Visibility III / V
The detection is from an infrared-detecting fireball camera. The Watec camera has a filter that allows a longer wavelength to pass through approximately the visible boundaries.
Of course, it doesn't give spectacular color images, but it's actually good to detect northern lights quite far away at low altitudes, because the sky is dark even in light pollution and in the moonlight, and the absorption (extinction) into the atmosphere is low even at low altitudes. Appeared remarkably active in only three 2-minute peakhold images, and the timing reported is also from this vibe. Before that, a calm northern lights belt was visible for even longer. I guess this episode is about to end.
