A 54km ride this evening, half of which was along a new route 🙂

Which my ELEMNT recorded & which shows in my weekly ride total, but the ride itself has disappeared from the gizmo & did not sync to my phone or to Strava. Will have to add it manually 🙄

Only little spits of rain during the ride, but as this 22° halo & outer elliptical circumscribed halo from earlier in the day show, the weather is a changin’ 🌧️

Tree sex makes colored rings in the sky – Yesterday, I observed pollen coronas around the sun and the moon.

These colorful rings appear around the sun / the moon when airborne pollen diffracts the light (=deflects it depending on its color).

Different pollen types make different coronas. Here, it is likely pine pollen.

Very nice pollen based atmospheric optics.

Last night I observed a pollen corona around the bright moon. These colored rings around the moon are created when its light is refracted by airborne pollen.

Depending on the type of pollen, different ring shapes and sizes appear. This one is probably from pine pollen.

Today, an hour before sunrise, I noticed a bright, unusually structured cloud in the eastern morning sky (location: north of Hannover, Germany). I took photos between 6:40 CET (solar elevation -8°) and 6:55 CET (solar elevation -5.8°) while the cloud was slowly fading.

Apparently there was a rocket reentry last night, which was seen and filmed over Germany. Perhaps the cloud is its remnant?

Not something you see every day 😱

Anti-crepuscular rays above & below the eastern horizon, converging on the anti-solar point at the end of the shadow being cast by an airplane’s contrail.

Cast by clouds on the other horizon near sunset, these rays are actually parallel, but perspective makes them converge like railway lines.

Normally they’re only see above the horizon for obvious reasons 😉

As seen from LH754 en-route to Bengaluru last night ✈️

Ok, Mastodon, do your thing. Does anyone know what happened with atoptics.co.uk? It used to be this gorgeous website with lovely explanations about optical phenomena in the atmosphere and an "atmospheric optics picture of the day" to which I subscribed. Now all of it its gone and the only thing left is a plain and boring-looking blog with almost no pictures and ai-feeling text that hasn't been updated in a year.

Please boost!
