Night Shining Clouds over Normandy (France)
Panoramic view of the Noctulescent clouds (NLC) seen on Monday, June 22 (morning) over Normandy, France.
These clouds are made of meteorite particles that burn in the atmosphere and are mixed up with water ice. Evolving at 80 km altitude, in the mesosphere, they are subject to high winds (~ 200 km/h or more) and experience complex effects of air turbulence in the form of "gravity waves"...
Monday morning, their incredible brightness made them visible to the naked eye without any problems, from North-North-West to North-North-East. Their intense "electric" blue color is obvious, as well as a red / pink border, explained by the atmospheric absorption.
This panorama is composed of 2 photos taken with a Canon 700D + Sigma Art 18-35 mm F / 1.8.
4 seconds, F / 2.8, ISO 400
