Solar Dynamo Still Anemic, Magnetism and UV Lax 156

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.'"

      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.

      • Or maybe Mz. Sun is expecting.

        sunspots would predict that.
        are sunspots a good predictor?
        dunno, but it beats chicken little, at least in terms of track record.

    • Peak solar!

      • by thijsh ( 910751 )
        Yeah, that's what we get for putting up so many solar panels in recent years, notice how this coincides with the graphs... How can we keep tapping the suns energy without thinking about mother earth and father sun... We are doomed! Donate now, and we *might* be able to prevent it (and take full credit for it), but if we can't it's your fault for not donating enough!!! Act now because peak solar is a proven fact, we have some scientists saying something to back it up!

    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.

      The cycles are asymmetric, with stronger cycles being more asymmetric. A slow rise suggests a not so asymmetric cycle which will therefore be weaker.

    When comparing the actual results to the predictions, the brief analysis given by the lead investigator Dr. Sunny M. Sparks was:

    "The fuck?!"

    "Not my fault! I swear! ... It was Jackson! He was playing WoW in the lab computer not two days ago."

    It took me a while to figure out what "solar cycle" meant. I thought it was talking about the 24th day of December. Then with all that talk of predictions of where we are in respect to the day, I had no idea what was going on.

    The Sun is a very old thing. Like most old ham radio operators, SOL didn't like the FCC screwing around with the testing. "BY GUMMIT! I had'ta take the 25WPM test to get my Extra, so should all you youngins!" he was heard exclaiming after the rule change. So ol' Sol got together one morning over coffee with all his buddies on 80 meters and hatched a plan: "I'll just turn down the sunspots for a while, they tend to inflame my gout anyway. That way they'll have to use CW, since they all live in deed-restricted tract houses and can't put up boomers like we have!"

    And so, as the newly-licensed HAMs bought their Miracle Whips and Outbackers, in the hopes of cycle 23 kicking up and making it easy to work the world, their hopes (and bank accounts) were quickly dashed on the reality of all quiet bands (except for those old guys talking about their aches and pains) and those weird sounds at the bottom of the band. Some took to new methods, and some picked up the old ways, but the old guys, with their antenna farms and "full limit" linear amps got to keep "their" voice subbands and coffee klatches, comforted in the knowledge that their frequency will continue to belong to them, for as long as they can keep it.

    • That's the problem, the CW test isn't really as relevant but there *should* be a section on using digital modes like PSK. Then we wouldn't have twats like this []
