CME SWEEPS ASIDE COSMIC RAYS: On July 16th, a CME hit Earth's magnetic field, sparking two days of geomagnetic storms and beautiful auroras. The solar storm cloud also swept aside some of the cosmic rays currently surrounding our planet. A sudden decrease in deep space radiation was detected by a global network of neutron monitors as well as a space weather balloon in the stratosphere over California. Almost a week later, cosmic rays are finally returning to normal. Learn more about this event on today's edition of Spaceweather.com.
