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.

11/21/2016 – Ephemeris – The two fishies of Pisces

November 21, 2016 Comments off

Ephemeris for Monday, November 21st.  The Sun will rise at 7:48.  It’ll be up for 9 hours and 20 minutes, setting at 5:08.  The Moon, at last quarter today, will rise at 12:54 tomorrow morning.

High in the south-southeast at 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 the great 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 fish themselves are not represented in the stars.  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 that is seen in the stars.  The right or western end of 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.

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

09/27/2016 – Ephemeris – The princess Pegasus helped save

September 27, 2016 Comments off

Ephemeris for Tuesday, September 27th.  The Sun will rise at 7:36.  It’ll be up for 11 hours and 53 minutes, setting at 7:29.  The Moon, 3 days before new, will rise at 5:08 tomorrow morning.

In the east at 9 this evening can be found a large square of stars standing on one corner, the Great Square of Pegasus the flying horse.  What look like its hind legs stretching to the left from the left corner star is another constellation, Andromeda the chained princess.  She is seen in the sky as two diverging upward curving strings of three stars each.  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, 2.5 million light years away.  To the unaided eye the galaxy appears as a small smudge of light.  In binoculars the galaxy is a delicate spindle of light.

I added some constellation lines to Andromeda since yesterday to match the transcript and how I see her.  Looks like I have some work to do with Perseus, before I talk about him later on.  He doesn’t look like a chicken enough.  I’m going for laughs here.

Ephemeris for Monday, September 26th.  The Sun will rise at 7:35.  It’ll be up for 11 hours and 56 minutes, setting at 7:31.  The Moon, 3 days past last quarter, will rise at 4:05 tomorrow morning.

Rising and almost half way up the sky 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 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.  From the left star extend, not hind legs but the constellation of Andromeda, rescued with the help of Pegasus.

09/08/2015 – Ephemeris – Pegasus flies again

September 8, 2015 Comments off

Ephemeris for Tuesday, September 8th.  The Sun will rise at 7:13.  It’ll be up for 12 hours and 53 minutes, setting at 8:07.   The Moon, 3 days past last quarter, will rise at 3:44 tomorrow morning.

As summer wanes and the Sagittarius teapot tips its contents on the southwestern horizon the constellations of autumn rise in the east.  I’ve already mentioned Cassiopeia, which is so far north it never really leaves us in northern Michigan.  Pegasus the flying horse of Greek mythology is perhaps the most famous of the autumn constellations, and easiest to find.  Its body, a large square of four stars, is in the east, standing on one corner.  It is known as the Great Square of Pegasus.  Only the front half of the horse is in the sky, and he’s flying upside down with his neck and head extending to the right from the rightmost star.  His galloping front legs extend upward from the top star.  Our Anishinaabek native peoples saw a moose here standing upright.
