08/22/2022 – Ephemeris – Sleeping Bear Dunes Star Party tonight!

August 22, 2022 Comments off

This is Bob Moler with Ephemeris for Monday, August 22nd. Today the Sun will be up for 13 hours and 43 minutes, setting at 8:36, and it will rise tomorrow at 6:54. The Moon, 3 days past last quarter, will rise at 2:43 tomorrow morning.

Weather permitting, a star party will be held tonight at the Sleeping Bear Dunes National Lakeshore at the Dune Climb starting at 8 pm. The star party will be hosted by the park rangers and the Grand Traverse Astronomical Society, who will bring their telescopes to view the heavens, including the planet Saturn and the wonders of the summer Milky Way. The telescopes will be setup in the parking area closest to the dune. While as twilight fades Saturn will be about the only object to view, as it gets darker more and more wonders of the Milky Way will be seen. They include star clusters of both kinds: young open clusters of a few hundred stars sparkling like diamonds and great, ancient globular clusters of hundreds of thousands of stars. Jupiter will rise later in the evening, around 10 pm.

The astronomical event times given are for the Traverse City/Interlochen area of Michigan (EDT, UT – 4 hours). They may be different for your location.

On to astronomical matters: Tomorrow night July 23rd there will be, weather permitting, a star party at Sleeping Bear Dunes National Lakeshore, this will take place at the Dune Climb. The star party is made possible by the rangers of the park and the Grand Traverse Astronomical Society. The society’s and member’s telescopes will take over the parking lot closest to the Dunes The event starts at 9 p.m., while it’s still light out and the location can be found. The park rangers will leave at 11, while the society members will stay longer.

Excerpt from the Sleeping Bear Dunes National Lakeshore calendar posting for August 23:

“These events will be cancelled if the sky is not visible due to weather conditions. The decision to cancel is usually made either three hours in advance or by 4:30 p.m. the day prior to the event. Please call park rangers at 231-326-4700, ext. 5005, for a voicemail message with the decision. For the early morning and late evening astronomy events, bring a flashlight for the walk to and from the event. Park rangers and GTAS staff will wear red glow bracelets at the events. For more information about the Grand Traverse Astronomical Society, go to http://www.gtastro.org/. “

Ephemeris for Friday, August 30th. Today the Sun will be up for 13 hours and 20 minutes, setting at 8:23, and it will rise tomorrow at 7:03. The Moon is new today, and won’t be visible.

The second Sun and star party in August at the Sleeping Bear Dunes National Lakeshore will be held at the Dune Climb tomorrow if it is reasonably clear. The solar portion will start at 4 p.m., while dark sky viewing will start at 9 p.m.. It will be hosted by the Park Rangers and the Grand Traverse Astronomical Society. The society’s new solar telescope can generally tease out some interesting detail from the currently quiet Sun. Later on the wonders of the Milky Way, which will span the skies from horizon to horizon will be seen, along with the planets Jupiter and Saturn. The park has one of the darkest skies in the Lower Peninsula, and the Milky Way is especially impressive this time of year.

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

Dune Climb Setup

This in the beginning of setup for the October 21, 2917 star party at the dune climb. Taken early while there was enough light. The dune blocks up to 12 degrees from the southwest to northwest, but the rest of the horizon is quite low.  Photo by the author.

The weather for this event is very iffy, so if it is cancelled members of the GTAS will have their telescopes at the Dune Climb Sunday night, if it is clear, to view the sky.  Though not an official star party, campers and the public to view the heavens.  For a voicemail on the status of the star party on Saturday please call 231-326-4700, ext. 5005.

After watching the impacts of Comet Shoemaker-Levy 9 into Jupiter in 1994 the public and space agencies began to take the possibility of an asteroid or comet impact on the Earth seriously. Dr. Penney will talk about evidence of such impacts on the Earth in the past. After the talk, at 9 p.m. there will be a star party to view the heavens including Saturn and Mars and wonders of the Milky Way. The observatory is located south of Traverse City, on Birmley Road between Garfield and Keystone roads.

From 4 to 6 p.m., the Sun will be featured using two types of telescopes, one showing the sun’s photosphere in what we call white light, hoping the Sun will produce a sunspot of two, and another showing the chromosphere above it in the light of hydrogen giving a completely different view with possibly more activity. Starting at 9 p.m. will be a star party, actually really a planet party, viewing the planets Venus, Jupiter and Saturn, plus the Moon. There will be other objects visible in the deepening twilight.  The event is due to the cooperation of the Grand Traverse Astronomical Society and the park rangers.

Update:  The Sun and Star Parties are subject to cancellation separately based on weather.  Check back to this here if there is a cancellation or call the park at 231-326-4700.  The park’s web page for this event is here.   If Saturday night star party is cancelled, some members of the society will hold their own observation session at the Dune Climb Sunday night.  Notification will be posted by 7 p.m. here if that event will take place.  We also invite anyone with a telescope and experienced in its use to join us.  For anyone who wants to have us look at their telescope or give them tips, come to our NMC Rogers observatory star parties which are listed on our society web site: http://www.gtastro.org. Those star parties are less hectic.
