Mark, Was it the June issue of S&T? Just read in Fed Schaff's column about the cycle you refer to. HE referring to the shift tin declination of Eltanin (Gamma Draconis) first noted by James Bradley in the 1720's. Page 50 of the June 05 issue. Interesting.

The current extreme north and south movements of the Moon are part of a cycle that repeats every 18.6 years. Last month the 1st quarter Moon was almost straight up. I think it lasts just the 2 months. It'll be late 2023 before we see the Moon so far from the ecliptic again. It's cool to understand the sky!
