Scotland is best because its northerly aspect means launches pass over the sea, and not over inhabited areas.
Sun-synchronous orbits (inclined at near 98°) are valuable for Earth surveying missions.

Re: Heads up
Prediction fulfilled. Not able to give a direction, as at the time of my message, Landsat 9 was still on the launch pad.

Re: An unseasonable query
I did spot a naked-eye star between the horns on June 10. It's called "The Sun"; it was accompanied by the Moon.
Re: Sun Dog
No, that's when the sundog is so intensely bright that its causes an arc of light in rainfall on the opposite
side of the sky. It is offset by 22° from the rainbow caused by normal sunlight.

Re: Losing the Night Sky
Your data is clearly based on the "Chicken Little" hypothesis.
Last night I observed 17 Starlinks, only one of which (19-74AF) reached a magnitude of +3.5
The others had magnitudes clustered around +6 - just one-tenth of the brightness of your
scaremongering prediction.
