The Space Weather Prediction Forecast of Solar Activity has been posted for 2021. You can see that we are starting into another Solar cycle of sunspot activity.
SOLAR CYCLE 25
The international SC25 prediction panel expects a maximum smoothed monthly ISN for SC25 of 115 +/-10 (see this Newsitem at Two sunspot groups from the new solar cycle | STCE ). The evolution of SC25 can be followed on dedicated solar cycle webpages at NOAA/SWPC (Solar Cycle Progression | NOAA / NWS Space Weather Prediction Center ) and at SILSO (Sunspot Number graphics | SILSO ) - see the charts underneath. By the summer of 2022, the factual observed sunspot numbers will give a better estimate of the SC25 maximum that can be expected.
