05/14/2018 – Ephemeris – Big Dipper: Pointer to the Stars

May 14, 2018 Comments off

Ephemeris for Monday, May 14th. Today the Sun will be up for 14 hours and 47 minutes, setting at 9:03, and it will rise tomorrow at 6:14. The Moon, 1 day before new, will rise at 6:45 tomorrow morning.

The Big Dipper points to other stars and constellations. Right now the Big Dipper is nearly overhead. The front bowl stars point to Polaris, the North Star which never seems to move in the sky. The handle can be used to find two stars. First follow the arc of the handle away from the bowl to find the fourth brightest night-time star Arcturus in the base of the kite shaped constellation of Boötes. Straighten the arc to a spike and continue to the south and you will come to the bright blue-white star Spica in Virgo the virgin. You can remember these stars with the phrase “Follow the arc of the handle to Arcturus and then spike to Spica” or if you prefer the alternate pronunciation of the latter star “Speak to Speeka”.

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

Addendum

As can be seen below, there was one pointer function that didn’t make it into the program:  A leaky dipper drips on Leo.

Big Dipper Pointer to the Stars

Using the Big Dipper as a pointer to other stars. The pointers to Polaris could be life saving, since it is always north. The view is southward. The cross displayed near the center is the zenith. One might want to lay down to take all this in. Created using my LookingUp program.

02/13/2018 – Ephemeris – The Big Dipper as a pointer to other stars and constellations

March 13, 2018 Comments off

Ephemeris for Tuesday, March 13th. The Sun will rise at 7:58. It’ll be up for 11 hours and 47 minutes, setting at 7:46. The Moon, 4 days before new, will rise at 6:42 tomorrow morning.

With the Big Dipper up in the northeastern sky it is a sign that spring is coming. At 9 p.m. The Big Dipper can be used to find other stars and constellations. The Big Dipper’s most famous function is in locating Polaris the North Star. It’s a good way of finding directions at night. The altitude of Polaris, that is angle above the horizon, will give one’s approximate latitude north of the equator. Another constellation that can be found is Leo the lion. It is rising in the east in the evening, but it can also be found from the Big Dipper by imagining that a hole were drilled in the bottom of the bowl to let the water leak out. It would fall on Leo’s back. The Big Dipper can be used to find two more stars, but they have not yet risen.

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

The Big Dipper

The Big Dipper points to Polaris, the, North Star, and to Leo the lion at 9 p.m., March 13th. In another hour the 4th brightest night-time star Arcturus will appear above the eastern horizon pointed to by the arc of the handle of the Big Dipper. We’ll revisit the Big Dipper next month when Arcturus and Spica will also be found by the use of the Big Dipper. Created using Stellarium and Libre Office.

03/08/2018 – Ephemeris – Beware the Great Underwater Panther

March 8, 2018 Comments off

Ephemeris for Thursday, March 8th. The Sun will rise at 7:07. It’ll be up for 11 hours and 31 minutes, setting at 6:39. The Moon, 1 day before last quarter, will rise at 1:56 tomorrow morning.

The Anishinaabek people of the Great Lakes Region, which includes the Ottawa or Odawa, Chippewa and Ojibwe Indians have two constellations of winter that I know of. The first is The Winter Maker which uses many of Orion’s stars plus Aldebaran and Procyon. It rises in the eastern skies in the evening as winter is beginning. The second, of late winter and early spring is Curly Tail, the Great Underwater Panther. Which uses the stars of Leo the lion’s backward question mark as its tail and the small knot of stars that are the head of Hydra the water snake below Cancer as its head. I imagine this constellation was a warning to youngsters to keep off the thinning ice of spring, lest they fall in and be snatched by the great underwater panther that lives beneath the ice.

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

03/05/2018 – Ephemeris – Spring is coming: Leo is rising

March 5, 2018 Comments off

Ephemeris for Monday, March 5th. The Sun will rise at 7:13. It’ll be up for 11 hours and 22 minutes, setting at 6:35. The Moon, half way from full to last quarter, will rise at 10:53 this evening.

