MORE ON THOSE MISSING SUNSPOTS: “The Sun has been strangely unblemished this year. On more than 200 days so far this year, no sunspots were spotted. That makes the Sun blanker this year than in any year since 1954, when it was spotless for 241 days. The Sun goes through a regular 11-year cycle, and it is now emerging from the quietest part of the cycle, or solar minimum. But even for this phase it has been unusually quiet, with little roiling of the magnetic fields that induce sunspots.”
