Ice Halos by Moonlight and Sunlight

Explanation:
Both Moon and Sun create beautiful ice halos in planet Earth's sky. In fact, the two brightest celestial beacons are each surrounded by a complex of ice halos in these photos of the sky above Chamonix-Mont-Blanc in France. The panels were recorded one night (left) and the following day at the end of December 2025. Similar ice halos appear in moonlight and sunlight because they are all formed through the geometry of flat, hexagonal ice crystals. The ice crystals reflect and refract light as they flutter in the cold atmosphere above the mountain resort. In the pictures both Moon and Sun are surrounded by a more commonly seen 22 degree circular halo. Bright and sometimes colorful patches at the intersections of the 22 degree circular halos with the indicated parselenic and parhelic arcs are also known as Moon dogs and Sun dogs.

Cet après-midi, une promeneuse m'a demandé ce que je photographiais alors que je prenais ce cliché au début de mon tour quasi quotidien...
Je ne sais pas depuis combien de temps il y avait cette #irisation dans les nuages autour du #soleil avant que je ne m'en aperçoive, mais le temps de répondre à la promeneuse, c'était déjà vraiment moins évident à voir. Et ce fut le seul cliché.

This afternoon, a woman out for a walk asked me what I was photographing as I was taking this shot at the start of my almost daily walk...

Catching up on the #halo series. It bats above average for a video game adaptation!

This season was strongest up through the Fall of Reach and then dragged a bit with the search for Kessler and the political machinations, though I enjoyed Perez and the Spartan-IIIs and the final approach to the Halo.

Not surprised to see the Flood getting set up for a third season that never was, even as they killed off most of the characters.

Mostly makes me want to go back and play the game campaigns
