On December 24, 2012, a strange double helix cloud was spotted just outside Moscow, Russia. A series of amateur photographs were submitted to a Russian site called netall.ru. While it is not entirely known what caused such a phenomenon, it is believed it may be a contrail. Contrails, short for “condensation trails” or vapor trails are long thin artificial clouds that sometimes form behind an aircraft.

Vapour trail of a Minotaur rocket rocket launched from Vandenberg, AFB twisting in the wind. The pearly colorsare caused by water droplets and bits of unburnt fuel from the rocket’s exhaust freezing in the cold upper atmosphere. When sunlight hits the icy crystals, they glow pastel yellow, red and blue—a phenomenon known as iridescence.

Fallstreak hole phenomenon or hole punch cloud over Novokosino, Moscow, Russia. Such holes can appear in cirrocumulus or altocumulus clouds, they are formed when the water temperature in the clouds is below freezing but the water has not frozen yet causing the water droplets around the crystals to evaporate: this leaves a large, often circular, hole in the cloud.
