Special stratospheric clouds today. It's nearly midday on Dec 25 and there's no sun here for another few weeks, but we do get these funky clouds that are very high up in the atmosphere which catch the sun from over the horizon.

They often turn a rainbow of pearlescent colours, but mostly today they've been leaning into the Trans colours... because Trans rights are human rights :)

Iridescent vs nacreous clouds:

#Nacreous clouds, also known as polar stratospheric clouds, form at high altitudes in the stratosphere and are known for their vivid colors, especially during twilight. #Iridescent clouds, or irisation, can occur in various types of clouds at lower altitudes and display pastel colors due to the diffraction of light through small water droplets or ice crystals.

Probably. Labelled by author.

This pic from last night show some clouds very similar to nacreous clouds (above the dark cloud band in the pic). This is about 20 minutes after sunset. Normally #nacreous #clouds form at high latitudes, but this is from Cartagena, Colombia, at only 10.4º latitude North. Any expert around knows if this is possible? 🤔
