CME WIPES OUT COSMIC RAYS
CME WIPES OUT COSMIC RAYS:
A CME that hit Earth's magnetic field on March 13th did more than spark
bright auroras. It also wiped out a lot of cosmic rays. The storm cloud
literally pushed space radiation away from our planet. The effect,
called a "Forbush decrease," is still underway 4 days later. Full story @
