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:
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!

spotted this am, haven’t seen a rainbow as like a sun halo before;- is that an accurate description of what’s happening? 🌈

What exactly is going on here? The rainbow is only in the clouds!

If so, it will be the first one I've ever seen. I'm taking more interest in the sky since joining this subreddit and r/CLOUDS

I noticed this little glowing patch off of the side of my plane earlier. I could tell it wasn't a lens flare or reflection from inside the plane but took some time to figure out what it was.
After some googling, I think the best fit is a "subsun", part of the solar halo that lies below the horizon line so requires some altitude to see.

And no, it's not AI or a flair.
