Earth Science Picture of the DAY (EPOD) for 9.7.2023 features a type of airglow, a phenomenon that I've never seen or heard of with respect to the Milkyway. It is something I'd love to see just once but don't expect I will. Much of what is above me is a victim of what I call "cityglow."

Observer and photographer Soumyadeep Mukerjee describes his unlikely-to-be-forgotten experience upon seeing for the first time and its causes, in a sky where chemistry and physics rule.

The Wiki entry on airglow or nightglow gives an idea of its range. I have noticed some of them before but never the one Mukherjee brought to the attention of EPOD viewers.
