'Extremely rare' noctilucent clouds that make midnight look like sunset light up night sky over Sheffield
and live on Freeview channel 276
Several photographers last night captured these stunning photos of what appears to have been an “extremely rare” weather phenomenon that lit up Sheffield’s sky - noctilucent clouds.
The striking nighttime event is caused by collections of ice crystals, which at around 200,000 feet above ground are so high up they are still reflecting sunlight even at night.

They become visible about the same time as the brightest stars and are usually bluish or silvery.”
It seems a perfect fit to describe these two late night pictures by Linda Slack and Billy Wassell from after midnight on June 18 in Sheffield.
