Have you heard of an event to come called the solar flash?

I've heard of solar flares, they are coronal mass ejections from the sun that can cause disruption in the magnetic field around the earth. They are rarely bad but can cause a lot of disruption if they are strong and come directly towards us.

Are you referring to the green flash at the point the sun drops below the horizon at sundown? I saw it once, while on an African Safari in the Serengeti.
