09/03/2021 – Ephemeris – Tonight: Virtual Star Party via Zoom with the Sleeping Bear Dunes National Lakeshore

September 3, 2021 Comments off

This is Ephemeris for Friday, September 3rd. Today the Sun will be up for 13 hours and 7 minutes, setting at 8:15, and it will rise tomorrow at 7:09. The Moon, 3 days before new, will rise at 4:01 tomorrow morning.

Tonight the Sleeping Bear Dunes National Lakeshore and the Grand Traverse Astronomical Society will host an online star party this evening starting around 9 pm via the Zoom app available for Android smartphones, iPhones and computers. Instructions for joining are on the society’s website, gtastro.org. Images will be captured live, if it’s clear, from Northwestern Michigan College’s Joseph H Rogers Observatory. The images will be pretty much what is seen at the telescope eyepiece, and definitely not Hubble Space Telescope quality, which take weeks to process. Visible will be the Venus, Jupiter, Saturn and wonders of the Milky Way, some really neat star clusters, and nebulae, that is clouds of gas and dust in the Milky Way.

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

Addendum

Also, the planets Venus, Saturn and Jupiter will be visible during the session.

This post is going out at Midnight the night before, and the forecast is for clouds. It is possible that we will reschedule for Friday the 10th. If so, I’ll have a post about it then.

This is Bob Moler with Ephemeris for Friday, August 13th. Today the Sun will be up for 14 hours and 8 minutes, setting at 8:51, and it will rise tomorrow at 6:44. The Moon, 2 days before first quarter, will set at 11:36 this evening.

The Grand Traverse Astronomical Society will try again to hold a virtual star party starting at 9:30 pm tonight via the Zoom app on the Internet. We were clouded out last Friday night. Jerry Dobek, professor of astronomy at Northwestern Michigan College, will host the event with the 16-inch telescope at the College’s Observatory and an imager, but only if it’s clear in Traverse City. It should feature a look at Venus and the crescent Moon to start. Saturn and Jupiter will be up by then, but they’re quite low in the sky. We might take another look at them later on when their images are steadier. The wonders of the Milky Way are all available. Instructions and a link can be found on the society’s website, www.gtastro.org.

The Southern Milky Way from Traverse City

The southern Milky Way from Aquila to Sagittarius taken from my backyard with light pollution from businesses on US 31 in Chums Corners and Grawn south of me.  I live about 7 miles west of the NMC Observatory. These bright lights are to its southwest and farther away. Click on the image to enlarge it.

The images will be pretty much what is seen at the telescope eyepiece, and definitely not Hubble Space Telescope quality, which take days to process. Visible will be the crescent Moon. Then we move out beyond the solar system into our galaxy for star clusters and beyond our galaxy into the distant galaxies of spring skies.

The Moon tonight. We’ll be looking at the Moon’s dark lava seas and other craters near the sunrise terminator.

We will be looking also at a few star clusters and out the thin side of our Milky Way Galaxy to lots of other galaxies.
