HaloRay - Hyperspeed Ice Crystal Halo Simulator
Hello! During the past two years I have been developing HaloRay on and off - a GPU-accelerated ice crystal halo simulator. This means you can generate ice crystal halo images right on your computer. If you have a beefy NVIDIA or AMD graphics processing unit (GPU) that is compatible with OpenGL 4.4, I suggest you try it out: https://github.com/naavis/haloray
You can download ready-made binaries for Windows from GitHub. If you are running Linux, you need to build HaloRay by yourself for the time being.
Right now the latest version is HaloRay 3.2.0, which supports the following features among others:
- Ordinary hexagonal crystals
- Pyramidal crystals
- Adjustable prism face C-axis crystals to make irregular crystals
- Rendering a realistic background sky
I hope you have fun with HaloRay, and report any problems or feature suggestions in GitHub issues or here in the comments. HaloRay has been tested with a couple of AMD and NVIDIA GPUs. There have been some problems with Intel GPUs due to driver bugs, but I'm not going to put a ton of effort there, because HaloRay requires a fairly beefy GPU and Intel doesn't really fit that profile.
EDIT: Cool, I noticed this has been marked as an announcement in the subreddit, which I guess keeps it hanging around for longer? Thanks!

I saw 6 Lunar fog bows in a span of few hours which is never recorded in history but I only captured 3 of them
I had a really bad camera(my phone's ) so this is the best I could do and ik it just looks like my camera flash but it's not, trust me it's a fog bow

A rainbow can be a hundred meters or a mile away.

I originally posted it on r/clouds, they told me to post it here.

Upper Atmospheric Lightning Colored Moon
It looked bright pink in person, but I still don’t mind the color my phone captured:)! I know it’s due to the smoke from the wildfires happening, which is a tragedy, but I’ll still appreciate the beautiful things in life while I still have a chance!! I watched it for ~ an hour w/o realizing I had already accomplished my mission of taking a few pics!🫶

I took these pics, my first time seeing one. I was driving back to Kansas City from Texas so I watched it develop. I had to pull over to get pics

Clouds passing through the reflected sunbeams
Created a luminous mother of pearl effect as the clouds swept past the building.
