The June 2020 data shows that the smoothed sunspot number for December 2019 decreased a little bit again. It’s obvious now that this current minimum period will be longer than the last minimum period. It can’t go down much more (!!), so the question is “when will it start going up?”

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 (December 2019).

June 2020 was a good month for Cycle 25 sunspots.
