The Night Sky - June 2020
High Lights of the Month
Noctilucent clouds also known as polar mesospheric clouds are most commonly seen in the deep twilight towards the north from our latitude. They are the highest clouds in the atmosphere at heights of around 80 km or 50 miles. Normally too faint to be seen they are visible when illuminated by sunlight from below the northern horizon whilst the lower parts of the atmosphere are in shadow. So on a clear dark night as light is draining from the north western sky after sunset take a look towards the north and you might just spot them.
