Oumuamua observation

Thank you for all the stuff to ponder about. It makes me wish we could have a breakthrough for farming and global warming water levels by weather control.

im not sure what to think of whistlers I am fascinated with the new term and possible ideas it might spark. Radiation belts I did not know exist. I wonder why the radiation belt exist and not a zone. Due to the emf frequency?

Above the thunderstorm is a portion of the ionosphere. When a lightning strike occurs it induces a current in the ionosphere. That current echoes back and forth in the magnetic field as it bounces pole to pole.
In electrical engineering it is well known that the magnitude of an induced current is proportional to the rate of change of the inducing current. This is why using an AC voltage transformer on DC won't work. In the case of lightning, the rate of change is very high, with a rise time of around 10 microseconds. Such a short rise time involving such a large current (100,000 amperes) is sufficient to induce a current 100 miles away.
A volcanic eruption has too long a rise time. Any other terrestrial phenomena than lightning is too slow.
