Aurora in Norway 2025, final days

In the remaining days, the clouds increased again, and the aurora activity decreased a bit as well. Only occasionally were we able to make out brighter structures through the cloud cover. Yet on one evening, the aurora appeared in a form I had never experienced before.

To the naked eye, it first looked as though a thin, high layer of clouds lay in front of the stars. The stars shimmered only faintly through, and the sky had a milky gray appearance. But the slow, wide-ranging movement of these structures indicated that they could not be clouds.

In the images, it finally became clear what was barely perceptible to the naked eye: the entire sky glowed in a very faint shade of green, crossed by broad, subtle structures. An extraordinary kind of aurora, completely different from anything I had ever observed before.

Some image sequences from the final days have been compiled into short time-lapse videos here.
