Quiet aurora arc - 5.3.2017 at 20.49 Laukaa Observation number 61740

Visibility II / V

I started staring at the sky at 8:34 p.m., then only the camera eye saw something greenish. From time to time, the stars dimmed again, brightening again, then I realized the fog was hovering in the air. A very slight hint of the light of the Northern Lights was visible behind the fog, from which the image. At about half past ten, the skyline became clear, but even the repo seemed to be quite a dim haze. Otherwise, the atmosphere is fine, hovering fog in front, clear starry sky behind the crescent moon.
