Sunspot update: An active October heralds the likely end of solar minimum
With the start of a new month it is once again time to publish another sunspot update. NOAA yesterday updated its monthly graph for tracking the Sun’s monthly sunspot activity. As I have done now every month since this website started in 2011, it is posted below, with additional annotations by me to show the past solar cycle predictions.
Unlike September, which saw almost no sunspots, October was a very active month, with the amount of sunspots far exceeding prediction. Furthermore, every sunspot during the month had a polarity assigning it to the new solar cycle, not the last.
