(Geomagnetic prediction according to TESIS)

According to TESIS, there seems to be geomagnetic storm prediction for October 19 as well as the weekend of November 3.

There's many so-called "wild" theories for how geomagnetic storms effect things on Earth, from the stock market prices to human emotions. It's all studies and theories for now from the scientific research papers I've read such as that couple days after geomagnetic storm, the stock prices usually go down from there.

As well, some papers write that human mind also gets irritated or agitated ... so we really don't know much of how magnetism really effects human beings.

What do you think are the effects of geomagnetic storms besides the usual beautiful aurora borealis they create with the Northern Lights?
