Posted on 02/08/2012 9:26:49 PM PST by SunkenCiv
Explanation: Have you ever seen an aurora? Auroras are occurring again with increasing frequency. With the Sun being unusually dormant over the past four years, the amount of Sun-induced auroras has been unusually low. More recently, however, our Sun has become increasingly active and exhibiting a greater abundance of sunspots, flares, and coronal mass ejections. Solar activity like this typically expels charged particles into the Solar System, some of which may trigger Earthly auroras. Two weeks ago, beyond trees and before stars, a solar storm precipitated the above timelapse displays of picturesque auroras above Ravnastua, Skoganvarre and Lakselv, Norway. Curtains of auroral light, typically green, flow, shimmer and dance as energetic particles fall toward the Earth and excite air molecules high up in the Earth's atmosphere. With solar maximum still in the future, there may be even better opportunities to see spectacular auroras personally over the next few years.

I once an aurora complete a huge circle.
It was really cool.
That’s a lovely one; thanks.
“Coronal mass ejection” - yep, you drink a mass of Coronas and then they eject you from the bar.
Especially when you start asking the ladies to contribute their underwear to a Mexican Bra Dance. It’s like a hat dance, only better scenery.
You’re a rogue. I like that.
Good, because that mariachi music was driving me bughouse.
As enjoyable as that is, it is even better—and the music even sounds better too—after using YouTube Downloader to save & convert it to Windows Media format, then playing it full screen at “Slow” speed.
Much less frenetic, and easier to see details.
The mariachi music?
What ever the background "music" in the video was, it sounded much better slower...almost like real music.
BTW, did you watch the Spaceweather/NASA ISS video of a couple nights ago? Crossing the US at night, with the aurora visible along the northern horizon?
That was also better saved, converted to WMV, then played full screen/200%/slow. You could see the details, and have time to see what you were watching. I really dislike Quicktime, unless I'm trying to advance & save single frames.
