06/19/2020 – Ephemeris – Summer arrives tomorrow with an eclipse of the Sun the next day

June 19, 2020 Comments off

This is Ephemeris for Friday, June 19th. Today the Sun will be up for 15 hours and 34 minutes, setting at 9:31, and it will rise tomorrow at 5:57. The Moon, 2 days before new, will rise at 5:25 tomorrow morning.

Tomorrow afternoon at 5:43 pm summer will begin, as the Sun reaches its greatest northerly excursion, right over the tropic of Cancer, 23 ½ degrees north latitude on the Earth’s surface. It’s called the summer solstice for those of us north of the equator. Early Sunday morning there will be an annular eclipse of the Sun. We won’t see it in the United States, however it will be visible for parts of Africa and southern Asia. The Moon will be too far away to completely cover the face of the Sun leaving a ring or annulus at maximum eclipse, a so-called Ring of Fire. It is the second of a triad of eclipses this eclipse season. Two weeks ago there was a slight eclipse of the Moon and two weeks from now another slight eclipse of the Moon to finish the season.

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

06/05/2020 – Ephemeris – A penumbral eclipse of the Moon for the eastern hemisphere of Earth today

June 5, 2020 Comments off

This is Ephemeris for Friday, June 5th. Today the Sun will be up for 15 hours and 26 minutes, setting at 9:24, and it will rise tomorrow at 5:57. The Moon, at full today, will rise at 9:32 this evening.

There will be a penumbral eclipse of the Moon this afternoon. We won’t get to see it because the Moon won’t be up yet. The eclipse, such as it is, will be only visible from the eastern hemisphere of the Earth like Asia. Even then there won’t be much to see. In a penumbral eclipse the Moon only enters the Earth’s outer shadow, called the penumbra where sunlight is only partially cut off. Observers on the affected parts of the Moon would see the Sun only partially eclipsed. And anyone whose seen a partial solar eclipse will tell you that it doesn’t get that dark. So most penumbral eclipses go unnoticed unless one is told about them. This one less than 60% of the Moon will be immersed in the Earth’s penumbral shadow.

There will be two more penumbral lunar eclipses this year, both visible from the United States: July 5th when only 35% of the Moon’s diameter is immersed in the penumbra, and November 30th when 83% is immersed.

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

01/10/2020 – Ephemeris – Eclipses today and to come

January 10, 2020 1 comment

I usually create these posts on the evening before the Ephemeris program airs on Interlochen Public Radio, though I record and post the audio programs the prior Sunday evening.  Wednesday we learned that my 102 year old mother-in-law Edith DelRaso was back in the hospital wit pneumonia after being released from the hospital for the same complaint This time it was worse.  My daughter, younger granddaughter and I headed south to Grand Rapids.  This lady had outlived all her many siblings, her husband and all but one of his siblings, and two of her three children, including my wife Judy.  She was ready to go.  At about 5:15 p.m. she breathed her last peacefully.  After a couple of hours with the gathered family we headed out to a favorite restaurant.  The weather in the Grand Traverse Area was worsening, so I got talked into staying in GR with my brother and his wife, and to head back today, so I missed posting this last night.  As a sad coincidence my niece’s father-in-law had a massive heart attack and eventually died at about the same time in Detroit. A sad day all around.

On with the show.

Ephemeris for Friday, January 10th. Today the Sun will be up for 9 hours and 2 minutes, setting at 5:21, and it will rise tomorrow at 8:18. The Moon, at full today, will rise at 5:20 this evening.

Later on this afternoon there will be a lunar eclipse, one of 4 this year. All of these are penumbral eclipses where the Moon misses the dark inner shadow of the Earth and skims through the outer partial shadow, where the Sun’s light is only partially obscured by the Earth, showing a slight dusky appearance on the side nearest the dark shadow. Being daytime the Moon will not have rises for use to see it. We will be able to witness the last two. The first of these is early in the morning hours of July 5th and be barely visible, the second will be in the morning hours of November 30th. There will be two solar eclipses, neither of which will be visible here. However, next year there will be a solar eclipse where the Sun will rise partially eclipsed here and we’ll see the last half hour of it.

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

12/26/2019 – Ephemeris – The last eclipse of the decade occurred this morning in Asia

December 26, 2019 Comments off

Ephemeris for Thursday, December 26th. Today the Sun will be up for 8 hours and 48 minutes, setting at 5:07, and it will rise tomorrow at 8:19. The Moon is new today, and won’t be visible. |

Today’s new moon has already produced the last solar eclipse of the 2010s overnight, visible mostly in Asia. The first eclipse of the new decade, the 2020s, will be January 10th, a very slight lunar eclipse called a penumbral eclipse where the Moon appears slightly shaded, but will appear whole. That said, it occurs during our day time, so we won’t see it. We will have two more penumbral lunar eclipses visible from our area next year. In all there are 8 total or partial lunar eclipses visible from our area next decade. The first is a total eclipse May 26, 2021. There will be 6 solar eclipses visible from here next decade including the Total eclipse visible from the Mexican to Canadian borders on April 8, 2024. It will be a deep partial eclipse here.

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

07/12/2018 – Ephemeris – A partial solar eclipse today will be visible from south Australia

July 12, 2018 Comments off

Ephemeris for Thursday, July 12th. Today the Sun will be up for 15 hours and 18 minutes, setting at 9:27, and it will rise tomorrow at 6:09. The Moon is new today, and won’t be visible.

