Seč magical night memory

Some moments are so magical, that a man has just to wait until he prepare himself to share the feelings with others. This is one of the moments of mine. It was night on 23rd June 2015 and I was, actually, really upset for incredible bad luck with weather the night before. That time the solar activity woke up one of the strongest northern lights of 2015, visible even from the Czech Republic. It was hopelessly overcast. But the very next night, the sky cleared up and despite the rapidly decreasing auroral activity the sky somehow got green tint anyway. It was visible faintly by naked eyes. The ghostly shaped green bands, like brush strokes, appeared somewhere from the east. I knew that I was witness of very special green airglow. Emitted most likely by atoms of oxygen in about 100 km above ground, this natural atmospheric glow was caused by the extreme UV radiation from the Sun in the day, which was followed by this photogenic chemiluminescence in the atmosphere. I didn’t hesitate even a minute, took my camera and went on a beautiful beach of Seč reservoir, with clear view to the direction of east. The light pollution of far cities disturbed this magnificent phenomenon, but not much. Although, not only cities and the airglow caused that the sky was brighter than usually – it was just two days after the summer solstice, meaning no astronomical night from the Czech Republic. So the sky was, actually, deep blue. Staring at the Milky Way, Andromeda galaxy and “fingers” of airglow on the beach with calm summer lake nearby the local yacht-club, that was one of the most magical moment of 2015.
