GEOMAGNETIC STORM: Around the Arctic Circle, the longest night of the
year has arrived with perfect timing. A high-speed stream of solar wind
hit Earth's magnetic field on Dec. 21st (the northern winter solstice)
filling the long hours of darkness with Northern Lights. At the time of
this alert, a moderately strong G2-class geomagnetic storm is underway,
and more storms are in the offing. Flowing from a huge hole in the
sun's atmosphere, this solar wind stream is broad. Earth could take
days to cross it.
