This image depicts a nighttime sky over Tromsø, Norway. A prominent, curvilinear band of green aurora borealis dominates the scene, extending from the upper right quadrant, arching downwards through the center, and fading towards the lower left. The sky is dark blue-black, with numerous faint white speckles consistent with stars visible throughout. In the extreme lower-left corner, a thin, vertical, light brown or tan object, possibly a mast or pole, is partially visible, protruding upwards from the frame edge. No people, discernible ground features, or specific actions are present in the frame.
