11/14/2018 – Ephemeris – The bright planets this week

November 13, 2018 Comments off

Ephemeris for Wednesday, November 14th. The Sun will rise at 7:38. It’ll be up for 9 hours and 37 minutes, setting at 5:15. The Moon, 1 day before first quarter, will set at 11:18 this evening.

Let’s look at the bright planets for tonight. Two of them are visible in the evening sky. Jupiter will set too soon after sunset to be seen. It will set only 29 minutes after the Sun. Saturn, the ringed planet, will start the evening low in the southwestern sky and will set at 7:59 p.m. Mars will be low in the south as the skies darken tonight. Mars will be due south at 7:15 p.m., and it will set at 12:24 a.m. Mars is moving eastward, crossing the constellation of Aquarius this month. It’s currently at the western edge of Aquarius, moving eastward and northward, so its setting time won’t change much over this month. Venus, our brilliant morning star, will rise at 5:15 a.m. in the east southeast. The blue-white star Spica is just above and right of it now.

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

11/13/2018 – Ephemeris – The Summer Triangle in autumn

November 13, 2018 Comments off

Ephemeris for Tuesday, November 13th. The Sun will rise at 7:37. It’ll be up for 9 hours and 39 minutes, setting at 5:16. The Moon, 2 days before first quarter, will set at 10:20 this evening.

The Summer Triangle is still in the sky at 9 p.m., even though it’s November. These three bright stars that straddle the Milky Way are high in the east for most of the summer, move overhead and begin to slide to the west in autumn. We will lose Altair, the southernmost of the three stars at 9 p.m. on the winter solstice, December 21st. We’ll lose the brightest, Vega in January. For the northern half of the IPR listening area the northernmost of the triangle stars, Deneb won’t quite set below a north Lake Michigan horizon. Next spring we’ll be waiting and watching for these three stars to rise, reclaim the skies, and bring again the warm summer skies. The winter skies do however have more bright stars than the summer sky.

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

11/12/2018 – Ephemeris – Orion is rising

November 12, 2018 Comments off

Ephemeris for Veterans Day Observed, Monday, November 12th. The Sun will rise at 7:35. It’ll be up for 9 hours and 41 minutes, setting at 5:17. The Moon, 3 days before first quarter, will set at 9:25 this evening.

Just after the Moon sets tonight winter’s most dazzling constellation will be rising, Orion the hunter of Greek myth. The stars of his torso are in a rectangle leaning to the left. Orion’s belt of three stars in a straight line in the center of the rectangle is nearly vertical. The Anishinaabe peoples whose region we live in see the constellation of the Wintermaker rather than Orion. It uses Orion’s torso and belt stars, but his arms are spread wide from Aldebaran in the face of Taurus the bull to the west to Procyon in Canis Minor, which won’t rise until 11 p.m. to the east. The Wintermaker’s arms are wide enough to embrace the entire winter sky. Its name in Anishinaabemowin, which is Biboonikeonini, means “North Wind”.

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

Orion or Wintermaker rising
Take your pick: it’s either Orion rising of the Wintermaker rising at 9:30 p.m. November 12th. Created using Stellarium and GIMP, and Western and Ojibwe star lore.

11/09/2018 – Ephemeris – The Great Andromeda Galaxy

November 9, 2018 Comments off

Ephemeris for Friday, November 9th. The Sun will rise at 7:31. It’ll be up for 9 hours and 49 minutes, setting at 5:21. The Moon, 2 days past new, will set at 7:03 this evening.

In the south at 9, this evening can be found a large square of stars, the Great Square of Pegasus the flying horse, flying upside down to the right. What looks like its hind legs stretching to the left from the upper left corner star is another constellation, Andromeda the chained princess. She is seen in the sky as two diverging curved strings of stars that curve upward. She was rescued by the hero Perseus, a nearby constellation, riding Pegasus. Andromeda’s claim to astronomical fame is the large galaxy seen with the unaided eye just above the upper line of stars. The Great Andromeda Galaxy is 2.5 million light years away. To the naked eye the galaxy appears as a small smudge of light. In binoculars the galaxy is a delicate spindle of light.

