Sunspot Cycle 25 Strongest Ever
A research paper, "Overlapping Magnetic Activity Cycles and the Sunspot Number: Forecasting Sunspot Cycle 25 Amplitude," by Scott W. McIntosh, Deputy Director of the National Centre for Atmospheric Research in Boulder, et al., has concluded that Solar Cycle 25 could be among the strongest sunspot cycles ever observed, and will almost certainly be stronger than the just-ended Solar Cycle 24 (sunspot number of 116).
The scientists say it will also most likely be stronger than Solar Cycle 23 (sunspot number of 180).

From WIA news for 13 Dec 2020....
Edit note :
While Cycle 23 was pretty good from VK4, like working into the UK on 6M SSB a couple of times, something better that the 180 count from then could be very interesting for VHF DX, particularly given the improvements in the equipment used today : bandwidths, modes, transmit power and receiver performance. Contemplating FT8 (or successor) operation in 2025-2026 bears some planning.
Perchance, I went back to see what the count values from 1958 - the IGY - were like, the year(s) that blew all preconceptions about VHF DX-ing away. :
"
Solar cycle 19 was the nineteenth solar cycle since 1755, when extensive recording of solar sunspot activity began. The solar cycle lasted 10.5 years, beginning in April 1954 and ending in October 1964. The International Geophysical Year occurred at the peak of this solar cycle.
The maximum smoothed sunspot number (SIDC formula) observed during the solar cycle was 285.0, in March 1958 (the highest on record[3]), and the starting minimum was 5.1.
During the minimum transit from solar cycle 19 to 20, there were a total of 227 days with no sunspots. This was the lowest number since 1850.
