Watch 3 years of solar activity in a 3-minute video
LATimes ^ | April 24, 2013, 4:27 p.m. | Deborah Netburn

The video above was created by stitching together two of those images per day over a three-year period. The images in the video were taken in the extreme ultraviolet range and represent solar material at temperatures of about 600,000 Kelvin. Each image is displayed for two frames.

That spinning motion you see is the sun's 25-day rotation, and over the course of the video, you should be able to see solar activity grow as the sun nears the pinnacle of its 11-year solar cycle.

At the 00:30 mark and at 2:28 you can spot a partial eclipse of the sun by the moon, at 1:11 you will see the Aug. 9, 2011, X6.9 Flare, which was the largest solar flare of this solar cycle, and at 1:51 you will see the transit of Venus.

The sun does appear to subtly increase and decrease in size over the course of the video, but that's because the distance between the Solar Dynamics Observatory and the sun has changed a bit over time.

With so little solar activity in terms of sunspots it’s chilling things down a bit.

Why So Much Snow This Spring?
http://iceagenow.info/2013/04/snow-spring/

“Snow cover in the previous 10 years on this date hasn’t even come close to reaching this extent”

More than 91 percent of the upper Midwest also has snow on the ground as of today (April 24), meteorologist Jason Samenow wrote at the Washington Post’s Capital Weather Gang blog. “Snow cover in the previous 10 years on this date hasn’t even come close to reaching this extent (ranging from 19 percent to much lower).”

Thank you for posting this vid.

God’s great plan in motion. Humbling and uplifting at the same time.

Let’s see what the weather looks like in about 6 years (closer to the usual solar minimum time). Saw much colder than usual winter and spring weather at high altitude here. ;-)

We had a pretty cold winter here, too, but it was normal. Seemed worse because we didn’t really have a winter last year.

I’m in Colorado on the Rockies. Up your way, winters should be closer to normal during a solar minimum, if what little history I read about those times is accurate enough. But folks in the Midwestern US should see more of what you’re accustomed to. ;-)