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

11/08/2018 – Ephemeris – More constellations of autumn: Andromeda, Triangulum and Aries

November 8, 2018 Comments off

Ephemeris for Thursday, November 8th. The Sun will rise at 7:30. It’ll be up for 9 hours and 51 minutes, setting at 5:22. The Moon, 1 day past new, will set at 6:26 this evening.

High in the south at 9 p.m. can be seen the Great Square of Pegasus. From the top left star of the square diverge two curved lines of stars that is Andromeda the chained princess. Just below and left of Andromeda is a slender triangle of stars, none particularly bright. It has a name you can easily see in the stars, Triangulum, the triangle. Early Christians saw it as the Mitre of Saint Peter or the Trinity. Another small constellation seen below Triangulum is the much better known constellation Aries the ram, a small hockey stick of a constellation, not that hard to spot. It is the first constellation of the Zodiac, where the Sun is supposed to enter on the first day of spring. Due to the wobble of the Earth’s axis over the millenia, that honor is now given to Pisces.

11/07/2018 – Ephemeris – Two Two evening planets and a morning planet visible now

November 7, 2018 Comments off

Ephemeris for Wednesday, November 7th. The Sun will rise at 7:28. It’ll be up for 9 hours and 54 minutes, setting at 5:23. The Moon is new today, and won’t be visible.

Let’s look at the bright planets for tonight. Two of them are visible in the evening sky. Jupiter will set too soon after sunset to be seen. It will set only 44 minutes after the Sun. Saturn, the ringed planet, will start the evening low in the southwestern sky and will set at 8:24 p.m. Mars will be low in the south as the skies darken tonight. and is now 77.8 million miles (125.2 million km) away. Mars will be due south at 7:26 p.m., and it will set at 12:28 a.m. Mars is moving eastward, crossing the constellation of Aquarius this month. It’s currently at the western edge of Aquarius. Venus, now the brilliant morning star, will rise at 5:57 in the east southeast. It will grace our morning skies through next spring.

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

11/06/2018 – Ephemeris – The Taurid meteor showers

November 6, 2018 Comments off

Ephemeris for Election Day, Tuesday, November 6th. The Sun will rise at 7:27. It’ll be up for 9 hours and 57 minutes, setting at 5:24. The Moon, 1 day before new, will rise at 7:09 tomorrow morning.

We are in the midst of two showers of meteors that seen to come from the constellation of Taurus the bull. These are the Southern and Northern Taurids respectively. They only produce a handful of meteors per hour, but there seems to be some discrepancy in their peak dates. The International Meteor Organization has the Southern group peak October 10th. Other sources have it peak November 5th. The Northern group peaks on the 10th or 12th of November depending on the source. Anyway these are bits shed by Comet 2P/Encke, which has only a 3 year orbit of the Sun. Encke’s orbit also comes close to the Earth’s orbit where the Earth is at the end of June. I’ve always wondered if it was a piece of Encke’s nucleus that hit Siberia on June 30, 1908?

11/05/2018 – Ephemeris – Cassiopeia the Queen

November 5, 2018 Comments off

Ephemeris for Monday, November 5th. The Sun will rise at 7:26. It’ll be up for 9 hours and 59 minutes, setting at 5:26. The Moon, 2 days before new, will rise at 6:00 tomorrow morning.

The stars of the autumn skies are replacing the summer stars from the east. Look in the northeastern sky by 7 p.m. and you can find the W shaped constellation of Cassiopeia the queen. Cassiopeia is so far north that it never sets for us in Michigan. It is opposite the pole star Polaris from the Big Dipper. There’s a dim star that appears above the middle star of the W which turns it into a very crooked backed chair, Cassiopeia’s throne. Above and left of Cassiopeia is a dim upside down church steeple shaped constellation of Cepheus the king, her husband. The Milky Way flows through Cassiopeia toward the northeastern horizon and through the constellation of Perseus the hero, which kind of looks, to me anyway, like the cartoon roadrunner.

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

11/04/2018 – Ephemeris Extra – Wintermaker rising

November 4, 2018 Comments off

A chill is in the air, The Fisher, Ojiig’s bloody tail has swooped low in the north at midnight to paint the trees with their fall colors, and the leaves have fallen to the ground. Haven’t heard of the Fisher? I mention it from time to time here on my Ephemeris program on Interlochen Public Radio. It’s a constellation of the Anishinaabe peoples indigenous to this area of Michigan, of which the Chippewa, Ottawa, and Ojibwe are a part.

