that such a skinny Cb cloud still can produce relatively many lightning strikes... I have seen this once near the island of Stromboli, albeit with less lightning, but still. Perhaps this is favored because of the warm moist weather, making it easier. Normally, a skinny cloud like that over Scandinavia wouldn't have much of a chance to produce lightning.
MORE POLAR STRATOSPHERIC CLOUDS: For the third day in a row, Arctic sky watchers are reporting a widespread outbreak of polar stratospheric clouds. "The colors are spectacular," says Ramune Sapailaite, who photographed the display over Gran, Norway:

"The clouds were visible in the sky all day, but the colors really exploded just before sunset," says Sapailaite. "I took these pictures using my cellphone."

Widely considered to be the most beautiful clouds on Earth, polar stratospheric clouds (PSCs) are rare. Earth's stratosphere is very dry and, normally, it has no clouds at all. PSCs form when the temperature in the Arctic stratosphere drops to a staggeringly-low -85 C. Then, and only then, can widely-spaced water molecules begin to coalesce into tiny ice crystals. High-altitude sunlight shining through the crystals creates intense iridescent colors that rival auroras.

During a typical Arctic winter, PSCs appear no more than a handful of times, and the first sightings usually come in January. This week's apparition marks an early start, and may herald many more PSCs to come.

Also known as nacreous clouds or mother-of-pearl clouds, PSCs are a type of atmospheric phenomenon that occurs in the winter polar stratosphere at altitudes of 15,000 to 25,000 meters.


Ice Age is coming
Polar stratospheric clouds, also called pearly clouds or mother-of-pearl clouds, are clouds characterized by their colorful pastel shades. Composed of tiny ice crystals, they form between 15 and 30 kilometers above sea level at temperatures of about -83 °C.

Skypunch cloud in Tuxtla Gutierrez Chiapas, Mexico


A fallstreak hole (also known as a cavum, hole punch cloud, punch hole cloud, skypunch, cloud canal or cloud hole) is a large gap, usually circular or elliptical, that can appear in cirrocumulus or altocumulus clouds. The holes are caused by supercooled water in the clouds suddenly evaporating or freezing, and may be triggered by passing aircraft. Wikipedia​

The circumzenithal arc, also called the circumzenith arc (CZA), upside-down rainbow, and the Bravais arc, is an optical phenomenon similar in appearance to a rainbow, but belonging to the family of halos arising from refraction of sunlight through ice crystals, generally in cirrus or cirrostratus clouds, rather than from raindrops. The arc is located at a considerable distance (approximately 46°) above the observed Sun and at most forms a quarter of a circle centered on the zenith. It has been called "a smile in the sky", its first impression being that of an upside-down rainbow. The CZA is one of the brightest and most colorful members of the halo family. Its colors, ranging from violet on top to red at the bottom, are purer than those of a rainbow because there is much less overlap in their formation. Wikipedia
Shock Unleashed by Celestial Presence of Humanoid Figure in Juarez and Cadereyta, Mexico

Celestial Presence of Humanoid Figure in Juárez and Cadereyta Sparks Commotion
The sight of an individual in the clouds generated speculation about the possibility of being a Horseman of the Apocalypse.

The sighting of a humanoid figure in the sky of northern Nuevo Leon, especially visible in Juarez and Cadereyta, sowed fear and uncertainty.

The image of what appears to be a man walking among the clouds went viral on social networks, taking advantage of the clarity of the day around 18:00 hours.

"From the Bella Vista neighborhood this is what the sky of my Cadereyta looked like. Many say it resembles a Horseman of the Apocalypse", local media reported.

Despite the concern it could generate, some found an explanation that seems logical.

"We are facing pareidolia, a psychological phenomenon in which people identify meaningful patterns, such as faces or bodies, attributing them to an object or landscape," a Facebook user shared, adding that it is a process of brain decoding that transforms information into an understandable response.
