Explanation: Night skies over northern Sweden can hold some tantalizing sights in August. Gazing toward the Big Dipper, this beautiful northern skyscape captures three of them in a single frame taken last August 12/13. Though receding from northern skies for the season, night shining or noctilucent clouds are hanging just above the horizon. Extreme altitude icy condensations on meteoric dust, they were caught here just below an early apparition of a lovely green auroral band, also shining near the edge of space. The flash of a Perseid meteor near the peak of the annual shower punctuates the scene. In fact, this year's Perseid shower will peak in the coming days, offering a continuing chance for a night sky photographer's hat trick.
