Very cool. At the moment it's assuming everything acts like a Starlink in terms of flaring. I'll add in code to differentiate other things (esp ISS) later.Nice. I tried to catch you out by using a non-starlink TLE - the hundred or so brightest satellites - but it worked seamlessly!
Was prompted by this. California, 2/15/2023 02:35 UTC is claimed time. But I'm not seeing Starlinks group like that then - although there is a train in that rough position.
Audio suggests Montecito Heights (Los Angeles)
