This is the full frost moon rising over Lake Tahoe on 14 November of 1997.  This year, 2016, the moon will be full again come the 14th, and travel the night sky once again with its companion stars in Taurus.  Vision and revision.
This 19 year interval is called the 'Metonic Cycle' after the Greek astronomer Meton who observed that 19 years is common multiple of the solar year and the lunar month — 19 years is almost exactly equal to 235 synodic months and, rounded to full days, counts 6,940 days. The difference between the two periods (of 19 years and 235 synodic months) is only a few hours, depending on the definition of the year… and by the calculations we use here at Indigo, this particular interval is off by just 19 minutes.  That is to say the difference between the exact moment the moon was full in November of 1997 and November of 2016 is 19 years less 19 minutes.
I've always liked that number: 19.
Both moons travel the November sky in Taurus, at the same point on the ecliptic, balanced between the Hyades and Pleiades, close to a minor player, Lambda Tauri, a faint star, actually an eclipsing binary.
I especially like the fact that this has nothing to do with making America great again.
