Hi Frank,

Their original anomalous Solar Flux forecast came without explanation and now 
their revision comes many months later without explanation too.

Here is a chart of their original forecast of Sunspot Number Progression (tks 
K9LA)

https://www.swpc.noaa.gov/products/solar-cycle-progression

Apparently they have not updated this yet.

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

Cycle 25 forecast

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).
