09/26/2014 – Ephemeris – Mars meets its rival

September 26, 2014 Comments off

Ephemeris for Friday, September 26th.  The sun will rise at 7:34.  It’ll be up for 11 hours and 58 minutes, setting at 7:32.   The moon, 2 days past new, will set at 8:45 this evening.

The planet Mars and the bright star Antares will appear at their closest tomorrow night.  The name of the star Antares means “Rival of Mars”.  “Ant” meaning anti, “Ares”, the Greek equivalent to the Roman god Mars.  This is about a 26 month recurrence, give or take.  Usually Mars is way brighter than Antares, or way dimmer.  This time Mars and Antares are the same brightness.  Both planet and star have the same color, kind of a faded orange color, made redder by being low in our sky which drains even more of the blue out.  The reason Mars is red is that its surface is rusty.  Antares is another matter.  It is a cool red giant star.  Well, cool on the outside by hotter than the sun’s interior on the inside where it’s changing helium into carbon and oxygen for power.  Hint:  Mars is always on top.  Also tomorrow night the crescent Moon will be just to the right of Saturn.

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

There will also be exhibits and free stuff from NASA for the kids.

09/25/2014 – Ephemeris – Capella rising

September 25, 2014 Comments off

Ephemeris for Thursday, September 25th.  The sun will rise at 7:33.  It’ll be up for 12 hours and 1 minute, setting at 7:34.   The moon, 1 day past new, will set at 8:13 this evening.

A bright star called Capella has slowly been rising in the northeastern sky in the evenings for the past few months.  At 9 p.m. now it is low in the north-northeast far below the letter “W” shaped constellation of Cassiopeia.  This winter Capella will be overhead the highest of winter’s seven brilliant first magnitude stars.  Capella never quite sets for anyone north of Ludington.  It is what is called a circumpolar star.  Due to its brightness, and being the closest first magnitude star to the north pole, Capella appears to move slowly as the earth rotates, and spends summer and autumn evenings close to the horizon, and has in years past elicited a few phone calls and other queries about that ‘bright object in the northeast’.  When it’s higher the rest of its constellation Auriga the Charioteer will be visible.

09/24/2014 – Ephemeris – Where are the bright planets this week?

September 24, 2014 Comments off

Ephemeris for Wednesday, September 24th.  The sun will rise at 7:31.  It’ll be up for 12 hours and 4 minutes, setting at 7:36.  The moon is new today, and won’t be visible.

Let’s take our weekly look at the bright planets.  Mars and Saturn are in the southwestern sky at 9 p.m. with Saturn to the right and a bit below Mars by 17 degrees, about the two widths of your fist held at arm’s length.  Saturn will set at 9:38 p.m.  Saturn is in Libra, while Mars is in Scorpius.  Mars is closing in on a star that has the identical color, and this year the same brightness, its rival Antares.  Indeed that’s what the star’s name means:  Ant as in anti, Ares the Greek god of war, and the counterpart of the Roman Mars.  They will be closest Saturday.  Mars will set at 10:13..  In the morning sky brilliant Jupiter will rise in the east-northeast at 3:23 a.m., while Venus, will rise in the east at 6:51 a.m. only 42 minutes before the sun.  I’m not sure you’ll see it.

09/23/2014 – Ephemeris – NASA’s MAVEN satellite is in orbit of Mars

September 23, 2014 Comments off

Ephemeris for Tuesday, September 23rd.  The sun will rise at 7:30.  It’ll be up for 12 hours and 7 minutes, setting at 7:37.   The moon, 1 day before new, will rise at 7:53 tomorrow morning.

Last Sunday evening the MAVEN spacecraft fired its six main engines in alternating pairs for 33 minutes and was captured by Mars, entering orbit around the Red Planet.  MAVEN is one of those NASA acronyms, it stands for Mars Atmospheric and Volatile EvolutioN   Once in a capture orbit, the orbit will be changed from a 33 hour orbit to a 4 ½  hour a science orbit.  It will investigate how Mars lost its original atmosphere which was dense enough to support liquid water to the thin carbon dioxide atmosphere it has today.  It has several duties October 19th when Comet Siding Spring passes Mars to detect the interaction of the comet’s atmosphere with that of Mars.  There are no cameras* on Maven, just hard data will be returned.

