01/03/2018 – Ephemeris – The year starts out with all the bright planets in the morning sky

January 3, 2018 1 comment

Ephemeris for Wednesday, January 3rd. The Sun will rise at 8:20. It’ll be up for 8 hours and 54 minutes, setting at 5:14. The Moon, 2 days past full, will rise at 7:30 this evening.

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 3:45. It’s approaching Jupiter which will rise 6 minutes later at 3:51. They will cross paths this weekend, I’ll have more on that tomorrow. Mercury will be a challenge to spot, rising in the east-southeast around 6:38 a.m. now. 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.

Morning planets

Three morning planets are visible at 7 this morning. Created using Stellarium.

Jupiter and its moons

Jupiter and three of its four Galilean moons as they might be seen in a telescope at 7 a.m. this morning, January 3, 2018. Created using Cartes du Ciel (Sky Charts).

Event                      UT        EST      
Europa Eclipse starts:    7:51
Io Eclipse starts:        8:35
Io Occultation ends:     11:45    6:45 a.m.
Europa Occultation ends: 12:12    7:12 a.m.

Only the last two events will be visible in the Grand Traverse area.  Occultations now have the moon enter Jupiter’s shadow to the west, then unseen pass behind the planet to emerge at the east edge of the planet.

Binocular Moon

The only bright solar system object visible in the evening is the waning gibbous Moon. Binoculars will reveal several large craters. this evening January 3, 2018. Created using Stellarium.

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.

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.

Let’s take our weekly look at the bright planets. 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..

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

11/13/2017 – Ephemeris – Close conjunction of Venus and Jupiter is visible this morning

November 13, 2017 1 comment

Ephemeris for Monday, November 13th. The Sun will rise at 7:36. It’ll be up for 9 hours and 39 minutes, setting at 5:16. The Moon, 3 days past last quarter, will rise at 3:26 tomorrow morning.

This morning the planets Venus and Jupiter will appear a bit less than the moon apart after rising at 6:22 a.m. Venus is heading back to the Sun, actually around the back of the Sun. Jupiter is separating itself from the Sun. The velocity of a planet in its orbit decreases the farther from the Sun it is. This was discovered by Johannes Kepler back in he 17th century. Venus is closer to the Sun than the Earth, so after it passed the Earth back on March 25th passing between us and the Sun. It moved ahead of us reaching its greatest western separation from the Sun on June 3rd, is now heading around the bend, so to speak, behind the Sun, on January 9th. The Earth moves faster than Jupiter, so it is appearing to move away from the Sun.

11/12/2017 – Ephemeris Extra – Venus and Jupiter will appear together tomorrow morning

November 12, 2017 1 comment

Just a quick note.  I’ll talk about it in more detail tomorrow on the program, but this post will get you a full day heads up.  Venus and Jupiter have been approaching one another, at least from the Earth’s point of view for some time.  Monday morning their path’s will seem to cross, with Jupiter heading away from the Sun and Venus heading toward the Sun.
