Saturn is sinking low in the southwestern sky. It is becoming harder to spot each evening. Tonight it will set at 6:24 p.m. The morning sky is now host to three planets, though Venus, the brightest will rise at 7:03 this morning and will be fighting twilight as it rises. It’s way on the other side of the Sun, and very tiny in telescopes, though nearly fully illuminated. It’s 156 million miles (251 million km) away. First to rise in the morning is Mars which will rise in the east at 4:07 a.m. tomorrow, Jupiter, will follow and rise at 5:34 a.m. tomorrow.

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.

The reddish star Antares is below and right of Saturn before it sets at 9:50 p.m. Saturn’s rings are spectacular in telescopes. With the demise of the Cassini spacecraft orbiting Saturn for the last 13 years, there is no telescope closer to Saturn than yours.

Much dimmer Mars will rise in the east-northeast at 5:46 a.m. Mars will brighten greatly as it approaches us in the next 10 months. Mercury is too close to the glare of the Sun to be spotted.
