Salt Flats Aurora
Northern Utah was treated to an extremely rare event, some very subtle Aurora appeared on the early morning of May 11th! We had gone out to the Bonneville Salt Flats to shoot the Milky Way and hopefully get some reflections over the flood salt plane, while shooting exposures to the north we noticed some very subtle pink hues along the horizon with quite vivid airglow throughout. Occasionally I would snap a north exposure to kind of track these colors and in one exposure I managed to catch a slight curtain of the aurora. At first we weren't sure if it truly was aurora, pink and red airglow isn't all that uncommon, upon seeing this sky exposure I was pretty convinced despite the low prediction level by various websites/apps. Last night was a KP 4.67 rating according to my apps.
2 exposure blend for this shot, 1 tracked shot for the sky and 1 untracked foreground shot, both taken with my Nikon Z7 and Sigma Art 40mm. Sky shot is 1 minute at f1.4 and ISO 800, foreground is 1.5 minutes at f1.8 and ISO 800.
