Ephemeris: 03/25/2026 – Taking our weekly look at the whereabouts of the naked-eye planets
This is Ephemeris for Wednesday, March 25th. Today the Sun will be up for 12 hours and 25 minutes, setting at 8:01, and it will rise tomorrow at 7:34. The Moon, at first quarter today, will set at 4:26 tomorrow morning.
Let’s take our weekly look at the whereabouts of the naked-eye planets. Earlier this morning Saturn passed conjunction with the Sun becoming officially a morning planet. But it’ll be a couple of months before it’s visible in the morning and about seven months before it’s conveniently placed in the evening sky. By 8:30 PM tonight or about a half hour or so after sunset, Venus may be seen very low in the West. Binoculars or a telescope will show a very tiny disc on Venus, because it is pretty much behind the Sun, a good way from us. Over the next 7 months it will be moving closer to us and becoming much larger. Jupiter is the brilliant star-like object more than halfway up in the southwestern sky at 9 PM. Tonight, it’s below and left of the Moon.

Ephemeris: 03/24/2026 – Visibility of the Moon’s features
This is Ephemeris for Tuesday, March 24th. Today the Sun will be up for 12 hours and 22 minutes, setting at 8:00, and it will rise tomorrow at 7:36. The Moon, 1 day before first quarter, will set at 3:31 tomorrow morning.
The Moon, tonight is just a day before first quarter. Its position in the sky is close to where the Sun will be around the 1st day of summer, so it’s quite high in the southwest as it gets dark. It’s a great time to view the Moon with the telescope, in that the moon isn’t too bright, and there are lots of craters showing up due to their shadows. The terminator nearly cuts the Moon in half. It is in this case, the sunrise line creeping across the surface. It is deep morning shadows that help delineate the features. Looking at the limb of the Moon, the curved edge, the craters are hard to spot, because they are under the midday sun, showing no shadows, which makes them very indistinct.

Ephemeris: 03/18/2026 – Taking our weekly look at the whereabouts of the naked-eye planets
This is Ephemeris for Wednesday, March 18th. Today the Sun will be up for 12 hours and 3 minutes, setting at 7:52, and it will rise tomorrow at 7:47. The Moon is new today, and won’t be visible.
Let’s take our weekly look at the whereabouts of the naked-eye planets. By 8:30 PM or about a half hour or so after sunset, Venus may be seen very low in the West. Binoculars or a telescope will show a very tiny disc on Venus, because it is pretty much behind the Sun, a good way from us. However over the next 7 months it will be moving closer to us and becoming much larger. Jupiter is the brilliant star-like object more than halfway up in the southern sky at 9 PM. It’s the brightest object in the sky at that point. It has resumed its normal eastward motion, spending most of its evening appearance making up the ground it lost in its 4 months of retrograde motion. The planet and its moons are a treat for binoculars or a telescope.

Ephemeris: 03/11/2026 – Taking our weekly look at the whereabouts of the naked-eye planets
This is Ephemeris for Wednesday, March 11th. Today the Sun will be up for 11 hours and 41 minutes, setting at 7:43, and it will rise tomorrow at 8:00. The Moon, at last quarter today, will rise at 4:42 tomorrow morning.
Let’s take our weekly look at the whereabouts of the naked-eye planets. At 8:15 PM or about a half hour after sunset, Venus may be seen very low in the West. A very low western horizon will be necessary to spot it, like from the shore of Lake Michigan. Saturn is no longer visible, being too close to the direction of the Sun. Jupiter is the brilliant star-like object more than halfway up in the southern sky. It’s the brightest star-like object in the sky. The planet and its moons are a treat for binoculars or a telescope. Jupiter’s four brightest, so-called Galilean Moons are on the east side of the planet, though binoculars will probably show three. The moon closest to the planet are two moons close together, which are resolved in telescopes.

Ephemeris: 03/10/2026 – Finding Cancer the crab
This is Ephemeris for Tuesday, March 10th. Today the Sun will be up for 11 hours and 38 minutes, setting at 7:42, and it will rise tomorrow at 8:02. The Moon, 1 day before last quarter, will rise at 3:50 tomorrow morning.
The constellation of Cancer the crab is made of dim stars, which are generally connected, in constellation charts, with lines that make either the letter K or an upside down Y. It lies directly between the star pair Castor and Pollux in Gemini and Regulus in Leo. In the center of the constellation is, what to the naked-eye is a fuzzy spot called Praesepe, or the manger. The two nearby stars, one above left, and one below left are Asellus Borealis, and Asellus Australis, the northern and southern donkey colts feeding out of the manger. Viewing that fuzzy spot with a pair of binoculars will reveal that it’s not fuzzy at all. It resolves into a cluster of stars, which astronomers, over the years, have called the Beehive cluster.

