12/27/2017 – Ephemeris – All the bright planets are in the morning sky. However the Moon is in the evening sky.

December 27, 2017 1 comment

Ephemeris for Wednesday, December 27th. The Sun will rise at 8:18. It’ll be up for 8 hours and 50 minutes, setting at 5:08. The Moon, 1 day past first quarter, will set at 2:43 tomorrow morning.

Let’s take our weekly look at the bright planets. While Uranus and Neptune are evening planets, they require binoculars or a telescope to spot. All of the bright naked eye planets are in the morning sky now, However Saturn and Venus, the brightest are too close to the Sun to be seen. At 7 this morning Mars is in the south-southeast while Jupiter is a lot brighter and below and left of it. Mars will rise tomorrow morning at 3:49. It’s approaching Jupiter which will rise 23 minutes later at 4:12. Mercury will be a challenge to spot, rising in the east-southeast at 6:32 a.m. both today and tomorrow. At 7 a.m. It will require a low horizon, binoculars and luck to find. In its next evening appearance in March it will be placed much higher in the sky for the same twilight conditions.

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

12/20/2017 – Ephemeris – All the visible bright planets are in the morning sky

December 20, 2017 1 comment

Ephemeris for Wednesday, December 20th. The Sun will rise at 8:15. It’ll be up for 8 hours and 48 minutes, setting at 5:04. The Moon, 2 days past new, will set at 7:27 this evening.

Let’s take our weekly look at the bright planets. There are no bright planets visible in the evening sky now. While Uranus and Neptune are evening planets, they require binoculars or a telescope to spot. The morning sky is now host to three planets, though Venus, the brightest will rise too close to the Sun to spot. It’s way on the other side of the Sun, and it will pass behind the Sun in superior conjunction January 9th. At 7 this morning Mars is in the southeast while Jupiter is a lot brighter and below and left of it. Mars will rise tomorrow morning at 3:54. It’s approaching Jupiter which will rise 39 minutes later at 4:33. Tomorrow Saturn will be in conjunction with the Sun and will officially enter the morning sky. It will be a month or more before it separates far enough from the Sun to spot in morning twilight.

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

12/06/2017 – Ephemeris – Where did all the evening planets go?

December 6, 2017 1 comment

Ephemeris for Wednesday, December 6th. The Sun will rise at 8:04. It’ll be up for 8 hours and 57 minutes, setting at 5:02. The Moon, 3 days past full, will rise at 8:43 this evening.

Let’s take our weekly look at the bright planets. Saturn and Mercury are very close together, but too low after sunset to spot from up North here. Mercury will set at 5:50, while Saturn will set 9 minutes later. While Uranus and Neptune are evening planets, they require binoculars or a telescope to spot. (This is beyond the scope of this program, which is geared to naked eye observing or easy things to find and observe with binoculars or a small telescope).   The morning sky is now host to three planets, though Venus, the brightest will rise close to sun will rise at 7:24 this morning. It’s way on the other side of the Sun, and it will pass behind the Sun in superior conjunction a month from today. At 7 this morning Jupiter is bright, low in the east-southeast, while Mars, the Red Planet is just left of the brighter star Spica, which has a bluish hue. They are higher than Jupiter and to the southeast. Mars will rise tomorrow morning at 4:03. Jupiter will rise more than an hour later at 5:14.

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

11/22/2017 – Ephemeris – A look at the bright planets for Thanksgiving week

November 22, 2017 Comments off

Ephemeris for Wednesday, November 22nd. The Sun will rise at 7:48. It’ll be up for 9 hours and 19 minutes, setting at 5:08. The Moon, half way from new to first quarter, will set at 8:39 this evening.

Mercury is briefly visible in binoculars in the southwest in the evening, setting at 6:11 p.m., and will reach it’s greatest elongation from the Sun tomorrow evening. Saturn is sinking low in the southwestern sky. Saturn’s rings are still spectacular in telescopes, but since Saturn is so low in the sky the thick atmosphere makes Saturn fuzzy and seemingly to go in and out of focus. Saturn will set at 6:49 p.m. Tomorrow in the morning sky, Mars, heading away from the Sun will rise in the east at 4:11 a.m., Jupiter, also moving away from the Sun, will rise at in the east-southeast at 5:54 a.m., leaving Venus behind after their conjunction 9 days ago, which will rise at 6:47 a.m..

11/08/2017 – Ephemeris – Jupiter becomes visible in the morning (The bright planets this week)

November 8, 2017 1 comment

Ephemeris for Wednesday, November 8th. The Sun will rise at 7:30. It’ll be up for 9 hours and 51 minutes, setting at 5:21. The Moon, 2 days before last quarter, will rise at 9:52 this evening.

Let’s take our weekly look at the bright planets. Saturn is sinking low 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 7:37 p.m. Tomorrow in the morning sky, Mars, heading away from the Sun will rise in the east at 4:20 a.m., Venus, is heading closer to the Sun, will rise at 6:11 in the east-southeast. Jupiter is in the morning sky but lower than Venus, rising in the east-southeast at 6:33. Mercury has moved into the evening sky and will reach it’s greatest elongation from the Sun in 15 days, but will not be easily visible even then.

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