Ephemeris: 03/04/2026 – Taking our weekly look at the whereabouts of the naked-eye planets

March 4, 2026 Comments off

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.

The astronomical event times given in this blog are for the Traverse City/Interlochen area of Michigan (Lat 44.7° N, Long 85.7° W; EST, UT – 5 hours) unless stated otherwise. Times will be different for other locations.

Saturn and Venus in the west-southwestern sky at 7:15 PM tonight March 3, 2026, or 41 minutes after sunset. Spotting Mercury and Venus will be problematic: being too low in Venus’ case, and too faint in Saturn’s. The brightnesses of the planets are exagerated. Created using Stellarium.

Also shown is its track from last July to next July, and the retrograde loop that it is currently making, slowly moving to the West which it will do for the next 6 days until it stops (becomes stationary) on March 10th. Then it will resume its eastward motion. The inset shows a magnified view of the west end of the retrograde loop. Created using Stellarium, LibreOffice Draw and GIMP.

A low precision ephemeris of the Sun, Moon and naked eye planet positions for today and tomorrow
This is a low precision ephemeris of the Sun, Moon and naked eye planet positions for today and tomorrow, March 4th and 5th, 2026. Some of the columns are self-explanatory, others are not. The transit column is the time that the body crosses the meridian and is due south. Elong, for elongation, is the angle between the Sun and that body. RA is right ascension, which is the object’s east-west position on the celestial sphere in hours and minutes. Dec is declination which is the north-south position of the object on the celestial sphere in degrees and minutes. R is the distance of that object from the Sun in astronomical units. An astronomical unit is about 93 million miles or 150 million kilometers. And Delta is the distance of that object from the Earth, also in astronomical units. I omit the ‘m’ in am and pm for compactness. The data was generated using my LookingUp for DOS app and displayed as a table by my Ephemeris Helper app.

Ephemeris: 03/03/2026 – Eclipse prospects for the rest of the year

March 3, 2026 Comments off

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.

The astronomical event times given in this blog are for the Traverse City/Interlochen area of Michigan (Lat 44.7° N, Long 85.7° W; EST, UT – 5 hours) unless stated otherwise. Times will be different for other locations.

Maximums of the two eclipses visible from the Grand Traverse area in August 2026,
The maximums of the two eclipses visible from the Grand Traverse area in August of 2026. The solar eclipse of August 12th only lasts a little more than an hour, and at maximum the Moon encroaches only 11% into the Sun’s diameter. The August 28th partial lunar eclipse is more substantial. It will last three in the third hours and the Moon will immerse 93% of its diameter into the Earth’s inner shadow called the umbra, where the only sunlight to reach it filters through the Earth’s atmosphere from all the sunrises and sunsets around the world at the time.

Ephemeris: 03/02/2026 – There’s a total lunar eclipse tomorrow morning

March 2, 2026 Comments off

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 astronomical event times given in this blog are for the Traverse City/Interlochen area of Michigan (Lat 44.7° N, Long 85.7° W; EST, UT – 5 hours) unless stated otherwise. Times will be different for other locations.

* 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.

Addendum

Three views of the total lunar eclipse of March 3, 2026.
Three views of the total lunar eclipse of March 3, 2026. From left to right: Just after the beginning of the partial phase, when the Moon begina to enter the Earth’s umbra. Center is a few minutes before totality, when the Moon is almost completely imersed into the Earth’s umbra. On the right, the Moon at mid eclipse, with the brightening twilit sky. This is Stellarium’s rendition. I’m willing to bet that the Moon will actually be invisible at this point.
Total Lunar Eclipse March 3, 2026
Events for the Grand Traverse area (Eastern Standard Time)
Time Event
03:44 AM Begin Penumbral phase. This is the theoretical start of the eclipse. Nothing will appear to happen until about half an hour before the partial phase starts. Then the upper left part of the Moon will appear to darken.
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?
07:18 AM Sunrise
07:19 AM Moonset
