NASA Scientists Blame Dearth of Sunspots on Sluggish Jet Stream

According to a report on the Science@NASA website, researchers think they have discovered the reason behind the dearth of sunspots. At an American Astronomical Society press conference yesterday in Boulder, Colorado, the researchers announced that a jet stream deep inside the sun is migrating slower than usual through the star’s interior, giving rise to the current lack of sunspots.

The good news is that according to their measurements, the jet stream is now finally reaching the critical latitude of 22 degrees, meaning that conditions should return to normal. In other words, no Maunder Minimum, or prolonged period of low sunspot activity, this time around.

Another reason this is good news is that while all this blathering has made for good blog fodder, I’m getting tired of all the complaining. To paraphrase Mark Twain, “Hams like to complain about the solar weather, but nobody does anything about it”!


  1. Yeah, that’s why I am going to withhold my ARRL membership dues…they have not done a single thing about the solar weather.

    There is weather on the sun? Are those dark spots really rain clouds?
