The STEREO-Behind 195-A images show two active regions in the northern hemisphere that are close together and have started electromagnetically interacting with each other. These are pretty much prime conditions for x-ray flares and CME's IMO.

If you've got bandwidth to burn, these two SDO images are very cool and show the active areas coming over the horizon at about the 10:00 position.

The second image shows the effect of the coronal loops coming up and through the photosphere and the effect of these discharges on the surface (and above the surface) of the photosphere.
 
Hey, that LASCO-C3 SOHO image is a "two-fer". If you look closely at about the four oclock position, you can watch an incoming meteor start to burn up in the solar atmosphere around the same time as the CME occurs.

The link above is typically about 40 megs so be prepared. :)

IMO the 1600A wavelength from SDO is great for showing the effect of the discharges on the surface (and above the surface) of the photosphere. If you watch around the 10:00 position, you can see the effect of the CME on the surface of the photosphere about 4:52 this morning. You can also watch the coronal loops come up and through the photosphere and light up the surface of the photosphere in the process.
 
STEREO (Behind) captured that last CME pretty much "face on", where as SDO shows it from a side angle in much higher resolution:

SDO 193A (side angle at about 10:00).

Interestingly enough, even the 1700A SDO images show the same "line" of activity on the surface of the photosphere during the CME as can be (better) observed in the 1600A images.

I still have Mozina in ignore, but I have no doubt that this thread is just more

Two types of CME's.

http://sdo.gsfc.nasa.gov/assets/img/dailymov/2010/09/22/20100922_1024_0193.mpg

There seem to be at least two types of CME's that took place on the 22nd, one that I would describe as an electromagnetic CME, and one I'll describe as a "dark CME" (cause I know you guys love dark stuff, and this does begin with dark plasma). Both types are visible on the 22nd in the SDO data. The electromagnetic CME took place about the 10:00 position between the two active regions coming over the horizon. That was the CME I expected. The other one however takes place in the northern polar region and seems to be related to "dense" or "dark" plasma that rises up from the photosphere and eventually "blows" for lack of a better term. That one I did not expect but there are "signs" associated with these types of CME's just as there are 'signs" that of an electromagnetic flare/CME.

The electromagnetic surface interactions triggered the first flare along the limb, but the northern flare almost looks "chemical" in terms of the source of the explosive force, and there is an "evaporation" sort of process that takes place during that type of a CME. I noticed that type of CME in the SOHO data a few years ago. These seem to be "polar" processes for the most part and typically form in the northern hemisphere.

The SOHO image actually accentuates the "dark' flare/CME scenario better than the SDO image IMO. I probably should have saved the 48 hour SDO loop video at 193A that showed the process a little more clearly because of the longer duration.

The effect of these electrical discharges on the surface of the photosphere is most visible in 1600A SDO images. The flare process clearly begins *UNDER* (not above) the photosphere and the mass flow through the photosphere light up the surface in 1600A. The same effects can be seen in the 1700A images as well, but they are most visible in the 1600A images/videos.
 
Bandwidth to burn....

If you have a lot of bandwidth to burn, IMO the 94A images give the clearest view of the (now) three "active" areas that are interacting with each other. The newest of the three (furthest right active area) is currently the most active of the three regions, but the center active region has been discharging intensely as well. The far right active area is the most unstable of the three, and has the most potential for further activity, but the center active region is also highly unstable, and all three of them can produce CME's and flares. We may see another flare from this region before it rotates over the horizon.

If you've got bandwidth to burn, the 94A SDO images have a very interesting feature in them today. You can watch the active region on the right at about the 2:30 position "glow discharge" to an area in the north. It looks virtually identical to the ray like discharges that my "small" plasma ball makes when you touch the sides. The discharge is unusual in size, and very interesting IMO.

No really spam - more of a case of Michael Mozina talking to himself.
For some reason he thinks that his musings about "predictions" of activity from active regions means something. He does not seem to realize it is about the same as saying that there will be high rainfall during winter!

Solar activity is interesting in itself. But there are plenty of resources out there other than MM's little thread.

Um, how exactly in your mind is "There will be a dark filament induced CME in a few hours from a specific area of the sun" the same as "it's going to rain in the winter"?

FYI, this is the first dark filament induced CME I've seen in the southern hemisphere. Usually the filamentary discharges occur in the northern hemisphere.
