My site has this but only for satellites. https://james.darpinian.com/satellites/ For OP I'd suggest doing calendar events for notifications rather than Web Push. Web Push is very difficult to set up, users are suspicious of it, and it doesn't guarantee timely delivery on Android devices. Calendar events work well on mobile. - Source: Hacker News / about 2 months ago
I bet it is used in a lot of ways people don't notice. In my site[1] I use wasm to run an ancient piece of code called SGP4, but it's totally invisible to the user. Someone actually ported SGP4 to JavaScript but it's slower and doesn't perfectly match the original, so it's great to have the option to run the real C version (actually the original is Fortran but the C port is the standard these days).

The Heavens Above site will give predictions of satellite passes based on location and time, and will predict brightness as well. For example, here's a guess at the 501 location for last night (you might have to set the date yourself). Looks like the SL-16 R/B satellite or the Resurs 01 rocket stage are good candidates; they're about the right time and direction. If you knew time, location, and/or direction more...

Also worth noting: https://heavens-above.com/main.aspx But this has a much nicer UI/UX! The street view rendering is particularly impressive. - Source: Hacker News / about 3 years ago
I have seen planes where they look like just flashes of lights until you get into a really dark place and can see the lights that are always on. I think they fly at higher altitudes for faster, more efficient travel. There are a couple of ways to check into this, though. Heavens-Above tracks satellites and flightradar24 has a playback function for times going back a week. Source: about 3 years ago
