December weather is always a challenge but followup of the binary neutron-star merger S191213g, from & , saw other issues. Likely trails; note how bright compared to another satellite. Sadly will become much more frequent if launch plans go ahead

Fixes are under study, for instance : one satellite from the next Starlink launch will be dark coated, to mitigate the impact for astronomers. If conclusive, Starlink will probably implement the fixes on the future satellites.

Nope. If they occult a star, they mess up the photometry. They're a damn nuisance, dark- or light-coated.

The ocean was always deemed to be so big that one bit of plastic would never hurt anyone. A thousand bits would be lost in the infinity. A few thousand artificial stars surely won't hurt the billions and billions of real ones? We know that this argument is a load of crock.

worth it. just makes the case for more high orbital telescopes.

"Worth it". No, it's not. It's really not.

How do these trails compare to the first batch of starlinks which have been raised to their full orbit hight and spread out to a proper distance?

A few days ago the second batch were 4 or 5 mag brighter than the first (on the same night). Suspect attitude of spacecraft is different during orbit raising phase. Face-to-earth attitude in operational orbit will be fainter

Serious (not snarky) question; how do the starlinks cause light traces after dusk? I would guess, based on the oix shown, that light pollution from sunset made those pictures worthless even without starlink

Several hundred kilometres up satellites are in full sunlight a long time after sunset or before sunrise at ground level. They won't be sunlit during the middle of the night, but they can still effect a significant fraction of the period that's dark enough for astronomy.
