I admit this question is derived from a science fiction scenario, but I’m wondering what that actual astronomical terminogy would be here.
Assume you’re standing on a moon orbiting a gas giant. The moon is both tidally locked and in geostationary orbit, so if you look straight up, you’re always staring into a same storm raging on the planet below.
Each day on this moon is divided into four phases, and here’s where my question lie. As a layman, I refer to these phases as:
Morning: You get some oblique direct sunlight as the sun rises from your horizon before passing behind the gas giant.
False Day: The moon falls into total eclipse. Pretty dark, I assume.
Sunset: More oblique direct sunlight as the sun emerges from the gas giant before setting below your lunar horizon.
False Night: The sun is now below your horizon (but I assume you’re getting some twilight reflected off the gas giant filling your sky.
So, do these day-night-phases have actual technical terms?
