I came across this article today:

It presents an interesting aspect of sunspot activity, and an inherent and periodic asymmetry in solar cycles over a period of 8-12 cycles. There is talk among the scientists that study solar cycles, that SC25 has reached its peak, and will decline from here. However, in my own research of historical cycles, there often appears to be a bi-modality to cycle peaks. This was more pronounced with SC24 than in the prior few cycles, but each cycle, notably 23 and 22, less so 21 and 20, exhibit some degree of two peaks, separated by six months to a year. This is more notable in the monthly  smoothed average plot, but can still be evident in the daily averages and absolute count plots. 

Thus far in SC25, it appears most of the activity has been in the southern hemisphere. We hit sunspot counts in August that we haven't seen since SC23, with counts hitting as high as 382 on 8/9/24. These counts are no official yet and based on computer counts and estimates, however even when official counts are published early next week, the expectation is that the counts will be the highest seen since March 2001 at the very least. Despite these high counts, however, if there is hemispheric asymmetry this cycle, it stands to reason that SC25 is far from over. The activity of southern hemisphere may have reached its peak, however we may well be in for another show within 6-12 months as the northern hemispheric activity peaks. 

There are a decent number of astrophotographers here on ABin who regularly capture solar activity. Thought this bi-modality of solar cycles and the potential for more activity in the northern hemisphere might be intriguing, and maybe an avenue for amateur research on the subject.
