The sky lights up in greens and reds from aurora and airglow.
This has been a good week for aurora watching. Friday night the Northern Lights danced again, this time in a sky already filled with a more subtle phenomenon, airglow.
Airglow adds its own bands of reds and greens across the sky, seen here as arcs from left (west) to centre (north) and into the east. Airglow is light from fluorescing air molecules releasing energy absorbed from the Sun by day.
The aurora adds the brighter green curtains across the north with vertical beams of yellow and red shooting up.
A weird structure which I assume is from the aurora is the sharp-edged yellow band at left in the west. It lasted no more than 2 or 3 minutes, enough to record in three frames of this 7-segment 180° panorama taken near home at an array of grain bins, now filled from the harvest.
To the west and east urban light pollution adds glows of yellow to the horizon.

Nice composition on this image!
Thanks! I wish I had got set up a little earlier to catch the Aurora when it was at its best. It was dying down at thus point.
