Hi Frank, 

Thank you for posting that. If I recall correctly, this is a DRAMATIC revision in forecast compared to what the NOAA had on their website in March 2019 (Solar Flux plunging to the upper 50’s and remaining there for several years) that you and I discussed and I challenged the accuracy of. 

https://www.swpc.noaa.gov/products/predicted-sunspot-number-and-radio-flux 

Have you seen any explanation for their revision? I can’t find one. 

Tnx & 73

The forecast consensus: Cycle 25 will peak in July 2025 (+/- 8 months), 
with a smoothed sunspot number of 115. 
Cycle 25 is forecast to be average in intensity and similar to Cycle 24. 
The panel concurred that solar minimum will occur in April 2020 (+/- 6 months). 
If their solar minimum prediction is correct, this would make Cycle 24 
the 7 th longest on record (11.4 years). www.swpc.noaa.gov/news/solar-cycle-25-forecast-update
