What is this red stuff showing up in my photos? Red airglow? Auroral glow? There is a geomagnetic storm in progress. The shot is from the summit of Mauna Kea looking south! Also visible is the glow of the lava lake at Halemaʻumaʻu and a research laser shining up from the NOAA atmospheric lab atop Mauna Loa. Canon 6D and 14mm f/2.8 lens, 30s at ISO 6400.

It is red airglow for sure, nice capture!!! Airglow depends on extreme UV radiation of the Sun, and as the solar activity is high the UV is also high. I love you pic!

It turns out that intense tropical airglow may indeed be related to geomagnetic events. This display was out of all proportion to conditions before or after the event. There are a couple papers of systematic observations over tropical location like Puerto Rico that show a relationship.
