Details:
It was clear last night in the evening so I was out stargazing. There was a noticeable brightness in the air and I had a strong hunch that there was some neon green airglow that would appear in my camera. After snagging a few planetaries in the 12” dob, I set out to capture some photos. Voila! Green green glow. It was all over the sky, though it seemed a little stronger towards the south. I also saw some faint ripple structure, especially towards the northeast. I broke out my SQM-L meter and got an average of about 21.50 mpsas, which is actually fairly dark, but about 0.15-0.25 mpsas brighter than I would expect at this time of the year. This all happened from around 11pm to midnight MT on April 28th (6:00 UTC April 29) Also of note, the solar activity had been fairly quiet for at least the past day or two. Nikon D750, 20 sec exposure at iso 3200 f2.8. 14mm lens postprocessed in Lightroom - West Elk Mountains of Colorado.
