Solar Dynamo Still Anemic, Magnetism and UV Lax

radioweather writes "While we are well along into solar cycle 24, there remains a significant gap between the predictions of where we should be, and where we actually are in the progression of the cycle. Recently, the sun went spotless again, and the solar Ap geomagnetic index, an indicator of the solar magneto, hit zero. It is something you really don't expect to see this far along into the cycle. In other solar news, scientists monitoring the SORCE solar satellite have found that solar ultraviolet emissions have dropped significantly in the past few years. The Solar Irradiance Monitor on the satellite 'suggests that ultraviolet irradiance fell far more than expected between 2004 and 2007 — by ten times as much as the total irradiance did — while irradiance in certain visible and infrared wavelengths surprisingly increased, even as solar activity wound down overall.'"

Sharp rise?

Is it just me, or dose it seem the curve for the prediction coming out, shows a faster return then the fall coming in?

A longer lower end may be followed by a slow return too.

Could be. We know Mr. Sun can take long naps. And the one time we know for sure it happened was also known as the Little Ice Age.

Don't go placing bets yet but hedging against it might be a prudent thing.
