👉 Please consider supporting my channel by buying us a virtual coffee at: Yesterday (17th of January 2022), the northern regions of Scandinavia were treated to a very rare high-altitude spectacle. For about 2 hours, rare polar stratospheric clouds (PSC) type II appeared out of nowhere, displaying a staggering iridescence contrasting with the dimmer twilight of the short polar days. PSCs are also called mother-of-pearl clouds or nacreous clouds because their iridescence (diffraction of sunlight in tiny ice particles) is some of the strongest in clouds on Earth. Their strong colors are very visible with naked eyes, making the experience surreal, almost straight out of a fairy tale.
