Is our Sun falling silent?

B.B.C. Article
"I've been a solar physicist for 30 years, and I've never seen anything quite like this," says Richard Harrison, head of space physics at the Rutherford Appleton Laboratory in Oxfordshire.
He shows me recent footage captured by spacecraft that have their sights trained on our star. The Sun is revealed in exquisite detail, but its face is strangely featureless.
"If you want to go back to see when the Sun was this inactive... you've got to go back about 100 years," he says.
This solar lull is baffling scientists, because right now the Sun should be awash with activity.
It has reached its solar maximum, the point in its 11-year cycle where activity is at a peak.
This giant ball of plasma should be peppered with sunspots, exploding with flares and spewing out huge clouds of charged particles into space in the form of coronal mass ejections.
But apart from the odd event, like some recent solar flares, it has been very quiet. And this damp squib of a maximum follows a solar minimum - the period when the Sun's activity troughs - that was longer and lower than scientists expected

It's angry about gay marriage. Holding it's breath.
The problem with fantasies is you can't really insist that everyone else believes in yours, the other problem with fantasies is that most believers of fantasies eventually get around to doing exactly that.

They showed a massive coronal mass ejection and its impact with the magnetosphere on Stargazing Live on the Beeb here last week, along with a particularly energetic grouping of sunspots. Dunno if that means anything...

Yep, I'm not quite sure where this is coming from either, the sunspot cycle is continuing ... with variation ...

I've heard evidence of it on the ham bands....
