The sun was also very sub-normally active in February. Although we are in the middle of the minimum, the sunspot number of 0.8 for the 123rd month into the cycle is very low. On 26 days of the month no spots were visible, only on 2 days was there a little, symmetrically distributed over both solar hemispheres.The only exciting question currently: When will the minimum be finished and will solar cycle 25 begin? Although 6 spots of the new cycle were already visible in February with a significantly higher resolution, estimates are difficult.March again was dominated by some spots of the “old” SC24.  The rule: “weaker cycles often last longer than stronger cycles” could hold.

Figure 2: The strength of the sunspot activity of each cycle in comparison. The numbers in the diagram are obtained by adding up the monthly deviations between the observed values and the mean value (blue in Fig.1) up to the current 123rd cycle month.

Figure 2 shows that five cycles (No. 8, 15, 16, 18, 22) did not have a month 123 at all. Instead the following cycle started. In this respect, the picture is now somewhat distorted towards the end of the cycle.
