09/04/2019 – Ephemeris – Looking for the bright planets this week

September 4, 2019

Ephemeris for Wednesday, September 4th. Today the Sun will be up for 13 hours and 5 minutes, setting at 8:14, and it will rise tomorrow at 7:09. The Moon, 1 day before first quarter, will set at 11:32 this evening.

Let’s look at the planets for this week. Mars, Venus and Mercury are too close to the Sun to be seen. Venus and Mercury are on the evening or east side of the Sun, Mars is on the west or morning side. Bright Jupiter will be in the south-southwestern sky as it gets dark. With steadily held binoculars a few of the 4 largest satellites of Jupiter can be seen. Three of the four of Jupiter’s Galilean satellites can be spotted in telescopes early this evening tonight. However the innermost moon Io will move from in front of the planet at 10:15 p.m. Jupiter will set at 12:11 a.m. Saturn, the ringed planet, will be in the southern sky in the evening. It will pass the meridian, due south at 9:48 p.m. and will set at 2:14 a.m.

The times given are for the Traverse City/Interlochen area of Michigan. They may be different for your location.

Telescopic planets

Telescopic views of Jupiter and Saturn with the same magnification at 10 p.m. September 4, 2019. Io started a transit at 8:03 p.m. or 0:03 tomorrow UT, not visible from here. The shadow begins to cross Jupiter at 9:21 p.m., 01:21 UT. The transit ends at 10:15 p.m., 2:15 UT. The shadow leaves the planet at 11:33 p.m., 3:33 UT. The moons are much dimmer than what shows here so spotting the moon and shadow against the face of Jupiter is difficult. The Great Red Spot will cross Jupiter’s central meridian at 10:17 p.m., 2:17 UT.  Created using Cartes du Ciel (Sky Charts).
