Solar storms lighting up the skies

A second sunburst this week will affect earth. A coronal mass ejection left the sun on January 19 arrived at earth on January 22. It was a M3 class flare. The Spaceweather.com explanation of the diferent levels of flares, "X-class flares are big; they are major events that can trigger planet-wide radio blackouts and long-lasting radiation storms. M-class flares are medium-sized; they can cause brief radio blackouts that affect Earth's polar regions. Minor radiation storms sometimes follow an M-class flare. Compared to X- and M-class events, C-class flares are small with few noticeable consequences here on Earth." Each category ranges from 1-9. So an M3 is medium sized but on the lower end of the intensity scale.

"The coronal mass ejection (CME) hit Earth's magnetic field on Jan. 22nd. According to analysts at the Goddard Space Weather Lab, the impact strongly compressed Earth's magnetic field and briefly exposed satellites in geosynchronous orbit to solar wind plasma. Shifting lines of magnetic force induced strong ground currents in Norway and sparked bright auroras over the upper reaches of North America." (source)

It isn't an angel but it reminds me of one! How pretty!

An M3 is a good size but an even bigger ejection occurred a few days later. A M9, on the threshold of the largest kind of flare, was ejected. "This morning, Jan. 23rd around 0359 UT, big sunspot 1402 erupted, producing a long-duration M9-class solar flare. The explosion's M9-ranking puts it on the threshold of being an X-flare, the most powerful kind. NASA's Solar Dynamics Observatory captured the flare's extreme ultraviolet flash:"


Discovery.com put it like this:
"You may not know it, but there's an epic magnetic battle between the sun and Earth raging over our heads. On Friday, the sun hurled a coronal mass ejection (CME) at our planet that sparked a strong geomagnetic storm and beautiful aurorae at high latitudes on Sunday. Late last night (EST), the sun unleashed yet another CME... and it's heading our way. A particularly angry-looking sunspot (1402) on the solar surface erupted with a strong, long-duration M9-class flare Sunday night at around 11 p.m. EST. "M" stands for "medium," but the explosive energy was just shy of an X-class solar flare -- the strongest kind of flare the sun can produce. Now that yet another CME is approaching, even more spectacular auroral activity can be expected for the next few nights. We are currently undergoing the largest solar radiation storm since 2005."

It is such a big storm, that NASA advised rerouting jets. "As a rare precaution, polar flights on Earth are expected to be re-routed, Kathy Sullivan, deputy administrator of NOAA, said today at a Meteorological Society meeting in New Orleans, La., according to Space.com."

The sun is getting active. As it does, keep looking up. "There will be signs in the sun, moon and stars. On the earth, nations will be in anguish and perplexity at the roaring and tossing of the sea." (Luke 21:25.)

"Now learn this lesson from the fig tree: As soon as its twigs get tender and its leaves come out, you know that summer is near. Even so, when you see these things happening, you know that it is near, right at the door. I tell you the truth, this generation will certainly not pass away until all these things have happened. Heaven and earth will pass away, but my words will never pass away." (Mark 13:28-31)

Northern Lights come south for a visit

After completing the lowest minimum, the sun is entering one of the most active maximums in recent times. A burst on Monday hit the earth with a powerful blast and the resulting display was tremendous! The Auroras were seen all the way down to Texas and Alabama.

"A coronal mass ejection hit Earth's magnetic field on Monday, October 24 at approximately 2pm ET. This enabled the northern lights to be seen as far south as Arkansas, Tennessee, northern Alabama, northern Mississippi and North Carolina. For most, the aurora appeared as a red glow in the northern sky."

Aren't they gorgeous!? From spaceweather.com--

"Auroras were seen or photographed in more than half of all US states including Alabama, Wisconsin, New Mexico, Tennessee, Missouri, Illinois, Nebraska, Kentucky, North Carolina, Indiana, Oklahoma, Kansas, Iowa, Maryland, New York, Montana, Ohio, Colorado, Pennsylvania, Washington, Minnesota, Maine, Michigan, Oregon, Arkansas and California. Many observers, especially in the deep south, commented on the pure red color of the lights they saw. These rare all-red auroras sometimes appear during intense geomagnetic storms. They occur some 300 to 500 km above Earth's surface and are not yet fully understood."

"People in the United States are still talking about the spooky red auroras ignited by a CME on Oct. 24th; Northern Lights were sighted as far south as Texas, Louisiana, Arkansas and Alabama. 48 hours later, the show was over in the USA, but not in Scandinaviia where residual auroras continued to flicker around the Arctic Circle. Norwegian photographer Ole C. Salomonsen took this picture on Oct. 26th:"


Wow, I love auroras. When God set His rainbow in the sky as a covenant, it is sort of like He is painting. (Genesis 9:13). And with the colorful northern lights, it is like He is painting, also.
