Remarkable fluctuations on my ground current instruments on October 24, 2020 early in the morning.
Fluctuations can also be seen on the declination magnetogram from Abisko,data from intermagnet.org and Tromso Geophysical observatory.
Small induced current variations very clearly visible on my instruments, both on N-S and E-W measurement.
I know nothing about the mechanism behind these pulses and it is well beyond the range of the Pc1 to Pc5 Pulsating continuous waves.
Maybe it's a coincidence.
It is also my first observation of this very low frequency phenomenon
