~Space Weather Update~ CME IMPACT [1]
JUPITER AND THE MOON: The Moon and Jupiter are in conjunction tonight, only a few degrees apart. Look for the bright pair rising in the east a few hours after sunset. [sky map [2]] [photo gallery [3]]
CME IMPACT: A coronal mass ejection hit Earth's magnetic field on Oct. 31st around 1530 UT. The impact [4] jolted [5] Earth's polar magnetic field and sparked auroras around the Arctic Circle. Frank Olsen sends this picture from Sortland, Norway:

For a while, the auroras were bright enough to see despite the glare of the nearly-full Moon. "Conditions were excellent for aurora photography," says Olsen. "I captured the Moon with the Pleiades on top and Jupiter to the left. And just over the mountain, Orion was rising."
NOAA forecasters estimate a 30% to 60% chance of continued geomagnetic activity around the poles during the next 24 hours as reverberations from the CME impact wane. Aurora alerts: text [7], voice [8].
