CME IMPACT: As predicted, a CME hit Earth's magnetic field on Jan. 9th
(20:00 UT). The impact was weaker than expected, however, and it
failed to produce widespread geomagnetic storms. Nevertheless, some
beautiful auroras appeared around the Arctic Circle. Harald Albrigtsen
sends this picture from Tromsø, Norway:

It was dark in Norway when the CME arrived, so observers there
witnessed a nice display. By the time night fell over North America,
however, the lights had faded. US observers saw nothing remarkable.

More auroras are possible on Jan. 10th as Earth passes through the
magnetic wake of the CME. NOAA forecasters estimate a 85% chance of
polar geomagnetic storms before the day is over. Aurora alerts: text,
voice.
