APOD: 2003 October 30 - Aurora in Colorado Skies
Vividauroral displays were triggered by a cloud of high energyparticles and magnetic fields from the Sun that collided with planet Earth'smagnetosphere yesterday, October 29, at about 06:30 Universal Time .The collision was anticipated, following an intensesolar flare and coronal mass ejection detected on October 28, and manyanxious skywatchers were rewarded with an enjoyable light show.While aurorae don't normally haunt skies in the southern UnitedStates, they were reported from locations in Missouri, Texas,New Mexico, and California in the early morning hours.Near Yampa, Colorado astronomer Jimmy Westlake also spentearly yesterday morning enjoying the stormy space weather .He was impressed by this colorful apparition ofthe northern lights -- produced byoxygen and nitrogen atoms excited by collisions withenergetic particles from the magnetosphere andreturning to lower energy states,at altitudes of 100 kilometers or more.Brighter stars shine through the extreme high-altitudeglow wh ...

Explanation: What causes black aurora? These gaps in normal bright aurora are frequently recorded but rarely questioned. Recent research using data from four Cluster spacecraft orbiting the Earth has now likely found the secret: black auroras are actually anti-auroras. In normal auroras , electrons and/or predominantly negatively charged particles fall toward Earth along surfaces of constant magnetic field . They ionize the Earth's atmosphere on impact, causing the bright glows. In black anti-auroras, however, negatively charged particles are sucked out from the Earth's ionosphere along adjoining magnetic field lines. These dark anti-auroras can climb to over 20,000 kilometers and last for several minutes. Pictured above , a black aurora is seen dividing bright auroras over Fairbanks, Alaska , USA . ...

APOD: 2003 August 9 - A Perseid Aurora
A Perseid Aurora ... Explanation: Just after the Moon set but before the Sun rose in the early morning hours of 2000 August 12, meteors pelted the Earth from the direction of the constellation Perseus , while ions pelted the Earth from the Sun . The meteors were expected as sub-sand grains long left behind by Comet Swift-Tuttle annually create the Perseids Meteor Shower . The aurorae were unexpected, however, as electrons , protons , and heavier ions raced out from a large Coronal Mass Ejection that had occurred just days before on the Sun. In the foreground is Hahn's Peak, an extinct volcano in Colorado , USA .The Perseid meteor shower peaks this year over the next few days, with as much as one bright meteor per minute visible from some locations. ...

S. Buttnor: "What a great display here! For six hours we had auroral activity somewhere in the sky, and often almost everywhere. Virtually every kind of auroral structure was seen, and the colors were lovely. Photos: . Camera: Canon Powershot A70." ... Summary : It's n orthern autumn and that means it's aurora season . The auroras on this page were triggered by a coronal mass ejection hitting Earth on Oct. 29th. The CME was hurled into space by one of the most powerful solar explosions in years--an X17-class flare from giant sunspot 486. ... [Read More]
