Noctilucent Clouds

[RichardL]

Hi All,

One more from me... this time Noctilucent clouds!

Noctilucent clouds, or night shinning clouds are composed of very small water ice crystals formed on minute particles of dust, possibly of cosmic origin from micro-meteors. They're only visible during astronomical twilight, and most often observed in the summer months when the sun is between 6 and 16 degrees below the horizon (60-180 minutes) either after sunset or before sunrise.

Observed when the sun was 10 degrees below the horizon at 3:11am 6th July 2018, along with "Capella" the Shepherd's star.
