Ephemeris for New Years Day, Tuesday, January 1st. The Sun will rise at 8:20. It’ll be up for 8 hours and 52 minutes, setting at 5:12. The Moon, 3 days past last quarter, will rise at 4:59 tomorrow morning. | Happy New Year. Let’s preview the month of January. We’re a day from the latest sunrise at about the same time as today, 8:20 a.m. and will back down to 8:03 by the 31st. Sunset times are currently increasing by a minute a day from 5:12 p.m. today to 5:49 at month’s end. Listeners will have about the same sunrise time in Ludington, Interlochen/Traverse City, Petoskey and Mackinaw City, but the sunset times will vary markedly with the sunset times earlier in the north than the south. The Quadrantid meteor shower will reach peak on the 3rd in the evening. Also on the 3rd the Earth will be its closest to the Sun for the entire year. And on the 20th there will be a total lunar eclipse in the evening.

11/30/2018 – Ephemeris – Previewing December skies

Bob Moler with Ephemeris for Friday, November 30th. The Sun will rise at 7:58. It’ll be up for 9 hours and 5 minutes, setting at 5:04. The Moon, 1 day past last quarter, will rise at 1:29 tomorrow morning.

Let’s preview December’s skies. Winter will officially arrive on the 21st at 5:22 p.m., the winter solstice. The noontime sun will dip from 23 ½ degrees to a bit less than 22 degrees above the southern horizon on that day. There will be little movement in the sunset times: In the Traverse City/Interlochen area this will be from 5:03 tomorrow, down to 5:02 and then advancing to 5:11 at the end of the month. The sunrise times will advance from 7:58 tomorrow to 8:20 on the 31st. The big event in December will be the Geminid meteor shower whose maximum is on the morning of the 14th. An old comet will make a close pass of the Earth and may be quite bright by mid-month. Watch for Comet Wirtanen.

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

The planets and stars are plotted for the 15th at 9 p.m. EST in the evening and 6 a.m. for the morning chart. These are the chart times. Note that Traverse City is located approximately 45 minutes behind our time meridian. (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 9 p.m. and 6 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.

11/01/2018 – Ephemeris – November preview

Ephemeris for Thursday, November 1st. The Sun will rise at 8:20. It’ll be up for 10 hours and 10 minutes, setting at 6:31. The Moon, 1 day past last quarter, will rise at 2:14 tomorrow morning.

Let’s look ahead at the skies for the month of November. The Sun is still moving south rapidly. Daylight hours in the Interlochen/Traverse City area and will drop from 10 hours and 10 minutes today to 9 hours 5 minutes on the 30th. The altitude, or angle, of the Sun above the southern horizon at local noon will be at 30 degrees today and will descend to 23 and a half degrees on the 30th. The altitude of the Sun in the Straits area will be a degree lower. Local noon, this month, will be about 12:30 p.m. once we’re on standard time. The Leonid meteor shower will reach multiple peaks from the 16th through the 21st and is expected to be lackluster and may only produce 10 to 15 meteors per hour. But the Leonids can be surprising.

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

10/01/2018 – Ephemeris – Previewing October skies

Ephemeris for Monday, October 1st. The Sun will rise at 7:40. It’ll be up for 11 hours and 42 minutes, setting at 7:23. The Moon, 1 day before last quarter, will rise at 11:55 this evening.

Let’s look at the skies for the month of October. The Sun will still be moving south rapidly. Daylight hours in the Interlochen/Traverse City area and will drop from 11 hours and 42 minutes today to 10 hours, 13 minutes at months end. The altitude of the sun above the southern horizon at local noon will be 42 degrees today in the Interlochen area and will descend to 31 degrees on Halloween. Venus will pass the Sun, moving from the evening sky to the morning sky on the 26th. Venus has not been too noticeable in the evening for the last month, but in early November it will seem to suddenly appear in the morning sky. It can be mistaken as a UFO, especially with its tiny Cheshire Cat crescent smile in binoculars or a small telescope.

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

Addendum

October Evening Star Chart

Star Chart for October 2018 (10 p.m. EDT October 15, 2018). Created using my LookingUp program. Click on image to enlarge.

The planets and stars are plotted for the 15th at 9 p.m. EDT in the evening and 6 a.m. for the morning chart. These are the chart times. Note that Traverse City is located approximately 45 minutes behind our time meridian. (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 9 p.m. and 6 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. 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.

• The Summer Triangle is in red.
• DracR on the evening star chart is the radiant for the Draconid meteor shwer which peaks on the 10th.
• OriR on the morning star chart is the radiant of the Orionid meteor shower which peaks on the 21st.

07/31/2018 – Ephemeris – Previewing August skies

Ephemeris for Tuesday, July 31st. The Sun rises at 6:27. It’ll be up for 14 hours and 41 minutes, setting at 9:09. The Moon, half way from full to last quarter, will rise at 11:17 this evening.

Let’s look ahead at the month of August in the skies. Daylight hours will decrease from 14 hours and 39 minutes tomorrow to 13 hours 17 minutes on the 31st. The altitude of the sun at local noon, that is degrees of angle above the horizon will decrease from 63 degrees tomorrow to just over 53 degrees on the 31st. Straits area listeners can subtract one more degree from those angles. Local noon, when the Sun is due south, is about 1:43 p.m. The Perseid meteor shower will reach its peak all night on the 12th. It will be a dark night with the one day old moon setting at 10 p.m. The radiant point, where the meteors will seem to come from, will be rising higher in the northeastern sky all night. On the 17th Venus will reach ts greatest separation from the Sun in the evening sky.

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

The planets and stars are plotted for the 15th at 10 p.m. EDT in the evening and 4:30 a.m. for the morning chart. These are the chart times. Note that Traverse City is located approximately 45 minutes behind our time meridian. (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 10 p.m. and 4:30 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. 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.

06/29/2018 – Ephemeris – Previewing July skies

Ephemeris for Friday, June 29th. Today the Sun will be up for 15 hours and 32 minutes, setting at 9:32, and it will rise tomorrow at 6:00. The Moon, 1 day past full, will rise at 10:38 this evening.

Lets preview July’s skies. The Sun, having reached its northern solstice, is beginning to slide southward again, at first imperceptibly, then with greater speed. The daylight hours will decrease from 15 hours and 30 minutes Sunday to 14 hours 41 minutes at month’s end. The daylight hours will be slightly shorter south of Interlochen, and slightly longer to the north. The altitude of the Sun at local noon, when the Sun is due south will decrease from 68 degrees today to 63 degrees at month’s end. The Sun will be a degree lower in the Straits area. Despite the warmth, the Earth will reach its greatest distance from the Sun on Friday the 6th. The planets visible this month in the evening are Venus, Jupiter, Saturn and later, Mars.

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