Two Shadows seen from outer planet surfaces

[ironman]

I finally can see the shadows of the rings of the outer planets and transiting moons casting their shadows on their surfaces in Stellarium 12.4 after upgrading my video card to a PNY nvidia GEFORCE GT 630. Then I noticed while standing on surfaces of the outer planets Saturn, Uranus; and Neptune. That there were two shadows on their rings, one in the day and the other at night both were 15 or 20 Deg’s off the transit points on the meridian, of coarse the shadow in the daylight shouldn’t exist at all. See screenshots SAT 1 and SAT 2. Screenshot SAT 1 is explanatory.

I’ve been an amateur astronomer for over 40 years now. I will say Stellarium is one of the best and certainly prettiest planetarium software out there by far. So kudos to all of the Stellarium team members around the world.

I failed to mention that the shadow at night is the correct one, and is not exactly opposite or 180 Deg of the Sun. You will see in screenshot SAT 2 the Sun is rising and the shadow is about 25 or 30 Deg from the meridian.
