  1. A solar cycle lasts about 11 years. At the end of a solar cycle, the north and south poles change places. During a cycle, the same fluctuation of solar radiation, solar flares and sunspots always takes place. Until about the middle of the solar cycle the activity of the Sun increases, the number of sunspots increases, the eruptions of the Sun are intense and frequent, then everything becomes quieter again, the transition from one solar cycle to the next is a phase of low solar activity, characterized by the (extensive) absence of sunspots. The year 2019 has gone down in the history of sunspot counting as one of the years that had the longest phase of consecutive days when NO sunspot was seen. For 281 days in a row (77% of the days) the Sun remained without spots. Since the counting of sunspots, only the year 1913 has seen more days without sunspots. The transition from solar cycle 24 to the new solar cycle 25 is special in that it is associated with an extremely long period of calm Sun. Scientists agree that solar cycle 25 will be weaker than solar cycle 24, i.e. fewer sunspots, fewer solar storms, a weaker magnetic field of the Sun, etc. How much weaker it will be is debatable. However, the long continuous phase without sunspots gives rise to fears.
  2. Regardless of the solar flux, it is - for historical reasons - always correct to roughly schedule the beginning of SC 25 for December 2019. The archives give this as a reasonable date. In this respect I can agree with Patrick's statements without exception.
  3. Could the M1 flare of 29.5. not have been an indication of increasing solar activity? It is consensus that the solar activity will increase during SC 25. The only question is when. Could the increase in solar activity perhaps occur in a shorter time than generally predicted? After all, the solar radiation remained in the B range for several days. Please bear with the poor English of a pensioner.
