Sunspot update: Sunspots in January went through the roof!
NOAA this week updated its monthly graph that tracks the number of sunspots on the Sun’s Earth-facing hemisphere. Below is that updated graph, with January’s numbers added to the timeline. As I have done monthly for the past dozen years here on Behind the Black, I have added some additional details to that graph to provide context.
Just as in December, the number of sunspots in January 2023 shot up to the highest amount since September 2014, which was during the previous solar maximum. Unlike December, however, January’s numbers came only a hairs-breath from topping that 2014 number. In fact, except for that one 2014 month, January 2023 saw the most sunspots on the Sun since November 2002, twenty years ago. In 2002 the Sun was ramping down from what had been a relatively strong double-peaked solar maximum, and was about to begin an extremely long period of little or no activity, followed by a very weak double-peaked solar maximum in 2013.
That period of little activity also corresponded with a long twenty-year period in which the Earth’s climate appeared to stop warming.