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

Addendum

* Actually I was mistaken.  There is an Imaging Ultraviolet Spectrograph aboard which will take images in the ultraviolet of Mars upper atmosphere.

09/22/2014 – Epmemeris – Autumn begins tonight

September 22, 2014 Comments off

Ephemeris for Monday, September 22nd.  The sun will rise at 7:29.  It’ll be up for 12 hours and 10 minutes, setting at 7:39.   The moon, 2 days before new, will rise at 6:54 tomorrow morning.

Welcome to the last, almost full, day of summer.  The Sun will reach the autumnal equinox point in the sky at 10:30 this evening.  At that moment the Sun will cross the celestial equator, a projection of the Earth’s equator, heading southward.  All locations on the earth except two will experience 12 hours of daylight and 12 hours of night.  Well they would if the Earth didn’t have an atmosphere and sunset and sunrise were defined differently.  The two locations that don’t experience equal night, which is what equinox means, are the north pole where the sun will be setting and the south pole where the sun will be rising.  For us in the northern hemisphere daylight hours will be shorter and the Sun will peak lower in the south each day until the December solstice.

09/18/2014 – Ephemeris – The constellation Pegasus the aerobatic horse

September 18, 2014 Comments off

Ephemeris for Thursday, September 18th.  The sun will rise at 7:24.  It’ll be up for 12 hours and 22 minutes, setting at 7:47.   The moon, 3 days past last quarter, will rise at 3:02 tomorrow morning.

Rising 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, a fascinating constellation in its own right.

09/16/2014 – Ephemeris – My wife Judy passed away last Saturday

Note:  This is the transcript of the program that went out over the air:

This is Bob Moler with Ephemeris for Tuesday, September 16th.  The sun will rise at 7:22.  It’ll be up for 12 hours and 28 minutes, setting at 7:51.   The moon, 1 day past last quarter, will rise at 1:12 tomorrow morning.

The love of my life, Judy passed away last Saturday after 48 years of marriage.  When I met her, arranged, by my sister, who herself succumbed to cancer last month, she didn’t know much about astronomy, about the same as is seen from our schools today.  I was working at the planetarium in Grand Rapids at the time and we went in after hours and viewed the sky.  Using flash cards I made up, she learned the constellations.  After we were married and I came back from the Air Force, she got a job as the planetarium director’s secretary and sales clerk.  She took the college Astronomy 101 course, and even produced a planetarium show for young kids using kids drawings projected on the dome for illustration.

This the extended version, some of what what I really wanted to say:

Judith Ann Moler 1943-2014

The love of my life, Judy passed away last Saturday, September 13, 2014 at the age of 71, after we’d been married 48 years.  I met her, arranged, by my sister Shirley, who herself succumbed to cancer last month.  It was kind of a mercy dinner to take this guy (me) out before he entered Air Force for basic training.  Shirley said I pretty much ignored her on previous occasions, but this time I was smitten.  I’m a pretty much buttoned down guy with the ladies, but it was maybe because I was going to change my life by entering the Air Force that opened me up.
After a few dates I told her I had this, um, problem.  I liked to go out on dark nights and observe the heavenly bodies.  She could join me or stay inside where it’s warm.  She gamely joined me.  I suspect it was to make sure these heavenly bodies were celestial and not terrestrial.  (Just kidding).  Judy didn’t know much about astronomy when we met, about the same as we see from our schools today.  I was working at the Planetarium of the Grand Rapids Public Museum at the time and we went in after hours and viewed the sky.  Judy got to make up her own constellations.  Later, using flash cards I made up, she learned many of the brighter real constellations.

After we were married and I got out of the Air Force we came back to Grand Rapids I got a job with NCR and Judy got a job as the planetarium director’s secretary and sales clerk.  By then the planetarium had a name, the Roger B. Chaffee Planetarium, named for the Grand Rapids astronaut who died in the Apollo 1 fire in 1967.  Judy took the college Astronomy 101 course, and even produced a planetarium show for young kids using kids drawings projected on the dome for illustration.

