Neo-Clouds Season (NLC, Noctilucent Cloud)
It comes to an end in around 15th August 2015.
Observing tips:
Look west 30 to 60 minutes after sunset when the Sun has dipped 6 degrees to 16 degrees below the horizon. If you see luminous blue-white tendrils spreading across the sky, you may have spotted a Neo-Clouds (Noctilucent cloud).
