From: Nighttime Pc3 pulsations: MM100 and MAGDAS observations
Averaged variations of Pc3 parameters from night to morning hours at BEL and KAT stations (\(L\approx 2\)). Pc3 occurrence rate P is given at the upper panel, day-night spectral coherence is given at the middle pair, and BEL/KAT (night to day) PSD ratio are given at the bottom panel. Solid/dashed lines show the results for the night position of both footprints (nn)/ dayside position of one of footprints (nd). Northern summer/winter are shown with warm/cold colors
