Ephemeris: 06/10/2025 – Tonight’s Strawberry Moon
This is Ephemeris for Tuesday, June 10th. Today the Sun will be up for 15 hours and 30 minutes, setting at 9:27, and it will rise tomorrow at 5:56. The Moon, 1 day before full, will set at 5:36 tomorrow morning.
The actual instant that the Moon will be full, that is opposite the Sun in the sky, will be 3:44 tomorrow morning. So tonight’s full moon will be fuller than tomorrow night’s Moon. This month’s full moon is also called the Strawberry Moon by Native Americans, because this is the month that strawberries ripen. Also, the term honeymoon comes from the fact that many weddings are in June, when the full moon is low in the sky in the south and has a yellowish or honey color due to haze and atmospheric preferential scattering of blue light. The darker areas of the Moon give the effect of a face called the Man in the Moon. There is also a rabbit in the Moon, curled around the upper edge, with head and ears to the right and body to the left.
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; EDT, UT – 4 hours) unless stated otherwise. Times will be different for other locations.

05/31/2022 – Ephemeris – Let’s preview the sunny month of June
This is Ephemeris for Tuesday, May 31st. Today the Sun will be up for 15 hours and 19 minutes, setting at 9:20, and it will rise tomorrow at 6:00. The Moon, 1 day past new, will set at 10:56 this evening.
Let’s preview June skies. There will be a lot of sun in June and very little night. The daylight hours will increase a bit from 15 hours and 21 minutes Tomorrow to 15 hours and 34 minutes on the 21st, retreating back to 15 hours 31 minutes at month’s end. The altitude of the Sun above the southern horizon at local noon will hover around 68 to 69 degrees. Local noon, when the Sun is actually due south, will occur at about 1:43 p.m. Summer begins on the 21st at 5:14 am, when the Sun reaches its farthest north. The actual amount of nighttime will be quite short, mostly due to the length of daylight, but also because twilight lasts much longer than average because the Sun sets at a shallow angle. On the 21st, there’s theoretically only 3 ½ hours of total darkness if the Moon wasn’t up.
The astronomical event times given are for the Traverse City/Interlochen area of Michigan (EDT, UT – 4 hours). They may be different for your location.

June Evening Star Chart
The planets and stars are plotted for the 15th at 11 p.m. EDT in the evening and 4 a.m. for the morning chart. These are the chart times. Note that Interlochen/Traverse City is located approximately 45 minutes behind our time meridian, West 75° longitude. (An hour 45 minutes behind our daylight saving time meridian during EDT). To duplicate the star positions on a planisphere you may have to set it to 1 hour 45 minutes earlier than the current time.
Note the chart times of 11 p.m. and 4 a.m. are for the 15th. For each week before the 15th, add ½ hour (28 minutes if you’re picky). For each week after the 15th, subtract ½ hour, or 28 minutes. The planet positions are updated each Wednesday on this blog. For planet positions on dates other than the 15th, check the Wednesday planet posts on this blog for weekly positions.

06/01/2021 – Ephemeris – Previewing June Skies
This is Ephemeris for Tuesday, June 1st. Today the Sun will be up for 15 hours and 21 minutes, setting at 9:21, and it will rise tomorrow at 5:59. The Moon, 1 day before last quarter, will rise at 2:49 tomorrow morning.
This is the 46th anniversary of this program as we start our 47th orbit of the Sun. Let’s take a look at June skies. There will be a lot of Sunshine this month. The daylight hours will increase a bit from 15 hours and 21 minutes today to 15 hours and 34 minutes on the 21st, retreating back to 15 hours 31 minutes at month’s end. At this time of the year the sunset times for Ludington, Interlochen, Petoskey and Mackinaw City are very nearly the same. However, the sunrise times are at their most divergent. With Ludington’s sunrise being 14 minutes later than Mackinaw City’s. The altitude of the Sun above the southern horizon at local noon (1:44 pm in Interlochen) on the solstice, June 20th will be 68 and three-quarters degrees in Interlochen. Summer will start at 11:32 pm that night.
The big event this month will be a sunrise partial eclipse on the 10th. I’ll have more information next week.
The astronomical event times given are for the Traverse City/Interlochen area of Michigan. They may be different for your location.

05/31/2016 – Ephemeris – Previewing June’s bright skies
Ephemeris for Tuesday, May 31st. Today the Sun will be up for 15 hours and 20 minutes, setting at 9:20, and it will rise tomorrow at 6:00. The Moon, 2 days past last quarter, will rise at 3:55 tomorrow morning.
Tomorrow will be the first of June, so let’s preview June skies. There will be a lot of sunlight in June. The daylight hours will increase a bit from 15 hours and 21 minutes tomorrow to 15 hours and 34 minutes on the 20th, the solstice, retreating back to 15 hours 31 minutes at month’s end. At this time of the year the sunset times for Ludington, Interlochen, Petoskey and Mackinaw City are very nearly the same.* However the sunrise times are at their most divergent. With Ludington’s sunrise being 14 minutes later than Mackinaw City’s. The altitude of the sun above the southern horizon at local noon will increase from about 67 and a half degrees to 68 and three-quarters on the 20th. Local noon, when the sun is actually due south will occur at about 1:43 p.m.
Times are for the Traverse City/Interlochen area of Michigan. They may be different for your location.

June Star Chart

Star Chart for June 2016. Created using my LookingUp program. To enlarge in Firefox Right-click on image then click View image.
The planets and stars are plotted for the 15th at 11 p.m. EDT. That is chart time. Note, Traverse City is located approximately 45 minutes behind our time meridian. (An hour 45 minutes behind our daylight saving time meridian.) To duplicate the star positions on a planisphere you may have to set it to 1:45 earlier than the current time if you are near your time meridian.
Evening nautical twilight ends at 10:45 p.m. EDT on the 1st, increasing to 10:57 p.m. EDT on the 30th.
Morning nautical twilight starts at 4:36 a.m. EDT on the 1st, and decreasing to 4:35 a.m. EDT on the 30th.
Add a half hour to the chart time every week before the 15th and subtract a half hour for every week after the 15th. Before the 13th also subtract an hour for Standard Time.
For a list of constellation names to go with the abbreviations click here.
- Pointer stars at the front of the bowl of the Big Dipper point to Polaris the North Star
- A leaky Big Dipper drips on Leo
- Follow the arc of the handle of the Big Dipper to the star Arcturus
- Extend the arc to a spike to point to Spica.
- The Summer Triangle is outlined in red. Vega in Lyra (Lyr), Deneb in Cygnus (Cyg) and Altair in Aquila (Aql).

06/01/2015 – Ephemeris – Starting orbit 41 looking at June skies
Ephemeris for Monday, June 1st. Today the Sun will be up for 15 hours and 20 minutes, setting at 9:21. The Moon, 1 day before full, will set at 6:17 tomorrow morning and tomorrow the Sun will rise at 6:00.
We’ll start Ephemeris’ 41st orbit of the Sun by looking at the skies of June. There’ will be a lot of sun in June and very little night. The daylight hours will increase a bit from 15 hours and 20 minutes today to 15 hours and 34 minutes on the 21st, retreating back to 15 hours 31 minutes at month’s end. At this time of the year the sunset times for Ludington, Interlochen, Petoskey and Mackinaw City are very nearly the same. However the sunrise times are at their most divergent. With Ludington’s sunrise being 14 minutes later than Mackinaw City’s. The altitude of the sun above the southern horizon at local noon will hover around 68 to 69 degrees. Local noon, when the sun is actually due south will occur at about 1:43 p.m. Here’s what we’ve been waiting for: Summer will start on the 21st at 12:38 p.m.
