Some recent solar articles are freaking out, proclaiming that the Sun is waiting to unleash it’s fury on the Earth (re: Warning: Sunspot cycle beginning to rise) or that it’s lowering its energy output, possibly kickstarting Maunder Minimum 2.0 (re: New Forecast Calls for Calmer Sun).
So which one is it? Is the Sun just biding its time, waiting for the perfect moment to fire a salvo of flares at us? Or will it remain quiet, well into Solar Cycle 24, impacting our planet like the Maunder Minimum did during the Little Ice Age from the 16th-19th century?
It’s funny actually, both the above articles are based on the same research, and yet two very different conclusions were drawn from the text.
On the one hand, the Sun is acting rather strange; it’s undergoing a sustained solar minimum, the longest period of low sunspot population for the best part of a century. On the other hand, when the Sun does get active, steadily growing to a peak in activity for the 2012-2013 predicted solar maximum, the resulting flares and coronal mass ejections (CMEs) could inflict $2 trillion in damages on global infrastructure (according to a recent study), leaving us to mop up the mess for a decade. It’s these two extremes that are causing such a stir, generating the attention-grabbing headlines.
However, I seriously doubt that we are facing another Little Ice Age and I am highly skeptical of the predictions that the 11 years of Cycle 24 are going to be overly violent. To be honest, we just don’t know. Considering we live so close to the Sun, we actually know very little about it; to even begin trying to predict what it’s going to do next remains problematic.
That said, once the Sun starts producing lost of sunspots, this means magnetic activity is on the rise and solar activity is increasing, so when I see sunspots rotate into view, I can’t help but be a little excited. Today, it happened, two active regions appeared on the disk of the Sun. Could this be the real start to the solar cycle?
Today’s image is a magnetic map of the sun. Two active regions are circled. Their polarity identifies them as members of new Solar Cycle 24, but they lack the dark cores required of true sunspots. So, in spite of these lively magnetic imprints, we must still say “the sun is blank–no sunspots.” —SpaceWeather.com
No sunspots, another blank disk day and therefore low magnetic activity still.
How dull.
