The Sun’s activities were notably lesser during 2019 and early 2020. The chart below, List of Solar Cycles, lists the past 24 Solar Cycles. Solar activity is expected to ramp up until the predicted solar maximum as early. If solar cycle 25 turns out to be stronger than its predecessor, that weakening trend would end, supporting an idea called the Gleissberg cycle. 5 SSN. I’d like to see that chart extended beyond the bottom (2009) as there could be a delayed feedback loop, but I think there have been. The Solar Cycle 25 prediction of Helal and Galal used the new calibration of R Z and found that the number of spotless days was a better predictor than with the old calibration [as discussed in Pesnell, 2012]. The Solar Cycle 25 Prediction Panel, an international group of experts co-sponsored by NASA and NOAA, predicted that this would be a below-average solar cycle, like the one before it – Solar Cycle 24. The authors predicted using the observed data for solar cycles 21-24 that the solar activity during the upcoming solar cycle 25 will be weaker in comparison to the ongoing solar cycle 24, and also. “They’re an almost perfect match. The forecast consensus: a peak in July 2025 (+/- 8 months), with a smoothed sunspot number (SSN) of 115. This chart shows the original predicted number of sunspots, represented as the blue line. In 2020, the first full year of Solar Cycle 25, there were 9 days with at least minor (G1-class) geomagnetic storms.
