The Silicon Graybeard: Solar Cycle 25 Progression Update – Jan ’23

I’ve been posting solar cycle updates for a very long time – a casual look shows one in 2013 and that one refers to a post six months prior.  I usually try to keep them around six months apart, in attempt to keep them focused on the “big picture” rather than day to day events like minor flares or Coronal Mass Ejections.  The last one was last July, so this is as good a day as any to put one up.

To begin with, I’ll start with today’s version of the same plot last July’s post did, the Cycle 24/25 plot from the National Oceanographic and Atmospheric Administration, NOAA, and their Space Weather Prediction Center.  This plot shows the sunspot numbers and you can read numbers directly by hovering your mouse over one of the points on the chart – on the website linked there, not this graphic.  The smoothed red curve is the predicted values while the jagged points on the purple curve are measured data.

I did a screen capture from the NOAA site showing the smoothed sunspot number for December ’22 of 113.1  The smoothed Solar Flux Index (SFI – the plot directly below this one on that NOAA site) for December was 148.5.  Remember this is an average over the month; I recall days around Christmas when solar flux was in the 160s.  Furthermore, since the start of the year (notice how that sounds more impressive than “for the last two weeks?”), the SFI has been above 160.  It crossed 200 early in the month and is currently 234; today’s sunspot number is 186. These values are well above the NOAA/NASA predictions.
