Hmmm well I hope it's not noticeable because starlink is planning 24 orbital planes with 60 satellites per. With that it's safe to say you could see up to 50 or so of them in a night due to the constellation pattern. That's a lot of flickering and moving light in the sky when coupled with AWS' initiative also. I'm hoping your right but at first glance it doesn't seem great.
Don’t get me wrong, Starlink will be a substantial increase in the number of satellites. But if you don’t notice them now, it probably won’t be overwhelming after.
