Visibility IV / V
I was photographing the northern lights in Sodankylä's Boss Cairo at the top of the Tunturipäät fell, when my attention was drawn to a special spot of light in the sky. It looked a bit hazy and I considered it a star cluster, but then I noticed it moving pretty fast. Turbidity and haze are shown in the images by comparison with adjacent stars. Maybe an airplane - however, I’ve never made a similar observation before.
The attached images were taken with a shutter speed of 15 seconds.
