Chemical Noctilucent Clouds
I don't believe of the theory about the Noctilucent Clouds as:
"Polar stratospheric clouds are a sign of extreme cold. Normally, the stratosphere has no clouds at all. PSCs form when the temperature drops to a staggeringly-low -85 C. Then, and only then, can widely-spaced water molecules in the stratosphere coalesce into tiny ice crystals. When sunlight hits these crystals, they blossom with intense iridescent colors."
Because they still very stable for many hours at different lights as is from the Sun or the Moon. Of course, very lower temperatures are a very important factor but the chemical decompositions from another factors will be possible for make this crystal reflections. In the list of the pictures shared here, the date and the time are part of the information provided by devices that I has used. Another very important factor is that the Color Temperatures measured by Kelvin color system don't fit with this phenomenon.
