Details:
Magnetic storms are great, but even when everything is at rest at Kp.0-1 local K 0 my measurements are sometimes very interesting. Like today, almost a tight line on the graph, but by paying close attention and zooming in, sometimes pulsating signals appear upwards. This is very striking, there are Pc 3 waves on which Pc 1-2 waves are superimposed. In musical terms a form of vibrato modulation. It's a pity that all this takes place at frequencies that are too low for us, but I'm going to find a way to use this to control synthesizers for example.
