Aurora season begins, NLC season ends

Space Weather News for Aug. 31, 2014

Aurora season is now fully underway around the Arctic circle. With
the end of northern summer approaching, dancing green lights are
beaming through the deepening polar twilight on a regular basis.
Unlike lower latitudes, the Arctic does not require a full-fledged
geomagnetic storm for aurora sightings. Check the latest images on
the front page of

Meanwhile, another polar phenomenon is on the wane: noctilucent clouds
(NLCs). Data from NASA's AIM spacecraft suggest that the northern
summer season for NLCs ended on or about August 26th. The
"noctilucent daisy" shown on will probably
remain blank until November, when NLC activity shifts to the southern
hemisphere. NLCs are a summertime phenomenon and they switch back and
forth between the hemispheres accordingly. Stay tuned for more
electric blue ... in a few months.
