After literally years of inactivity, well below all initial predictions, the Sun truly came to life this past month. Below is the March monthly update of the Sun’s sunspot cycle, published by NOAA’s Space Weather Prediction Center. The red curve is the prediction, while the dotted black line shows the actual activity.
As you can see, the Sun’s sunspot activity shot up precipitously. Though I don’t have the data from past years, the March jump appears to me to probably be one of the fastest monthly rises ever recorded.
Does this mean the newest prediction from the solar scientists at the Marshall Space Flight Center calling for a weak solar maximum in 2013 is wrong? Probably not, though of course in this young field who knows? I would say, however, that the overall trend of the data still suggests the next maximum will be very weak.
Stay tuned! The next few months should finally give us a sense of where the next maximum is heading.
