Sun Spot Activity

While it hasn't been widely reported it seems the sun is slower than normal to kick off its new solar cycle. Sunspot activity has been off from projections. You can check out a near real time picture of the sun here:

Seems that with each passing month, they reduce the projection for sunspot activity over the next cycle:

Perhaps another "Maunder Minimum" in the works?

Sun Spot Activity

I've brought up the lack of sunspot activity in a couple of past threads. Sunspot activity started dropping off over a year ago, and I believe it was last August or September that was totally sunspotless for the whole month. Something that had not occurred in over a century.

Some more links that may be of interest, with a bit more info on sunspots.

If this continues, we're headed for an ice age! Ugh...

Oh, great...I knew that if we didn't get all this CO2 under control, we'd clog up the sun.

Sun Spot Activity

Sunspots are planet sized areas on the sun's surface that are cooler than the surrounding surface. Why the areas are cooler has to do with magnetism and probably a good deal of fluid dynamics.

The net result is that the sunspots directly correlate with the energy radiation of the sun. More sunspots, more flares, and the amount of energy striking the earth increases.

The number of sunspots have a roughly 11 year cycle. Solar maximum has the most sunspots, solar minimum (which we are in now) has the fewest or no sunspots.

Sunspots have been actively counted for some time and the scientific record dates back to the early 1600's.
