Telescopic planets

Venus, Jupiter, Saturn and Mars with the same magnification at 10 p.m. August 15, 2018. Jupiter’s satellite label Io is shown. However at 10 p.m. it’s occulted by Jupiter. The occultation began at 9:35 p.m. EDT (01:35 UT the 16th) and will emerge from Jupiter’s shadow at 1:02 a.m. EDT (05:02 UT) after Jupiter sets locally. Mars is also shown enlarged. It seems that the global dust storm is abating, so the albedo features are beginning to be seen. Created using Cartes du Ciel (Sky Charts)
