Explanation:
The Sun's annual
waltz through
planet
Earth's
sky forms a graceful curve known as an analemma.
The
analemma's figure 8 shape is tipped vertically at far right in this
well-composed
fisheye view from Budapest, Hungary.
Captured at a chosen spot on the western bank of the Danube river,
the Sun's position was recorded at 11:44 Central European Time
on individual exposures over days spanning 2015 July 23 to 2016 July 4.
Of course,
on the northern summer solstice the Sun is at the top
of the curve, but at the midpoints for the autumn and spring
equinoxes.
With snow on the ground, the photographer's shadow and equipment bag
also appear in the base picture used for the composite panorama,
taken on 2016 January 7.
On that date, just after the winter solstice,
the Sun was leaving the bottom of the beautiful curve over
the blue Danube.