The constellation Leo the lion is now rising in the east at 9 pm. It’s below and left of the Big Dipper higher up in the east-northeast. Leo is marked by two sets of easily recognizable stars. The front of him is a backward question mark of stars, also known as the Sickle that mark his head and mane, along with the front part of his body. Regulus is the star at the bottom of that backwards question mark. It’s the Little King Star. The hind end of him is a triangle of stars ending with another bright star, but not as bright as Regulus. It’s Denebola which means Lion’s tail. It is thought when the Sun was in this constellation long ago that the lions were driven by the heat to quench their thirst in the Nile river. Ancients physicians thought medicines were poison when the Sun was here also.

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

Algieba is a binary star, which should be able to be split with any good telescope.  The magnitude 2.4 and 3.6 components are separated by 4.6 arc seconds.  Binary stars are one type of object that benefit from using high power to resolve.  The stars are very close in temperature, so each appears a yellow-orange color offering no color contrast.

05/25/2017 – Ephemeris – Another look at Leo the lion

Ephemeris for Ascension Thursday, Thursday, May 25th.  Today the Sun will be up for 15 hours and 9 minutes, setting at 9:14, and it will rise tomorrow at 6:04.  The Moon is new today, and won’t be visible.

The constellation Leo the lion is now high in the southwest at 10:30 pm.  It’s below the Big Dipper higher up near the zenith.  Leo is marked by two sets of easily recognizable stars.  The front of him is a backward question mark of stars, also known as the Sickle that mark his head and mane, along with the front part of his body.  Regulus is the star at the bottom of that backwards question mark.  It’s the Little King Star.  The hind end of him is a triangle of stars ending with another bright star, but not as bright as Regulus.  It’s Denebola which means Lion’s tail.  It was thought when the sun was in this constellation long ago that the lions were driven by the heat to quench their thirst in the Nile river.   Ancient physicians thought medicines were poison when the Sun was here too.

03/24/2017 – Ephemeris – Finding Leo

March 24, 2017 Comments off

Ephemeris for Friday, March 24th.  The Sun will rise at 7:37.  It’ll be up for 12 hours and 22 minutes, setting at 8:00.  The Moon, 3 days before new, will rise at 6:24 tomorrow morning.

At 10 p.m. the spring constellation of Leo the lion will be high in the east-southeast.  It can be found by locating the Big Dipper high in the northeast and imagining that a hole were drilled in the bowl to let the water leak out.  It would drip on the back of this giant cat.  The Lion is standing or lying facing westward.  His head and mane are seen in the stars as a backwards question mark.  This group of stars is also called the sickle.  The bright star Regulus is at the bottom, the dot at the bottom of the question mark.  A triangle of stars, to the left of Regulus, is the lion’s haunches.  Leo contains some nice galaxies visible in moderate sized telescopes.  The stars in Leo’s part of the sky are sparser than those in the winter sky.

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

03/23/2017 – Ephemeris – a single headed Hydra

March 23, 2017 Comments off

Ephemeris for Thursday, March 23rd.  The Sun will rise at 7:39.  It’ll be up for 12 hours and 19 minutes, setting at 7:59.  The Moon, 3 days past last quarter, will rise at 5:48 tomorrow morning.

In the southern evening sky can be found the constellation of Hydra the water snake.  Unlike the mythical monster Hercules fought of the same name this Hydra has but one head, which is its most distinctive part.  At 9 p.m. look to the south.  The head of Hydra is located directly to the left of Procyon the bright star in Orion’s little dog Canis Minor, and to the right of the star Regulus in Leo.  Hydra’s head is a small distinctive group of 6 stars that make a loop and the snake’s slightly drooping head.  At that time the sinuous body of Hydra sinks below the horizon in the southeast.  As it gets later in the evening the rest of Hydra’s body will slither to just above the southeastern horizon below the planet Jupiter this year and the bright star Spica in the constellation of Virgo.

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