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.

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.
