[meteorite-list] Solar flares (ot) ? or are ions meteorites?

[Chris Peterson]

Our Sun isn't active enough to produce flares large enough to 
dangerously irradiate the Earth. If it were, given hundreds of millions 
of years of land-based life, we almost certainly wouldn't be here.

Keep in mind that those CMEs that look so impressive in the videos 
produce a particle density at the Earth that represents a harder vacuum 
than can be achieved in a lab, and what's left is effectively blocked by 
our magnetic field and atmosphere.

Other stars are more active, and ours may become so billions of years 
from now. But at the moment, we're safe (assuming we can recover from 
having our power grids or satellites knocked out... which are very 
possible consequences of flares that we know the Sun can produce).
