   Explanation: This week the equinox found the Sun near the middle, but
   not at the crossing point, of an analemma in its annual trek through
   planet Earth's skies. In this scenic view, that graceful,
   figure-8-shaped curve was intentionally posed above the iconic Danube
   River and the capital city of Hungary. Looking south from Budapest's
   Margaret Bridge it combines digital frames taken at exactly the same
   time of day (11:44 CET) on dates between 2018 September 24 and 2019
   September 15. That puts the metropolitan Pest on the left, regal Buda
   on the right, and the positions of the Sun on the solstice dates at the
   top and bottom of the analemma curve. December's near solstice Sun is
   just hidden behind a dramatic cloud bank.
