10/04/2017 – Ephemeris – Where are the bright planets tonight?

October 4, 2017

Ephemeris for Wednesday, October 4th. The Sun will rise at 7:44. It’ll be up for 11 hours and 32 minutes, setting at 7:17. The Moon, 1 day before full, will set at 7:21 tomorrow morning.

Let’s take our weekly look at the bright planets. Jupiter, for all intents and purposes is gone from the evening sky. It will cross into the morning sky later this month. Saturn too is sinking lower in the southwestern sky in the evening. Saturn’s rings are still spectacular in telescopes, but since Saturn is so low in the sky the turbulence of the thick atmosphere makes Saturn fuzzy and seemingly to go in and out of focus. Saturn will set at 10:43 p.m.

In the morning sky, brilliant Venus will rise at 5:11 a.m. in the east with much dimmer Mars below and right of it by half the width of the Moon. Mars is less than 100th the brightness of Venus, and will probably require binoculars to locate. (need a few words more)

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

Members of the Grand Traverse Astronomical Society and I are invited to the Chinese Mid-Autumn Festival being held for the Chinese exchange students in the Traverse City school system.  Its held on the 15th day of the 8th month of the Chinese lunar calendar, the full moon, which works out to be October 4th this year.  They will be having Chinese food and viewing the Moon afterward.

One of the legends celebrated then will be the Jade Rabbit pounding medicine.  Jade Rabbit (Yutu) is the name of the Chinese rover that’s on the Moon.  And the Jade Rabbit can actually be seen on the Moon:

I hope they have Moon Cakes.  They sound yummy.

Planets and the Moon on a single night

Planets at sunset and sunrise of a single night starting with sunset on the right on October 4, 2017. The night ends on the left with sunrise on the 5th. The full Moon has fallen in the cracks between the sunset and sunrise charts due to its position south of the ecliptic. Click on the image to enlarge. Created using my LookingUp program.
