Thank you.

If it goes all the way from East to West, how can one run any Starlink there=3F

Does the protection area go from East to West via North, but Starlink
could use East to West via South=3F Or the other way round=3F

Or is the protection band only at certain angles off the ground=3F

I think I get the 37=C2=B0 at Zenit - Zenit +18 and -18.

Thank you=21
