Explanation:
Today, the
solstice
is at 15:54 Universal
Time, the Sun reaching the northernmost
declination in its yearly journey through planet
Earth's sky.
A June solstice marks
the astronomical
beginning of summer in the northern hemisphere and winter
in the south.
It also brings the north's longest day, the
longest period between sunrise and sunset.
In fact the June solstice sun is near the top, at the most northern
point in the analemma or figure 8 curve traced by the
position of the Sun
in this composite photo.
The
analemma was created (video) from images taken every 10 days
at the same time from June 21, 2018 and June 7, 2019.
The time was chosen to be the year's
earliest
sunset near
the December solstice, so the analemma's lowest point just kisses the
unobstructed sea horizon at the left.
Sunsets
arranged
along the horizon toward the right (north)
are centered on the sunset at the September equinox and
end with sunset at
the June solstice.
