    Solar Scientists Agree That the Sun's Recent Behavior Is Odd, but the Explanation Remains Elusive
    The most recent solar minimum was both long and pronounced. But why?

    I've been watching this solar cycle almost daily on spaceweather.com and to me personally its seems pretty normal. Sure it was off to a delayed start but still within the bounds of long-cycle variations. I'm one of those with the opinion that you cant really predict the sun anyway. Our observation of it is way to short-lived for that. Anyhow, March and April was quite active in terms of sunspots if I recall correctly, plus many filaments that produced flares. The past few weeks have been a tad too quiet though...IMO.
