JUPITER-MOON CONJUNCTION: When the sun goes down tonight, step outside and look up. The crescent Moon and Jupiter are having a close encounter in the constellation Taurus - and don't forget Comet Pan-STARRS near the western horizon: sky map.
STRONG CME IMPACT: As predicted, a coronal mass ejection (CME) hit Earth's magnetic field at 0600 UT on March 17th. The impact lifted the solar wind speed from 300 km/s to 700 km/s and sparked a moderately strong (Kp=6) geomagnetic storm. Northern Lights spilled across the Canadian border into the United States as far south as Colorado:

"Just after 4 am local time, the skies turned green and red behind the twin stone monoliths of Rabbit Ears Peak near Steamboat Springs, Colorado," reports photographer and astronomy professsor Jimmy Westlake.
In the contiguous United States, auroras also appeared above New York, Washington, Minnesota, Wisconsin, Wyoming, Michigan and the Dakotas. Scan the realtime photo gallery and count the states.
The show's not over. Geomagnetic storming is underway as Earth passes through the wake of the CME. High-latitude sky watchers should remain alert for auroras. www.spaceweather.com
