Just eight days ago, I gave a popular science talk at @mpi_grav about colorful phenomena in the sky, and now – boom!
Just minutes ago, there were beautiful iridescent clouds (https://en.wikipedia.org/wiki/Cloud_iridescence) here, north of Hanover, Germany.
Here, light is diffracted by tiny droplets in the clouds, creating these typical mother-of-pearl colors.

There is currently a halo (22° halo, https://en.wikipedia.org/wiki/22%C2%B0_halo) around the moon.
The ring is created by moonlight refracted by hexagonal, non-oriented ice crystals. These ice prisms are found in high-altitude clouds (cirrus clouds). This type of halo is quite common. Its radius is 22°, which is about 44 full moon diameters.

Regenbogenfragment bei tiefem Sonnenstand heute früh 10 min nach Sonnenaufgang. Der Regen zog in der Entfernung schnell durch, das Regenbogenstück war nur wenige Minuten lang zu sehen

That was a really bright rainbow just before sunset when a heavy shower passed over Wedemark.

Fata morgana visible today, from Willows Beach in #OakBay, #VictoriaBC. Cold air under warm creates a duct where there are multiple paths that light from an object can follow to your eye. The different paths result in multiple images of the same thing. In the image of the ship, it's heat haze, small pockets of convection mixing the cold and warm air, that result in a smearing of the image. It's very painterly.
La Lune ne change pas, c’est l’air qui joue des tours à sa lumière. Horizon bas, poussières : bonjour reflets rouges.

A stunning display of noctilucent clouds over Vallentuna Lake, Sweden, captured on July 10. These night-shining clouds form 80 km above Earth and glow in twilight by reflecting sunlight from beyond the horizon.

Two different sets of #IridescentVapourTrails captured from Oxfordshire, UK 15 June '25 The colours are created when sunlight is diffracted by tiny water droplets that condense out over the aircraft wings. Canon 1100D + 300mm zoom lens #AtmosphericOptics #Aviation #Diffraction
As the almost #FullMoon rose on 11th June 2025, it created the tallest #MoonPillar I've ever seen, extending about 30 degrees up! Photographed from North Oxfordshire with a Canon 1100D + Sigma 300mm lens #AtmosphericOptics
Currently doing battle with a truculent million year old baby protostar below the belt of Orion, moving behind clouds some eighty million au away 😬
As a brief distraction, here’s a several billion year old grown-up star just one au away, playing with the water and ice in the atmosphere of one of its planets 🌞

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’ 🌧️
One additional image of the rising Moon with a pine pollen corona. It was quite easy to see with the unaided eye.
This was taken on May 12 at 22:26 CEST north of Hanover, Germany.
3.2 seconds exposed at f/6.3, ISO 640 and f=200 mm.

Did you know that you can observe fascinating #mirages in the Black Forest? In my latest blog post, I explore this phenomenon of #AtmosphericOptics and share my personal observations from the coast of the English Channel and the mountains of the Black Forest.

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.

If you expose the image more (here the same conditions as before, but t=1.3 seconds), you can see the typical multiple diffraction rings.

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.

I spotted a very clear 22º halo today. This is caused by hexagonal cylinders of ice, tiny crystals, suspended with their long axis roughly perpendicular to the rays from the sun. Refraction splits sunlight into colours and diffraction forms the ring. There's also the suggestion of the circumscribed halo. This #halo is oval, centred on the sun, and meets the 22º halo above and below the sun.