There’s a minor partial solar eclipse late tonight our time

for extreme southern Australia and Tasmania. This will be followed in two weeks with a total lunar eclipse for mostly Africa and Asia. Two weeks and a day after that their will be a partial solar eclipse from northeastern Canada to Asia. When is the next solar eclipse visible here in northern Michigan? That would be June 10, 2021. The Sun will rise with the eclipse more than half over with the Moon taking a big bite out of the left side of the Sun. It will be all over by 6:40 a.m. However, for Canada north of Minnesota, the Sun will rise as a ring of fire because the Moon won’t be big enough to block the entire disk of the Sun. But on April 8, 2024 the Sun will be totally eclipsed in the US from Texas to Maine.

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

02/15/2018 – Ephemeris – There are three solar eclipses this year, today is the first

February 15, 2018 Comments off

Ephemeris for Thursday, February 15th. The Sun will rise at 7:43. It’ll be up for 10 hours and 28 minutes, setting at 6:11. The Moon is new today, and won’t be visible. There will be a solar eclipse today that will be a partial blocking of the Sun for parts of Antarctica and southern South America. This is the first solar eclipse to occur since the Great American Eclipse last August. There are three solar eclipses this year and they are all partials with the core of the Moon’s shadow just missing the Earth to the north or south. This year there is another total lunar eclipse, but we will be facing the Sun in daytime when it happens and won’t be able to see it. That lunar eclipse will be visible in Europe and Asia July 27th. One of the other partial solar eclipses will occur 2 weeks before and the other two weeks after that lunar eclipse. That happens when the Moon passes very near the center of the Earth’s shadow.

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

Addendum

Circumstanced for eclipses.

There are two eclipse seasons a year at an average interval of 5.7 months. Usually there is a solar and a lunar eclipse at each season, unless there is a central lunar eclipse, when it can be bracketed by a partial solar eclipse about two weeks before and again after.

08/08/2017 – Ephemeris – Eclipse seasons

August 7, 2017 1 comment

Ephemeris for Monday, August 7th. The Sun rises at 6:36. It’ll be up for 14 hours and 23 minutes, setting at 8:59. The Moon, at full today, will rise at 9:00 this evening.

At two weeks before the great solar eclipse, the world is experiencing another eclipse, this one is a partial lunar eclipse where the Moon will just clip the northern part of the Earth’s shadow this afternoon our time. It will be mainly visible from Asia. Eclipses occur in seasons of about a month long that occur at a bit less than six month intervals, so eclipses will occur a little earlier next year to the this. That’s because the crossing points of the Moon’s and the Earth’s orbital planes regress slowly westward. In an eclipse season two eclipses will occur: a solar and a lunar eclipse. On rare occasion when a lunar eclipse occurs in the center of a season a partial solar eclipse can occur two weeks before and again after the lunar eclipse, but they will affect the opposite polar regions of the Earth.

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

05/05/2017 – Ephemeris – A preview of the upcoming total solar eclipse and two star parties this weekend

May 5, 2017 Comments off

Ephemeris for Friday, May 5th.  The Sun rises at 6:26.  It’ll be up for 14 hours and 25 minutes, setting at 8:52.  The Moon, 3 days past first quarter, will set at 4:44 tomorrow morning.

On August 21st this year there will be a total solar eclipse visible from a narrow band that crosses the continental United States from Oregon to South Carolina.  It will be a fantastic sight.  From around here the eclipse will be a deep partial eclipse with the moon covering 75% of the Sun’s disk.  This evening yours truly will show how to view the eclipse safely at the 8 p.m. meeting of the Grand Traverse Astronomical Society at the Northwestern Michigan College’s Observatory.

At 9 p.m. there will be a star party.  Tomorrow night there will be, weather permitting a 9 p.m. star party that will be held at the Interlochen Center for the Arts at the soccer field, on the Duck Lake side of the Campus.  Parking is off Lyon Street.

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

03/27/2017 – Ephemeris – 5 more new moons before the Great American Total Solar Eclipse!

March 27, 2017 Comments off

Ephemeris for Monday, March 27th.  The Sun will rise at 7:32.  It’ll be up for 12 hours and 31 minutes, setting at 8:04.  The Moon is new today, and won’t be visible.

The Moon will be officially new at 10:57 this evening.  Later this year there will occur at total solar eclipse visible from a narrow path the crosses the United States from Oregon to South Carolina.  It will cross the cities of Casper Wyoming, Kansas City, just south of St Louis, Carbondale, Illinois; Nashville, Columbia and Charleston South Carolina.  Carbondale is about the closest spot to us at about 600 miles.  We will see about 75-80 percent of the Sun blocked by the Moon here in northern Michigan.  The is generally a solar eclipse about every six new moons, the exception is an occasional solar eclipse on two consecutive new moons, except they will occur in opposite polar regions and are rarely total.  The Moon’s orbit is tilted by 5° to the Sun’s path.  This time the Moon is way south of the Sun.

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

02/27/2017 – Ephemeris – The Great American Eclipse, August 21, 2017

February 27, 2017 1 comment

Ephemeris for Monday, February 27th.  The Sun will rise at 7:22.  It’ll be up for 11 hours and 5 minutes, setting at 6:28.  The Moon, 1 day past new, will set at 7:52 this evening.

We didn’t get a chance to see yesterday’s annular eclipse of the Sun, since it occurred mostly in the South Atlantic Ocean.  But it’s a wake up call for those of us who chase the Moon’s shadow, that the Great American Eclipse is a bit less than 6 months away.  August 21st to be exact.  Here in northern Michigan the Sun will be 75% or so covered by the Moon at peak.  For me it’s 100% or nothing.  The path where the Sun will be totally eclipsed will run from Oregon to South Carolina.  I’ve seen totality four times from 1963 to 1979 and accumulated 8 ½ minutes of time basking under the shade of the Moon.  Well not basking, for those were hectic magical times, not to be missed.  And come hell or high water I will strive to add another 2 plus minutes to that total.

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