I like to go out on the Broads after sunset and shut off the engine and lights and look UP at the stars. Sometimes you can even see Satellites, Shooting Stars and maybe even the Space Station fly by. Satellites look like stars, but move across the sky, and they don't twinkle like stars.
Running lights (strobes) on high flying planes usually flash so you can identify and differentiate them from satellites. If it shows a wake or tail it's a shooting star or meteor.
Be prepared to turn your lights ON if a boat looks like it may pass close to your position. I've always wondered what the correct lights to display should be when
Drifting at night. You're not anchored so that's out. You're not underway so the running lights don't seem correct.
I think
Drifting at night without lights is a probably a
Punishable Criminal Offense...Totally
