The Starlink satellites are reported to already be intrusive for observers
at high latitudes.

Contrary to expectations, they are bright and visible all night at this time of year at our latitudes. Neat sight now, but imagine the sky littered with hundreds of these all the time, at any one time.

While most of the few dozen satellites were faint on this pass 4 were quite bright, and easily naked eye, and similar to the Big Dipper stars in magnitude. Polaris is at lower right at the end of the Little Dipper handle.

This is a frame grab from a 4K video at ISO 52000 with the Sony a7III and Canon 24mm lens at f/1.4. I stacked 8 frames to smooth noise but the satellites themselves are from one frame to keep them point like. Taking a longer-exposure still image at a lower ISO was not an option here as the moving satellites would have blurred into a streak looking much like any single satellite trail. So taking a video at an ultra-high ISO speed, then extracting still frames was the method of choice though it produces a noisy image.

Here's my real-time video of two of last night's Starlink satellite train passages. These give you a good idea of what they looked like to the naked eye.

Yes, they are bright and can be seen all night, not just at dusk or dawn. Surprise SpaceX! Do your homework on lighting geometry at solstice.

They are a novelty now, but will be a desecration of the "dark sacred night" when there are thousands of these things up there. Manmade junk will outnumber the stars.
