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.

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

10/11/2018 – Ephemeris – Pegasus the aerobatic horse

October 11, 2018 Comments off

Ephemeris for International Day of the Girl, Thursday, October 11th. The Sun will rise at 7:53. It’ll be up for 11 hours and 11 minutes, setting at 7:05. The Moon, 3 days past new, will set at 8:56 this evening.

Rising ever higher in the east at as it gets dark around 9 p.m. can be found one of the great autumn constellations: Pegasus the flying horse of Greek myth. Its most visible feature is a large square of four stars, now standing on one corner. This feature, called the Great Square of Pegasus, represents the front part of the horse’s body. The horse is quite aerobatic because it is seen flying upside down. Remembering that fact, the neck and head is a bent line of stars extending from the right corner star of the square. Its front legs can be seen in a gallop extending to the upper right from the top star of the square. From the left star extend, not hind legs but the constellation of Andromeda, an important constellation in its own right.  The Anishinaabek peoples native to this region saw ab upright Moose (Mooz) here.

11/21/2017 – Ephemeris – The constellation of the fish has me looking for the fish

November 21, 2017 1 comment

Ephemeris for Tuesday, November 21st. The Sun will rise at 7:47. It’ll be up for 9 hours and 21 minutes, setting at 5:09. The Moon, 3 days past new, will set at 7:50 this evening.

High in the south at 8 or 9 p.m. are the four bright stars of the Great Square of Pegasus, the upside down flying horse. Lying along the left and bottom sides of that square is the constellation of Pisces the fish, one of the 12 constellations of the Zodiac that lie along the path of the sun, moon and planets. Even though the constellation is called the fish, the two fish themselves are not represented in the stars, at least that’s how I see it. What can be traced in the stars is the rope, that’s tied to their tails, anchored at the extreme southeastern part of the constellation. The right or western end of the Pisces is the asterism, or informal constellation, of the Circlet. It’s the loop of 5 stars, the rope around the tail of one of the two fish. The other end, without a loop, ends up under Andromeda.  Artists have always supplied the fish.

11/07/2017 – Ephemeris – The autumn constellations are all visible in the early evening

November 7, 2017 1 comment

Ephemeris for Election Day for some folks, Tuesday, 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, 3 days before last quarter, will rise at 8:49 this evening.

We’ll have about an hour and a half of reasonably dark skies between 6:30 and nearly 9 p.m. – At 8 p.m. all the autumn constellations are visible. The Zodiacal constellations from Capricornus in the southwest through Aquarius, Pisces and Aries, all relatively faint to Taurus rising in the east northeast. Pegasus the flying horse is seen in the high south-southeast. It and the connected constellation of Andromeda the chained princess are seen above Aquarius through Aries. The bright star Fomalhaut holds a lonely vigil low in the south, High in the northeast is the W shaped constellation of Cassiopeia the queen, under which is Perseus, her son-in-law and hero down to the bright star Capella.

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

10/16/2017 – Ephemeris – Andromeda, the chained princess

October 16, 2017 1 comment

Ephemeris for Monday, October 16th. The Sun will rise at 7:59. It’ll be up for 10 hours and 56 minutes, setting at 6:55. The Moon, 3 days before new, will rise at 5:29 tomorrow morning.

The stars of the constellations Andromeda the chained princess look like they’re supposed to be the hind legs of Pegasus the flying horse which is high in the southeast at 9 p.m. Andromeda is high in the east She is seen in the sky as two diverging curved strings of stars that curve to the left and up from the leftmost star of the Great Square of Pegasus. Her predicament was caused by her boastful mother Cassiopeia, and the wrath of the god Poseidon. She was rescued by the hero Perseus, a nearby constellation, riding his steed Pegasus. Andromeda’s claim to astronomical fame is the large galaxy barely visible to the unaided eye just above the upper line of stars, the Great Andromeda Galaxy 2.5 million light years away.

10/12/2017 – Ephemeris – Is it a flying horse or a moose?

October 12, 2017 1 comment

Ephemeris for Thursday, October 12th. The Sun will rise at 7:54. It’ll be up for 11 hours and 8 minutes, setting at 7:02. The Moon, at last quarter today, will rise at 1:02 tomorrow morning.

A reminder that fall is here is located high in the southeast around 9 p.m. It’s one of the great autumn constellations: Pegasus the flying horse of Greek myth. Its most visible feature is a large square of four stars, now standing on one corner. This feature, called the Great Square of Pegasus, represents the front part of the horse’s body. The horse is quite aerobatic, because it is seen flying upside down. Remembering that fact, the neck and head is a bent line of stars emanating from the right corner star of the square. Its front legs can be seen in a gallop extending to the upper right from the top star of the square. To the Anishinaabek peoples in the Great Lakes region it is the Moose, body where the square is and head where the front legs of Pegasus are.  It’s antlers use the stars of Lacerta the lizard.

I don’t care what the artists think, I still think the circlet is a loop around the western fish’s tail.
