Unusual Radar Echoes Detected as Noctilucent Clouds Intensify

Source - Space Weather News for May 28, 2015: http://spaceweather.com

Last week, Earth-orbiting satellites detected the first noctilucent clouds of the 2015 season.  Now people on Earth are seeing them, too.  Photographers in Scotland recorded a fairly bright display of the electric-blue clouds on May 28th.  At the same time, radars have detected intense echoes coming from the "noctilucent zone" 80 km to 90 km above Earth's surface--possibly coming from the clouds themselves.
