Unless someone puts in the time to ask some questions and the like it can get pretty dead here.
I note how small the sunspots are on average, my fav topic as the general conclusion from the size of spots is that the magnetic field per spot is dropping and it might get very quiet on the sun soon. If it does, does that have any meaning for the earth?
I still await the next L & P update from Leif, it has been awhile...
Well, I hope discussion here doesn't follow solar activity in it's probable decline over the next few months!
If I understand the basics, the decline is more likely over the coming cycle than now. That said, as the magenetism per spot drops and the flux and size drop with it we will likely have a different sun even in this cycle. The real question is, does the total solar irradiance change or the type of radiuation emitted - if it does now or into the future there might be big implications for our little planet.
The L+P effect does on the whole seem to be holding, put it would indeed be nice to have some of the latest figures, I agree.
The SSNs for June so far are interesting, in that we may get a peak this month or next, meaning that we've got for this first time this cycle a definite secondary peak ( in March ). These secondary peaks, for want of a better term, were a strong feature of cycle 14. What this all means, though, is another matter. Is this a manifestation of the L+P effect, perhaps? Would the 7 monthly or so peaks chracteristic of this cycle and of cycle 14 be caused by the L+P effect, and if so, how?
If not available, it might be a nice add to your website as the question, if SORCE is calibrated correctly, is what happens over time as we go through this unprecedented period with total solar irradiance and changes in radiation type.
An M2.5 flare peaked at 06:41 UT, June 7, 2011. The active region 1226 is located in the southern hemisphere at the west side of the visible solar disk. The magnetic configuration of the active region did not change however dramatically in magnetograms. Magnetograms show the strength of the line-of-sight surface magnetic field. The flare - a flash of radiation -as associated with a plasma eruption. SDO/AIA 304 shows the impressive plasma eruption. The plasma cloud is already visible in SOHO/LASCO and STEREO A-B/COR images. A first estimate gives a speed over slightly more then 1000 km/s. The cloud seems to have a large extend and might cause geomagnetic disturbances arriving at Earth in 2 days. The proton levels went up immediately. >=10MeV and >=50MeV curve passed the thresshold. This proton event is flare-driven.
