I had a mild jaw-drop moment when it showed my house on a starry night with the satellite passing overhead! Very cool website

It works for me (with FB blocked). I use privacy badger[1] and tried reloading the website after blocking facebook and twitter (by default it blocked cookies)

Amazing, minor nitpick it shows the ISS as visible over Ireland at approx 9pm tonight, pretty bright in Ireland at that time at this time of year, will check and report back if it was visible. Great work, you have amazing talent!

Thanks! ISS is very bright; bright enough that it is sometimes even visible before sunset if you know exactly where to look! It's fun to try to spot it in a bright sky although it can be difficult. Let me know if you find it!

Got a great view of the ISS last night just after sunset, thanks!

It seems there is a bug. I see ISS passing by, then I rotate the view a bit, and suddenly ISS passes again, all within a few seconds.

That isn't a bug, the ISS isn't passing by at that moment, the time it will pass over you is at the top. The looped video is showing you how the ISS will pass over you. It isn't a live feed.

Not sure why it's happening, but ISS passes overhead for me multiple times every few seconds. I'm in India. Firefox 100.

I'm not quite clear on what the issue is. By design the site shows the next satellite to pass over, and it loops every 20 seconds like a looping video as suggested by the seek bar and play/pause button at the bottom. Are you saying that it is looping faster than once every 20 seconds?

This is spendid. I've used other tools to spot the ISS previously, but this one makes it so intuitive. Great job.

Fantastic, 3 minutes after clicking on your website, i was watching the ISS passing by at my window.

Wow this is incredible. Can you add geostationary satellites too?

That seems out of scope for a site dedicated to visible satellite passes. Geostationary satellites are way too far away to be visible, and don't move relative to the observer.

Sorry
Your browser does not support Web Assembly. Please upgrade your web browser. I recommend downloading Chrome.
Its the latest MS Edge, but a handy trick you might be interested in is to use detectable bugs to fingerprint a webbrowser. So Internet Explorer 6 might have a browser detectable javascript bug that 8 didnt have, or a bug might exist in IE but not firefox and if someone changed their browser agent ie firefox pretending to be IE, it was still possible to workout what the browser was and deliver code accordingly. :)
Of course some web browsers could be like looking at A Scanner Darkly character!

Do you have WASM enabled? A cursory search indicates it's not on by default

I know its off, I have lots of things switched off, my point was the message wasnt that useful and one way you could improve the message to guide potential visitors to help them switch it on, if they wanted to, was to use the bug detection to really test if the browser is what it say is before giving the guidance to switch on stuff in a browser. Over engineered perhaps, but still valid.

I suppose technically it's imprecise, but erring towards cautionary rather than suggesting they switch stuff on. Someone comfortable with switching stuff on might go looking for it if they know what's up.
I used to do more precise messages like you're suggesting, but such a make or break feature I'd probably just be vague about it. MS edge incidentally is fine. It does what it does.
The use of workers and WASM is not obvious, but on page load it takes the current orbit parameters for every orbiting satellite that is potentially visible anywhere on Earth and calculates the future position of each satellite every few minutes for the next 5 days, and then checks each future position for visibility from your location (accounting for sun angle, earth occlusion, sky brightness etc), all client side before page load finishes. WASM allows me to use the canonical satellite propagation tools (SGP4, written in ancient C translated from Fortran) and workers let me use multiple cores and not block the UI too much.
