Noctilucent clouds #1

This week I was out with my camera to catch the first auroras of the season. While the aurora was still faint due to the long summer nights, I saw finally some noctilucent clouds for the very first time. It was an electric sight, seeing those clouds lighting up the sky. Here are some facts I picked up from wikipedia:

Noctilucent clouds are visible in deep twilight only, when sunlight is illuminating the tiny crystals of water ice from below the horizon. This happens only when the sun is somewhere between -6° and -16°. Located in the mesosphere at altitudes of around 80 kilometres, NLCs are the highest clouds in Earth’s atmosphere. Noctilucent roughly means ‘night shining’ in Latin.”
