This movie has recorded the diurnal motion of rising Milky Way on a night of beginning of summer. In the first half of the movie, you can see dimmed and greenish stripes are crossing the whole of sky from west to east slowly. The light has been called the "Nightglow", from the emission of activated high-altitude atmospheric molecular. The light of nightglow looks extraordinary dim, in that night I could not detect with naked eyes.
