From late May through July, one of the most dynamic and beautiful spectacles can be seen in the night sky from mid latitudes. The shimmering iridescence of Noctilucent Clouds (NLCs) is worth getting out to watch and they're easy to photograph.

Derived from the Latin for "night-shining", noctilucent clouds usually resemble luminous, silvery cirrus clouds (the wispy ones) and start to appear in the north west to north shortly after sunset as the sky begins to get dark enough to see the brighter stars. 2/25 
As dusk deepens, NLCs appear to get brighter and cover a larger part of the sky - it's not uncommon for them to stretch overhead during a strong display. Displays can last from a few minutes to hours and even all night. 3/25
