   Explanation: This week the equinox [5]found the Sun near the middle,
   but not at the crossing point, of an analemma in its [6]annual trek
   through planet Earth's skies. [7]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 [8]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. [9]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.
