Aurora May Drop By Your New Year’s Eve Party

Big sunspot group 2473 cut loose a long-lasting M-class flare earlier today. The explosion produced a fast-moving bubble of plasma directed toward Earth. Plasma, a hot mix of negatively-charged electrons and positively-charged ions (atoms that have lost an electron) may look like a gas but it behaves differently enough to be considered its own state of…

A few more images of the pellet-shaped 2003 SD220 from Arecibo Observatory. Some online reports are suggesting the asteroid could cause earthquakes. Asteroids can't and don't do this, unless a large one happens to hit Earth. This will pass over 6 million miles from us. No worries. Credit: NASA/NSF

Auroral Alert Tonight Dec. 18-19 / Holiday Asteroid Parade

Expect the bee-like swarm of subatomic particles to buzz past the planet and possibly link into out magnetic domain by late afternoon. Minor (G1) storming is expected during the early evening hours over the U.S.…

On October 22 the Sun cut loose with a CME or coronal mass ejection that’s expected to side-swipe the planet. A minor G1 storm is expected to start this afternoon and continue overnight. Because of the moonlight, the…

A coronal mass ejection burst from the sun in the direction of Earth in the early morning of Sept. 18, 2015 that's expected to arrive later this weekend. This photo was taken by the orbiting Solar and Heliospheric Observatory which uses a disk to block the sun (white circle) so it can photograph the solar corona and other activity. Credit: NASA/ESA

Aurora Alert Tonight And Tomorrow Night Sept. 19-20

(UPDATED Sept. 20) A combination of coronal holes, minor CMEs (coronal mass ejections) and a good helping of solar wind shook up Earth’s magnetic environment tonight and will again Sunday night. Minor G1 storm conditions were forecast (Kp=5) for both nights, but in this wee hours this morning (Sept. 20), conditions quickly went from minor to major storm — G1…

Aurora Watch Tonight August 23-24

A different sort of light show visited my corner of the world overnight. Thunderstorms crashed about as rain fell heavily, but 60 miles above the cloud tops, the aurora erupted around 3 in the morning. Those lucky enough to have clear skies along the northern tier of states and Alaska got a great show. Storm…
