Northbound Echosun

The noon Sun stands where it will stand again months later, heading north now.

At clock noon the Sun is in the same spot it will occupy on Aug 30, but now it is moving north.

The name

Echosun: one of the two days a year when the noon Sun returns to a spot it held months before, or will hold months later, where the analemma crosses itself. Northbound and Southbound give the direction.

Precision

Found where the curve crosses itself. Good to about a day.

Every year

Between 1900 and 2100 it comes as early as April 11 at 16:44 UTC (2096) and as late as April 14 at 08:24 UTC (1903).Dates wobble through each four-year leap cycle and creep earlier across a century, until a skipped leap day, as in 1900 and 2100, sets them back.
