Sunspot Activity Continues To Drop

slreboy writes "The sunspot cycle is behaving a little like the stock market. Just when you think it has hit bottom, it goes even lower. The year 2008 was a bear. There were no sunspots observed on 266 of the year's 366 days (73 percent). To find a year with more blank suns, you have to go all the way back to 1913, which had 311 spotless days. Prompted by these numbers, some observers suggested that the solar cycle had hit bottom in 2008. Maybe not. Sunspot counts for 2009 have dropped even lower. As of March 31st, there were no sunspots on 78 of the year's 90 days (87 percent)..."

    The Zeroth Law of Thermodynamics states that bodies in a system must remain in equilibrium. So if we're experiencing global warming where are we getting that energy from? It must be coming from somewhere?

    The answer, fellow scientists, is that we are stealing that energy from the Sun.

    Yes, my charts and ramblings reveal that our greenhouse gases are trapping sunlight ... sunlight that would return to the Sun and heat it back up causing sunspots. I am currently drafting a bill that will move sunspots to the endangered phenomena list. That same bill will introduce that list and hopefully this will be reason enough to form it unlike Senator Kerry's attempt to create the list when he saw Rosie O'Donnell exercising (or so he thought).

    Gentlemen, we must act now. There is no more time for debating and arguing. The sunspots are going away and without that, we may lose our natural magnetic storms and maybe even the precious Aurora Borealis. Our Northern Lights are in danger while you sit back here comfortably in your chairs. Today we are polluters in the hands of an angry environment tomorrow we may be dead. We have angered the environment and now we must face the wrath of the environment. Including, but not limited to, the loss of sunspots.

    I don't know about you but when I was a kid, we celebrated sunspots with our parents. Upwards we gazed directly into the sun, fueling the optometry industry. Yes, sunspots create jobs and foster growth. Do you want to share sunspot gazing with your children and their children? I know I do.

    But all is not lost. The environment is injured and may be weak enough for us to stop it before it kills us all. I propose a preemptive strike now while we still have time. We could sneak in special units disguised in ponchos and Birkenstock's with thermonuclear weapons that would devastate the environment and save us from certain death at its hands. China has already rendered the environment obsolete and it is our turn to follow suit. Gentlemen, the question today is not if we should deal a final blow to the environment but when.

      Actually, no. If at any point in recorded history, you proposed that the earth was flat, the overwhelming majority of people thought you were a nutjob.
      The idea that Columbus' opponents thought the earth was flat was made up by supporters' of Darwin in the 1800's to belittle their opposition (not all of which was religious).
      Columbus' opposition said that if the diameter of the earth was what they calculated it to be (which it turns out was a reasonable approximation of the actual diameter of the earth), Columbus and his crewmen would run out of fresh water before they reached East Asia. Columbus, using his own calculations, said the earth isn't that big. It turns out that Columbus got lucky, because neither side was aware that there was another land mass between Europe and Asia (there is reason to believe that there were Europeans who did know, but that is speculation).

    I realize that HAM radio is a bit of an anachronism in the eyes of most slashdot readers, but it's still the most viable medium for emergency communications. Unfortunately, with sunspot activity being so low, HF communications become very limited. Whole bands of RF spectrum are almost unusable, because the E-layer of the ionosphere can no longer bounce higher frequencies of radio waves. 40m wavelength and lower tend to still be usable, 20m is come-and-go, and 17m and higher become sporadic or completely unusable.

    I'm 31, I've been a HAM for 6 years. My cell phone often doesn't get coverage where I roam, and my power and internet and landline phone have been knocked out by storms and provider mistakes. Radio works when all else fails... ...but sometimes it works better than others!

    Comparing a 90 day period to a 365 day period isn't a like for like comparison (obviously). Statistically it's meaningless.

    Not so. We have two statistical samplings, one with n=90, one with n=365. Based on the sample sizes and some other info, we can establish a confidence interval. Yes, the interval will be larger for the 90-day sample... but just because we can't be 100% confident of the exact results doesn't mean it's statistically meaningless.

    One other note -- historical data must be used to establish that there are not periodic cycles with a frequency of less than one year, which would make the 90-day sample set inaccurate.
