Other During a solar eclipse, something incredible happens under the trees: the gaps between the leaves project small images of the eclipse onto the ground.

two seperate events that i was lucky enough to witness, both seen from central sweden near ski resorts, with snow cannons running.

did my best to try and indentify all of the different halos visible in these images, although i'm by no means knowlegdeable enough to say what some of them are with absolute certainty, so feel free to correct me if i got something wrong (or missed something!).

image 1, 2, 3 - halo display from november 18th 2023, sun's altitude: ~4.5°

seems to include:

image 4, 5 - lunar halo display from december 4th 2025, moon's altitude: ~51°

bonus image - massive artificial light pillars from the same day
