The July 2020 monthly mean data results in a smoothed sunspot number for January 2020 (the red curve) that moved up a bit. July was a good month for Cycle 25 sunspots, and if it keeps up the smoothed sunspot number will keep increasing. For the record, NOAA/NASA predicts that solar minimum will be between October 2019 and October 2020 (April 2020 +/- 6 months). This prediction is very reasonable based on the latest smoothed data shown above (January 2020). |

July 2020 was as good a month for Cycle 25 sunspots as was last month. Let’s hope they keep coming! |
