That sounds like Gnevishev, M. N.; Ohl, A. I. (1948). "On the 22-year cycle of solar activity" which first appeared in the Russian journal Astronomicheskii Zhurnal 76 years past.
Very interesting! but not that - it was much more recent, few years ago. What I'm thinking of was not writing about a 22 year cycle; it was arguing for two independent cycles, one deep in the solar atmosphere, one toward the surface.
Sure, you more than likely did read a more recent paper.
That said, the earlier paper was about two cycles, the already known 11 year cycle and seperate observations that only occurred every two 11 year cycles.
There's a chance the two papers are related via a common coupled driver, or not.
