Eli's opinion on these things has always been wait.

Sad days at WTF, although the more dedicated there will bravely carry on with curve-fitting. After all, the moment after each surge of solar activity could be the start of the mother of all grand minima. Who among them can say otherwise?
my guess would be that the surface intensity distribution of an active Sun is irregular, and that of an inactive Sun, smooth. The fluctuation you see is due to the 30-odd day rotation period of the Sun, turning at random combinations of light and dark patches of Solar surface towards Earth. The downward spikes are large sunspot groups.
I enjoyed the clip. The music is from the movie Sunshine, which I enjoyed even if no-one else did. I also like that you can see the particle tracks in the CCD during the eruptions in the corona images.
Eli Rabett is a not quite failed professorial techno-bunny, a chair election from retirement, at a wanna be research university that has a lot to be proud of but has swallowed the Kool-Aid. The students are naive but great and the administrators vary day-to-day between homicidal and delusional. His colleagues are smart, but they have a curious inability to see the holes that they dig for themselves. Prof. Rabett is thankful that they occasionally heed his pointing out the implications of the various enthusiasms that rattle around the department and school. Ms. Rabett is thankful that Prof. Rabett occasionally heeds her pointing out that he is nuts.

Why is there such a dramatic decrease in fluctuation from (using my Eyeball Mark I) Jan 2008 to Jan 2010?
