Reported on http://spacweather.com
A minor CME expected to hit Earth's magnetic field on Sept. 17th apparently
did not. Either it sailed wide of our planet or its impact was too puny to
detect. With no CME to rattle Earth's magnetic field, NOAA forecasters have
downgraded the chances of a geomagnetic storm today to only 20%.

Possibly Northern Lights
From http://spaceweather.com :
'INCOMING CME: Another CME is en route to Earth. It was launched in our
direction four days ago by the eruption of a magnetic filament near the
center of the solar disk.
The impact won't be as effective as the double-blow Earth experienced on
Sept. 12th, when two CMEs hit in less than 24 hours. Nevertheless, NOAA
forecasters estimate a 50% chance of polar geomagnetic storms on Sept. 17th
when the CME arrives. (Note: Yesterday we wrote that the CME would arrive on
Sept. 16th, however, a revised analysis of its speed suggests a later
arrival.) High-latitude sky watchers should be alert for auroras.'
