From WIA News 22nd January 2021 :
Will Solar Cycle 25 Dazzle or Fizzle in 2021?
Tad Cook, K7RA in an ARRL post to all radio amateurs asks "What happened? Solar Cycle 25 seemed well underway, but no new sunspots emerged since last year prior to Christmas, on December 23, 2020 to be exact. The last time any sunspot was visible was on January 2."
On January 14, the day prior to Tads post, Spaceweather.com posted, "Welcome back, solar minimum."
Average daily solar flux declined from 78.6 to 73.8. Geomagnetic A index remained quiet
BTW (But Then Wait)
A new study being reported on in universtoday.com suggests that Solar Cycle 25 may be more powerful than previously predicted.
It's the big question in wireless weather for 2021 and the new decade. Will Solar Cycle 25 wow observers, or be a washout? This new study goes against the consensus, suggesting wemay be in for a wild ride if predictions and analysis of past solar cycle transitions hold true.
The last Solar Cycle 24 was a historic under-performer, starting from early 2011 (based on the termination of Cycle 23). This lacklustre cycle produced a sunspot number of just 116, and featured year 2019 with over 281 spotLESS days (thats 77% of the year) for the Earthward face of the Sun, the longest dearth of sunspots in over century.

So, is propagation going to improve over the next 4-5-6 years or is Solar Cycle 25 going to be a proverbial 'dead dog' ??
