Details:
12:30 AM EDT during the peak compression of the G3 geomagnetic storm. Local conditions on the rural plateau were clear and cloudless, though challenged by heavy urban light-pollution scatter from the nearby Hamilton, ON area.
Due to human scotopic vision limits (grayscale rod cell processing), the display presented to the naked eye as a diffuse, white-gray haze. To extract the raw atmospheric data, I locked a manual exposure to integrate the incoming light particles. Post processing required a manual white-balance override, shifting the profile left into the Green Tint axis to filter out the orange urban city light glare.
The sensor isolated the true emerald emission line of excited atmospheric oxygen atoms. The structural architecture shows appear a Corona aligned with local geomagnetic field lines, presenting a distinct parallel perspective illusion of a 'grounded hawk' (converging central hub with wings flaring east/west and parallel vertical pillars striking the horizon as legs) before morphing into a cross-cutting, multi-layered matrix of overlapping bands at substorm peak.
