Explanation:
The night
of June 21 was the shortest night for planet Earth's
northern latitudes, so at latitude 48.9 degrees north,
Paris was no exception.
Still, the
City
of Light had an exceptionally luminous evening.
Its skies were flooded with silvery night shining or noctilucent clouds
after the solstice sunset.
Hovering at the edge of space,
the icy condensations on meteoric dust or volcanic ash are still in full
sunlight at the
extreme
altitudes of the mesophere.
Seen at high latitudes in summer months,
stunning, wide spread displays of
northern noctilucent clouds
are now being reported.
