SIERRA FIREBALL DECODED: An explosion over California that rattled homes
across at least two states on Sunday, April 22nd, has been analyzed by
NASA's Meteoroid Environment Office: It was a natural meteoroid the
size of a mini-van. Analysts say the space rock exploded in the
atmosphere with an energy equal to nearly 4 kilotons of TNT and might
have sprayed the Sierra Nevada mountains with meteorites. Visit http://spaceweather.com for more information.
AURORA WATCH: At the time this alert is being written on April 23rd, a
minor geomagnetic storm is underway. The storm is likely due to Earth's
passage through the wake of a CME that swept past our planet earlier in
the day. Sign up for aurora alerts at http://spaceweathertext.com (text) or http://spaceweatherphone.com (voice).
