"CASSINI CAUGHT IN HYPERION'S ELECTRON BEAM"
Some highlights:The new analysis of the data shows that Cassini was magnetically connected to the surface of Hyperion for a brief period, which enabled it to be bathed in a beam of electrons coming from the moon's surface.The Cassini data show that a similar process can take place on Hyperion. Due to its interaction with solar UV light and charged particles from Saturn's magnetosphere, the moon's surface may acquire a net electric charge. This is precisely what was found by Cassini's instruments.Analysis of the CAPS-ELS data indicates that it remotely detected a strongly negative surface potential (-200 volts) on Hyperion, consistent with the predicted electrostatic charge in regions near the moon's terminator – the day-night boundary."The large difference in potential between the surface and the spacecraft resulted in a flow of electrons being accelerated from Hyperion toward Cassini," said Tom Nordheim. "It was rather like Cassini receiving a 200 volt electric shock from Hyperion, even though they were over 2000 km apart at the time."
And the beginning of that connect-the-dots moment:"Our observations show that this is also an important effect at outer planet moons and that we need to take this into account when studying how these moons interact with their environment."

I have no trouble believing there's a connection between solar and even cosmic events, and planetary weather.
3) A fraction of the current enters the Corona at the poles.
4) Only a fixed amount of that fraction reaches the Sun's surface, causing arc discharge.
3) The rest flows out over the equatorial current sheet.)
