what my eyes see in the pic:
cyan (only in some places, must be an accessory bottom or belly part of an ionosphere wave) to green to yellow to orange to red to magenta
what I read:
95 km high, faint blue range glow
emitted by O₂ molecules;
90 to 100 km high, 558 nm, green
emitted by neutral O atoms. Below an excited O atom that takes about 0.7 second to decay to another lower energy excited state is too often kicked by an N₂ molecule instead; moreover the extreme UV sunlight is less intense and there are fewer oxygen atoms
some 5 km within 80 to 105 km range, 589.2 nm, yellow-orange
emitted by neutral Na atoms in a 5 km thick layer (rather thin). Higher up it's Na⁺ ions, lower down it's Na₂O and other molecules. Nowdays this
sodium layer is used for
laser guide stars at leading-edge observatories;
150 to 300 km high, 630 nm, red
emitted by neutral O atoms in another excited state. Below an excited O atom that takes about 107 seconds to decay to another lower energy excited state is too often kicked instead.
There is a mismatch: the red thick top is missing and a magenta top can be seen instead. Is it just visual merge with a blue bottom of another wave beside?