The Fisher occupies the stars which we know as the Big Dipper and the Great Bear, Ursa Major. And unlike the bear, a fisher really does have a long tail. The fisher is a real weasel-like animal whose diet apparently does not include fish. It is found across southern Canada and in the American West. I’ve related the story of the Fisher, and how he brought summer to the Earth, in these pages in the August 2012 issue and on my blog bobmoler.wordpress.com. Search for fisher. Like most legends, there are different versions of that story and others about the Fisher.
Fisher or not, summer is gone and the world seems darker and colder. Over in the east these evenings great winter constellation of Orion is rising. It brings to mind the Robert Frost poem Star-Splitter, and our star chart this month from the November 1st post:

“You know Orion always comes up sideways.
Throwing a leg up over our fence of mountains,
And rising on his hands, he looks in on me
Busy outdoors by lantern-light with something
I should have done by daylight, and indeed,
After the ground is frozen, I should have done
Before it froze, and a gust flings a handful
Of waste leaves at my smoky lantern chimney
To make fun of my way of doing things,
Or else fun of Orion's having caught me.
Has a man, I should like to ask, no rights
These forces are obliged to pay respect to?"

The rest of the poem is available on the Poetry Foundation website: https://www.poetryfoundation.org/poems/44273/the-star-splitter. The poem is about one Brad McLaughlin and his telescope. While I don’t approve of how he financed his telescope, I do share his enthusiasm.

The Wintermaker, Biboonikeonini’s, name literally means North Wind. While his torso is the same as Orion’s his arms stretch from Aldebaran in Taurus to Procyon in Canis Minor, just about spanning the entire winter sky. The pictographs, seen above of the Wintermaker, Curly Tail and Moose can only be seen from a canoe in the cliff face on one side of the narrows between North Hegman and Trease lakes, 15 miles north of Ely, Minnesota

 

Wintermaker rising
The Wintermaker (Orion) rising in the east-southeast. And Hole-In-The-Sky (Pleiades) as seen in Stellarium with Ojibwe Star Lore in Stellarium. From the Ojibwe Sky Star Map Constellation Guide, ISBN 978-0-615-98678-4 by A. Lee, W. Wilson, and C. Gawboy.

In late winter as Ojiig is rising in the northeast signaling the maple sugaring season, the Wintermaker is moving lower in the southwest. Some Ojibwe parents make bows for their children to shoot arrows at the Wintermaker to convince him to flee the skies so spring can begin as a way to teach them the old legends of their culture.

The Pleiades is an important group of stars for the Anishinaabe in several ways. It is the Hole-In-The-Sky, Bagone’giizhig, through which the Sky Woman fell and to give birth to the first humans on the Earth.

The Pleiades also represent the seven poles of the Shaking Tent Ceremony, and the seven sacred stones that are heated for the sweat lodge, which is also seen in the stars in the spring as Corona Borealis.

 

They are also the Seven Daughters of the Moon and Sun. They loved to dance and play, and when their father, the Moon was low in the sky, would descend to the Earth in a basket to do their thing. On one of their trips to the earth, one of them was captured by a human and she ended up falling in love with him, and married him. When father Moon found out he permanently dimmed her star, so now most people now only can spot 6 of the stars. This last bit seems to parallel the Greek story of the lost Pleiad.

11/02/2018 – Ephemeris – Back to basics tonight at the GTAS meeting

November 2, 2018 Comments off

Ephemeris for Friday, November 2nd. The Sun will rise at 8:22. It’ll be up for 10 hours and 7 minutes, setting at 6:30. The Moon, 2 days past last quarter, will rise at 3:27 tomorrow morning.

Tonight at this month’s meeting of the Grand Traverse Astronomical Society at 8 p.m. at Northwestern Michigan College’s Rogers observatory we will get back to basics for anyone wondering about the skies visible from one’s backyard. Learn the constellations by building your own star finder that shows where the stars are any night of the year. We’ll also show you how to use it. We will let you experiment with moon-balls, that will show the light and shadow of the Moon’s phases. Afterward, if it’s clear you’ll have a chance to use those star finders during the observation period starting around 9 p.m. The observatory is south of Traverse City, on Birmley Road, between Garfield and Keystone roads.

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