Description

An image of Sunday, Feb. 19th, 2023 from Emberger Alm Carinthia.
This was the day with the most massive airglow, I have ever recorded. Visually, it was not visible even to a trained eye, but the RAW images were really soaked in green color. Green to an extent, that I first suspected a technical issue of my camera or some wrong settings. After careful review of all the settings, I am quite sure this is airglow. Even the snow did reflect greenish light and was not bluish as usual.
To make the images somehow viewable, I did reduce the green a tad, not to generate the impression of overemphasizing the airglow.
