I was amazed to see that there is barely a mention of HamClock on HN (just a single comment).
HamClock is a free C app, it runs on basically anything, that displays a map of the world along with various customizable information panels. Obviously the intent is for amateur radio enthusiasts to use it (and we do) but it's just a lot of fun and very interesting to have a HamClock running on a spare monitor. The different panels include various Sun-related data (sun spots, solar flux, wind), Earth data (planetary Kp), space weather, radio stuff (band propagation, band reliability predictions), aurora predictions, its almost endless.
The map options are similarly [almost] endless. You can even track satellites.
There's a really great blogpost[0] which goes into more of its usefulness (the Clear Sky site is rather dry) including screenshots.
You can run it interactively as a GUI app on basically any platform, or just headless and it will listen in various modes (RO or RW etc) on http ports. There's no SSL but i just put mine behind a reverse proxy.
It's a really great app, not open source, but it is freely available. Was released in 2017, and there's also a good article (updated recently) written by the author of the software[1].
Do yourself a favor, download and compile HamClock and play around. I am not affiliated with the software or Clear Sky, i just use it and like it.
It's a really great app, not open source, but it is freely available.
The client-side application is open-source -- there's a tarball available on the website, and it contains an MIT license. But it apparently depends on a closed-source backend service.

I'm fairly confident this could run off the Internet Archive's emulation support if someone wanted to put the effort in.
