Hi Mike,
I’ve been getting these on my video meteor cameras, just as you describe – a series of satellite flares from the same location in the sky. To be honest, I haven’t checked their identity, whether Starlink or otherwise (e.g. on Heavens Above). These flares, and the processions of satellite chains, are becoming so common I often delete the video clips, although I have saved a couple for presentation purposes.
Oh the joys of the modern Vermin of the Skies.
Cheers,
Alex
