DOUBLE SOLAR ECLIPSE: Yesterday, a NASA spacecraft witnessed a rare
double eclipse. The Solar Dynamics Observatory photographed Earth and
the Moon passing in front of the sun at the same time. Photos are
highlighted on today's edition of http://spaceweather.com.
AURORA SEASON BEGINS: For reasons researchers still don't fully
understand, auroras love equinoxes. At this time of year even gentle
gusts of solar wind can spark a nice display of Northern or Southern
Lights. Such an event is about to occur. A stream of solar wind is
expected to hit Earth's magnetic field on Sept. 14-15. Aurora alerts are available from http://spaceweathertext.com (text) and http://spaceweatherphone.com (voice).
