Current Solar Cycle The Third Quietest In More Than 250 Years Of Observation

by F. Bosse & Prof. F. Vahrenholt, December 27, 2018 in ClimateChangeDispatch

The sun was much less active in November than normal, comparing all solar cycles 1-23 up to month no. 120 since the beginning of the systematic survey in 1755, the first year of solar cycle 1.

The latest observed SSN (sunspot number) was a meager 5.9 for the monthly average.

On 16 days the sun was completely “spotless.” The maximum number over the days of November was 15, which does not mean that there were 15 spots – no, the number indicates that 5 spots were observed in a maximum of 1 spot group.

So there was very low spot activity, only 20% of the average value.
