01/08/2021 – Ephemeris – There will be a virtual star party tonight

January 8, 2021 Comments off

This is Ephemeris for Friday, January 8th. Today the Sun will be up for 9 hours and 1 minute, setting at 5:20, and it will rise tomorrow at 8:19. The Moon, 2 days past last quarter, will rise at 4:31 tomorrow morning.

The Grand Traverse Astronomical Society will host a virtual star party at 8 pm tonight. It is via the Zoom app for smartphones, tablets or computers. Instructions and a link can be found on the society’s website gtastro.org. It will be hosted by Dr. Jerry Dobek, astronomy professor at Northwestern Michigan College. During a virtual star party the images are produced real time or near real time using a telescope mounted CCD camera. That is if it’s clear. If cloudy we’ll have a virtual, virtual star party using recently acquired images captured for his astronomy students. A couple of months ago we got a tantalizing look at the Great Orion Nebula as it rose in moonlight. Now it’s higher in the sky with no Moon. It should be spectacular!

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

02/05/2016 – Ephemeris – Women in astronomy night at the GTAS tonight

February 5, 2016 Comments off

Ephemeris for Friday, February 5th.  The Sun will rise at 7:57.  It’ll be up for 9 hours and 58 minutes, setting at 5:56.   The Moon, 3 days before new, will rise at 6:12 tomorrow morning.

Tonight there will be a meeting of the Grand Traverse Astronomical Society at Northwestern Michigan College’s Rogers Observatory, featuring a graduate from NMC and the astronomy program: Becky Shaw who will present a talk Women in Astronomy.  This is a second presentation of more female astronomers, the last was in November I especially recommend this for girls in school interested in the STEM fields, that is Science, Technology, Engineering and Math to find out the wonderful contributions these women have made.  Astronomy, by the way encompasses all the STEM fields.  The meeting starts at 8 p.m. and the observatory is located on Birmley Road, south of Traverse City.  At 9 p.m. the will also be star party if it’s clear.

Addendum

Appropriate to our speaker’s topic:  In the news now is Smith’s Cloud, discovered by Gail Smith (now Gail Bieger-Smith) in 1963 as an astronomy student at Leiden University in the Netherlands.   In new studies with the Green Bank (Radio) Telescope and the Hubble Space Telescope the velocity and composition of the cloud has been measured.  It somehow was ejected from the Milky Way some 70 million years ago, but it’s coming back!  In 30 million years it will crash back in, hitting the Milky Way’s other gas clouds and will probably cause a burst of star formation of maybe 2 million new stars.

What’s with the 5:59:59 time for the 7th?  This is what happens when you store and compute time as a binary computer value (base 2) and display it as a sexagesimal (base 60) number.  Thanks Sumerians.

08/20/2015 – Ephemeris – Library Lending Telescopes

August 20, 2015 Comments off

Ephemeris for Thursday, August 20th.  The Sun rises at 6:50.  It’ll be up for 13 hours and 50 minutes, setting at 8:40.   The Moon, 2 days before first quarter, will set at 11:30 this evening.

The Moon has always been a favorite target for binoculars and telescopes.  Tonight is no exception.  The trouble is that most inexpensive telescopes are overly complicated and hard to use.  One way to help the prospective telescope buyer is to try one and get used to a telescope before plunking down money for it.  In that regard The Grand Traverse Astronomical Society (GTAS) and Enerdyne of Suttons Bay have donated a telescope to the Traverse Area District Library and The Betsie Valley District Library.  The library’s themselves will determine how the telescopes will be lent out.  The first two telescopes are Orion StarMax 90mm TableTop telescopes, suitable for viewing the Moon and planets Saturn, Jupiter, Venus and Mars.

04/03/2014 – Ephemeris – Astronomy events in the Grand Traverse Region

April 3, 2014 2 comments

Ephemeris for Thursday, April 3rd.  The sun will rise at 7:19.  It’ll be up for 12 hours and 52 minutes, setting at 8:12.   The Moon, half way from new to first quarter, will set at 12:39 tomorrow morning.

This evening the Grand Traverse Astronomical Society or GTAS will be at the Boardman River Nature Center for “A Night at the Nature Center”.  This is a closed event sponsored by the Grand Traverse Conservation District, but it reminds me that the society hosts these types of events for schools, scouts and other youth groups along with other non-profit organizations.  We’re now lining up some summer reading clubs at at least two area libraries.  In the daytime we have that one great star the sun.  At night we have the rest of them including the Moon and planets.  If its cloudy we have hands on activities.  Contact the society at info@gtastro.org for more information.  The GTAS may also pop up at a summer festival near you.

Yours truly will present a talk, about the prospects for viewing Comet PanSTARRS at this evening’s meeting of the Grand Traverse Astronomical Society at Northwestern Michigan College’s Rogers Observatory starting at 8 p.m.  Comet PanSTARRS will appear low in the western sky starting about March 11th.  It is turning out at this point in time to be somewhat dimmer than expected.  But one thing about comets is that the do the unexpected.  I’ll also look at the asteroid close approach and the  destructive Russian meteor.  Starting at 9 p.m. Is our February star party at the observatory.  Highlights, if its clear will be the planet Jupiter and  the wonders of the winter sky including the Great Orion Nebula.  All are welcome.

A Star Bowl quiz will be held this evening between the NMC Astronomy Club and the Grand Traverse Astronomical Society at this evening’s meeting of the society at 8 p.m. at Northwestern Michigan College’s Rogers Observatory.  The society will accept anyone to help us.  These NMC students are smart.  After the Star Bowl there will be a viewing night starting at 9 p.m.  On tap if its clear will be the planet Jupiter.  Orion and its great nebula, a star nursery only 1400 light years away will be a wonderful sight with its clouds and wisps of gas and dust illuminated by a clutch of hot baby stars.  The Observatory is located south of Traverse City on Birmley Road off either Garfield or Keystone roads.
