Sol Grooves to it's own Beat

Well my friends, our beautiful star Sol is once again dancing and grooving to the beat of it's own drum.  Over the course of the past two months, the sun has sorta picked up the pace from what has been a very very quiet solar maxim.  This past two weeks has been an exciting one for sure, with multiple solar events, a rather large CME from a filament ripping off the surface, another large full halo CME last week just as sun spot 2192 began it's rotation from the farside to earth facing positioning.

In the past 3 days we have seen one X Class flare on the 19th, followed by 8 M Class flares over the past 48 hours.  The most powerful one happened last night just before 2am UTC.  All the major and minor flares (multiple C Class flares over the past 3 days as well) have  been brought to us through sun spot 2192, which has developed into a massive spot and is still gathering size, with a complex Beta Gamma Delta configuration.

One of the things that I'm finding intriguing this morning is that the M8.7 flare last night was originally listed as M9 (see the Space weather note below).... and it had all the markings of blasting off a CME- which would be directly Earth facing, yet so far there has been no updates to show a CME.  Interestingly enough, over the past month of flares, there has only been one CME listed in the updates from an M7 flare Oct 2nd, and one CME last week from the far side flare of 2192 on the 14th.

As 2192 is now directly in geomagnetic alignment with Earth, I will be watching with keen interest to see if, like so many other monster sun spots have done over the past two years, it will suddenly go quiet now that it's directly Earth facing.   I will also note that we have a good size Coronal Hole directly Earth facing on the leading edge of spot 2192, and a new sunspot is about to rotate into view from the eastern limb- old spots 2181 & 2182 are making another appearance (and will be given a new numerical designation once they are Earth facing)- 2182 let off 3 M Class flares on Oct 9th on it's last jaunt around, and from the look of the few farside pics, 2181 seems to of grown in size..... could be interesting!

Coronal holes on October 22nd 2014

In other solar based news, we will see- or at least, everyone in North America will see- a partial solar eclipse today, starting around 2pm PDT.

What's up in space
On October 23rd there will be a partial eclipse of the Sun. Got clouds? No problem. The event will be broadcast live on the web by the Coca-Cola Science Center.
Solar Eclipse Live
PARTIAL SOLAR ECLIPSE: On Thursday, Oct. 23rd, the Moon will pass in front of the sun, off center, producing a partial solar eclipse visible from almost all of North America. The action begins at approximatey 2 pm PDT. Get the full story from Science@NASA.
LOTS OF SOLAR FLARES: During the past 48 hours, monster sunspot AR2192 has unleashed seven M-class solar flares. The most powerful of the bunch (Oct 22nd at 0159 UT) was an M9-class eruption that almost crossed the threshold into X-territory. NASA's Solar Dynamics Observatory recorded the extreme ultraviolet flash:
UV radiation from the flare ionized Earth's upper atmosphere, causing a brief blackout of HF radio communications on the dayside of Earth (e.g., parts of Asia and Australia). In addition, the explosion might have hurled a CME into space. Confirmation awaits the arrival of coronagraph data from the Solar and Heliospheric Observatory (SOHO). Stay tuned for updates.
More flares are in the offing. AR2192 has an unstable 'beta-gamma-delta' magnetic field that harbors energy for powerful explosions. NOAA forecasters estimate at 65% chance of M-class flares and a 20% chance of X-flares on Oct. 22nd. Solar flare alerts: text, voice
