02/28/2020 – Ephemeris – Previewing March Skies

February 28, 2020 Comments off

Ephemeris for Friday, February 28th. Today the Sun will be up for 11 hours and 5 minutes, setting at 6:28, and it will rise tomorrow at 7:21. The Moon, 3 days before first quarter, will set at 11:30 this evening.

Let’s look at the skies for the month of March. The Sun will pass the celestial equator as the promising season of spring will begin. Daylight hours in the Interlochen/Traverse City area and will increase from 11 hours and 11 minutes Sunday to 12 hours 45 minutes on the 31st. The altitude, or angle, of the Sun above the southern horizon at local noon will be 38 degrees Sunday and will ascend to nearly 50 degrees on the 31st. Spring will start on the 19th at 11:50 p.m. Part of the fault for that early date is the switch to daylight saving time this early in the year a while back. The Gregorian calendar reform of 1582 will keep the vernal equinox from falling much further back. So spring will come a bit early this year, calendar-wise.

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

Tomorrow starts a new year and a new decade. The daylight hours start slowly getting longer and will accelerate during the month. Daylight hours will increase from 8 hours and 52 minutes tomorrow to 9 hours and 45 minutes on the 31st. The sunrise time will decrease from 8:20 tomorrow to 8:03 at months end. The sunset times will increase from 5:12 tomorrow to 5:49 on the 31st. Along with that the altitude of the sun at noon will increase from 22 degrees tomorrow to nearly 28 degrees at month’s end. It will be a degree lower for folks in the Straits area because they are a degree of latitude farther north. Local noon, by the way for Interlochen and Traverse City is about 12:51 p.m. in January.

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

December is the month with the shortest daylight hours. Winter will officially arrive at the winter solstice on the 21st at 11:19 p.m. There will be little movement in the sunset times: In the Traverse City/Interlochen area this will be from 5:03 Sunday, down to 5:02 and then advancing to 5:11 at the end of the month. There is more movement in the sunrise times which will advance from 7:59 Sunday to 8:20 on the 31st. There is also little movement of daylight hours. The noontime Sun will hang around 22 to 23 degrees above the southern horizon all month. The Geminid meteors on the 14th will have competition with the nearly full moon. And to change the subject, tonight the planet Saturn will appear just above the crescent Moon.

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

11/01/2019 – Ephemeris – Previewing November Skies and a GTAS meeting

November 1, 2019 Comments off

Ephemeris for Friday, November 1st. The Sun will rise at 8:20. It’ll be up for 10 hours and 11 minutes, setting at 6:31. The Moon, 3 days before first quarter, will set at 10:13 this evening.

Let’s take a look at November skies. The time change back to standard time will set us back an hour on sunrise and sunset times, so it’ll be brighter in the morning and darker in the evening this Sunday. Out east in New York, the Sun is already setting before 5 p.m. It will never set that early here. The Sun is up for 10 hours 11 minutes today and that will dwindle down to 9 hours and 5 minutes at month’s end. The Sun reaches 30 and a half angular degrees above the southern horizon at local apparent solar noon, which is 12:25 p.m. this month.

The big event this month will be the transit of the planet Mercury across the face of the Sun on the morning of November 11th.  Mercury is too small to be seen with eclipse glasses from left over from the eclipse of two years ago.  Project the Sun’s image using a telescope or binoculars on a white card.  Don’t look through the instruments or finders.  The event starts at sunrise at 7:35 and runs to 1:04 p.m.  I’ll have more on it next week.

Tonight there will be the monthly meeting of the Grand Traverse Astronomical Society at 8 p.m. followed by a star party at 9 p.m, if it’s clear at Northwestern Michigan College’s Rogers Observatory on Birmley Road.

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

10-01-2019 – Ephemeris – Previewing October skies

October 1, 2019 Comments off

Ephemeris for Tuesday, October 1st. Today the Sun will be up for 11 hours and 43 minutes, setting at 7:23, and it will rise tomorrow at 7:41. The Moon, 3 days past new, will set at 9:28 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 will drop from 11 hours and 43 minutes today to 10 hours 14 minutes on the 31st. The altitude of the Sun above the southern horizon at local noon will be 42 degrees today, and will descend to 31 degrees on Halloween, also in the Interlochen area. The Straits area will have the Sun a degree lower. Local noon, when the Sun is due south will be about 1:30 p.m. in Interlochen. The planets Saturn and Jupiter will appear low in the southwest in the early evening, and Venus just might be visible low in the west-southwest a half hour after sunset by month’s end.

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. 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, 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.