She joined with us in trips to view the total solar eclipses of 1970 and 1972, but gave up her seat on the small plane we chartered in 1979 to view the total solar eclipse in February that year, being not too keen on flying, especially in small planes.  She even found a pilot we nicknamed, “Crash” LaMar, to fly the 5 of us brave souls to North Dakota to view this eclipse.  He could fly just fine, but had a problem keeping the wing tips from hitting the high snow banks when taxiing at the Bottineau, ND airport. I recall that once we had to get out and push, or was that my imagination?

We moved to the Traverse City area in 1971 to follow my job at the time working for NCR.
Around 1980 I was approached by the head of the Science and Math department Joe Rogers, at Northwestern Michigan College (NMC) to teach their 100 level astronomy course.  By then I had programs on the public radio station WIAA for 5 years, so my name was out there as an astronomical expert.  The problem was that I had never had any formal astronomical training*, despite that they hired me.  My other problem was that I frequently had to work out of town, so Judy stepped in to substitute teach on those nights I was out of town.  Actually she had more “formal” astronomy training than I did.

Judy was an instrumental part of the founding and operation of the Grand Traverse Astronomical Society (GTAS), started in 1982 and many years thereafter.  She held down the fort at the NMC Observatory with other members of the GTAS on the night in May 1983 when Comet IRAS-Araki-Alcock buzzed 3 million miles from the Earth and the public wanted to see it because Paul Harvey featured it on his newscast, when I abandoned them and snuck out to the less known Leelanau School’s Lanphier Observatory in Glen Arbor to photograph the comet in peace.  I know, it wasn’t nice of me.

In 1986 our family flew down to Miami and drove down to Key Largo to join the teacher and students from the Leelanau School to observe Halley’s Comet at its closest to the Earth, which was too far south to see from Traverse City.  I had the brilliant or cockamamie idea of splitting our 24 hour days into two 12 hour days.  A daytime day to explore and enjoy the Keys and a night time day to observe the comet.  Judy gamely went along with it: 8 hours up and 4 hours of sleep then repeat.  I found that it worked for me, at least for the 6 days we tried it.  Judy, at least, didn’t complain, but our daughter couldn’t handle it.  She went on our day trips, but stayed at our resort sleeping all night.  Beside viewing and photographing Halley’s Comet, which lost its tail that week (bummer), we visited Theater of the Sea, Key West and toured the coral reefs in a glass bottomed boat, and the Everglades.

We had many more adventures, but these have come to mind now.

* I’m not self taught.  My astronomy education comes via the members of the Grand Rapids Junior Astronomy Club and my close association with John Wesley, a true genius, and Donn Cuson, and members of the Grand Rapids Amateur Astronomical Association, and one of its founding members the late Evelyn Grebel, who let me tinker with the planetarium in its early days, and countless others including my still good friends Jim and Evie Marron at whose home Judy and I watched Neil Armstrong and Buzz Aldrin of Apollo 11 work on the Moon’s surface, and my friend and sometimes antagonist Dave DeBruyn, now Emeritus Director of the Chaffee Planetarium.

I’ll have more of these remembrances in the days to follow, maybe with better sentence structure,  but they will not be filed under Ephemeris.  Look for the category Memories and the tag Judy.  It’s my way of coping and healing.

Obituary for Judith A. Moler

09/15/2014 – Ephemeris – The mer-goat Capricornus

September 15, 2014 Comments off

Ephemeris for Monday, September 15th.  The sun will rise at 7:21.  It’ll be up for 12 hours and 31 minutes, setting at 7:53.   The moon, at last quarter today, will rise at 12:21 tomorrow morning.

Nearly 2000 years ago the southernmost of the constellations of the zodiac was Capricornus the water goat.  That’s why the latitude on the earth where the sun is overhead on the winter solstice is called the Tropic of Capricorn.  Not any more, Sagittarius, one constellation west and due south at 9 p.m., has that honor today.  Actually Capricornus does need the press.  It’s large, but made up of dim stars.  To me it looks like a 45 degree isosceles triangle, long side up, but which all the sides are sagging.  The constellation is found low in the south at 11 p.m. and tilted a bit from the upper right to the lower left.  The image that is supposed to be represented by the stars is that of a goat whose hind quarters are replaced by a fish’s tail, not a mermaid but a mer-goat.

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