Explanation:
Near a summer's midnight a mist haunts the river bank in this
dreamlike skyscape
taken on July 3rd from northern Denmark.
Reddened light from the Sun a little below the horizon
gives an eerie tint to low hanging clouds.
Formed near the edge of space, the silvery apparitions above them
are noctilucent or night shining clouds.
The icy condensations on
meteoric
dust or volcanic ash are still in
full sunlight at the extreme altitudes of
the
mesophere.
Usually seen at high latitudes in summer months,
wide
spread displays of the noctilucent clouds are now being reported.
