September 18, 2019 Leave a comment

Ephemeris for Wednesday, September 18th. Today the Sun will be up for 12 hours and 23 minutes, setting at 7:48, and it will rise tomorrow at 7:26. The Moon, 3 days before last quarter, will rise at 10:11 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 low in the 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 Jupiter’s Galilean satellites can be easily spotted in telescopes this evening. The moon Europa will appear very close to the planet. Jupiter will set at 11:21 p.m. Saturn, the ringed planet, will be in the southern sky in the evening. It will pass the meridian, due south at 8:52 p.m. and will set at 1:19 a.m.

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

09/03/2019 – Ephemeris – Yesterday and today conjunctions of Mars and Mercury with the Sun

September 3, 2019 Comments off

Ephemeris for Tuesday, September 3rd. Today the Sun will be up for 13 hours and 8 minutes, setting at 8:16, and it will rise tomorrow at 7:08. The Moon, 2 days before first quarter, will set at 10:59 this evening.

Yesterday morning Mars passed in conjunction with the Sun. For astronomers Mars was either just north or south of the Sun. In this case it was north of the Sun, moving from the evening or east side of the Sun to the west or morning side. Later this evening Mercury will pass in superior conjunction with the Sun. Mercury, being an inferior planet, that is one whose orbit is within Earth’s orbit of the Sun can pass between the Earth and the Sun in what we call an inferior conjunction or around the back side of the Sun in superior conjunction. In doing so Mercury is moving from the morning to the evening sky. Today the SOHO satellite will show both planets, the Sun and even Venus in its coronagraph.

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