Scientific paper
A multipoint case study approach is used to delineate significant morphological differences between, and distinct sources for, two kinds of high-latitude dayside ULF wave activity in the Pc 3 to Pi 1 frequency range. Evidence is presented that narrow-band Pc 3-4 pulsations appear roughly simultaneously at widely spaced locations in the dayside magnetosphere and polar cap and that their occurrence/intensity is controlled by the cone angle of the IMF, while broadband Pi 1 type activity appears to be related closely to precipitation of energetic plasma sheet electrons, hence more localized ionospheric activity. Additional evidence is provided that the cusp/cleft regions play a significant part in the transmission to low altitudes of at least some of the wave energy of solar wind-controlled pulsations.