Ephemeris: 03/09/2026 – The Great Underwater Panther in the stars
This is Ephemeris for Monday, March 9th. Today the Sun will be up for 11 hours and 35 minutes, setting at 7:41, and it will rise tomorrow at 8:04. The Moon, 2 days before last quarter, will rise at 2:50 tomorrow morning.
As Orion tilts into the southwest at 9 PM I’m reminded of our Anishinaabek native peoples here in Michigan, who saw it as the Winter Maker slowly beginning to leave the scene in the southwest. At this time in the southeast is Curly Tail, the Great Panther. I first knew him as the Great Underwater Panther, which tells us where he lives… beneath the ice. He’s in the sky to warn us that the warmer weather of spring is coming, and the ice on the lakes and rivers is getting thin. Be careful to not fall through and drown, becoming a victim of the Great Panther. The stars of the panther include those of the head of Leo the lion the great backwards question mark, as his curly tail, to his head, the head of what we call Hydra the water snake.

Ephemeris: 03/06/2026 – The Fisher announces the coming of the maple sugaring season
This is Ephemeris for Friday, March 6th. Today the Sun will be up for 11 hours and 25 minutes, setting at 6:37, and it will rise tomorrow at 7:09. The Moon, 3 days past full, will rise at 10:30 this evening.
March is a month of transitions. The stars of the winter skies, that is Orion and his merry band of bright stars, move to the west as those of spring rise in the east. The Big Dipper is ascending in the northeastern sky, after lying low in the north during the long dark evenings in the heart of winter. The dipper is the hind end of the Great Bear, officially Ursa Major. The Anishinaabe peoples of the Great Lakes region saw the Big Dipper as the hind end and tail of a magical creature called Fisher, or in their language Ojiig, who brought summer to the Earth. Its position in the sky around the pole announces the seasons. The Fisher’s ascension high into the northeastern sky signals the start of the maple sugaring season later this month.

Ephemeris: 03/04/2026 – Taking our weekly look at the whereabouts of the naked-eye planets
This is Ephemeris for Wednesday, March 4th. Today the Sun will be up for 11 hours and 19 minutes, setting at 6:34, and it will rise tomorrow at 7:13. The Moon, 1 day past full, will rise at 8:14 this evening.
Let’s take our weekly look at the whereabouts of the naked-eye planets. At 7 PM or about a half hour after sunset, Venus may be seen very low in the West. Above it and a bit to the left might be Saturn which may not show up until a quarter of an hour later. We are in the last third of winter and the sunset times are increasing rapidly and taking with it Saturn. The evening sky will shift dramatically this Sunday when Daylight Saving Time returns, giving us darker mornings and brighter evenings. Jupiter is the brilliant star-like object more than halfway up in the southern sky. It’s the brightest star-like object in the sky. The planet and its moons are a treat for binoculars or a telescope.

Ephemeris: 03/03/2026 – Eclipse prospects for the rest of the year
This is Ephemeris for Tuesday, March 3rd. Today the Sun will be up for 11 hours and 16 minutes, setting at 6:33, and it will rise tomorrow at 7:14. The Moon, at full today, will rise at 7:04 this evening.
If you’re listening to me right now the total lunar eclipse this morning has ended or will shortly end. In any case it’s invisible because, even if it’s ongoing, twilight has wiped it out. Then there is the possibility of clouds, which I can’t predict from when I’m recording this Sunday night. We do have another chance to view a lunar eclipse, this year, on the night of August 27-28th. It’ll be a little bit earlier. It will start late in the evening and be almost total after midnight. There’s also going to be a solar eclipse on August 12th, but it will be just a little nibble of the moon on the sun for us. It’s going to be total for the east coast of Greenland, the northern Atlantic, and northern Spain, before ending at sunset in the Mediterranean Sea.

Ephemeris: 03/02/2026 – There’s a total lunar eclipse tomorrow morning
This is Ephemeris for Monday, March 2nd. Today the Sun will be up for 11 hours and 13 minutes, setting at 6:32, and it will rise tomorrow at 7:16. The Moon, 1 day before full, will set at 7:19 tomorrow morning.
Early tomorrow morning* there will be total lunar eclipse. A lunar eclipse, also known as an eclipse of the Moon occurs when the full moon moves into the earth’s shadow cutting off most of its sunlight. A little sunlight does get in by being bent around the Earth by its atmosphere through all the sunrises and sunsets going on at that time. The moon’s color generally becomes dark red, this also depends on the Earth’s atmosphere and the amount of clouds, smoke and volcanic ash that are in it at the time. The partial phase will begin at 4:50 AM and will last until totality starts at 6:04 AM. Totality will last until 7:02 AM. The growing twilight may cause the totally eclipsed Moon to disappear before then.

* The Moon sets for us in Michigan before the end of the eclipse. Locations west of us in North America and the Pacific get to see the entire eclipse.

| 04:50 AM | Begin Partial phase. The umbra will encroach onto the Moon from upper left to lower right. The dull red of the umbral shadow may be discerned near the beginning of totality. |
| 05:40 AM | Astronomical Twilight begins. The Sun is 18° below the horizon. |
| 06:04 AM | Begin Totality. The expected dull red of the Moon will be brighter on the edge nearest the edge of the umbral shadow. How long will the totally eclipsed Moon be visible? |
| 06:14 AM | Nautical Twilight begins. The Sun is 12° below the horizon. |
| 06:34 AM | Mid-Eclipse |
| 07:03 AM | End Totality. Will a tiny slice of the Moon become visible in the brightening sky before it sets? |
