudes are observed against a background of global excitation of the geomagnetic pulsations in the Pc1 band (“pearl” series).
[21] 2. The Pg pulsation period ( T ) is linearly related to the repetition period of "pearls" ( t ), the ratio ( T/t ) being proportional to the value of Dst variation.
[22] 3. The detected interrelation between Pg pulsation and
"pearls" is an indirect experimental confirmation of the fact
that the protons with energies
0-80 keV injected into the
magnetosphere at the nightside and drifting westward to the
dayside participate in generation of Pg.
