The Night Sky - June 2020

For many observers June is the month when Astronomy takes a bit of a back seat as the nights are short and dominated by twilight. For the next four months, as darkness falls the westward moving sky will be countered by the late summer nights drawing in resulting in the early evening constellations hardly seeming to move at all. The Summer Triangle of Vega, Deneb and Altair remain in almost the same position as soon as they become visible.

Noctilucent clouds

Noctilucent clouds 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.
