09/07/2018 – Ephemeris – Two astronomy events in the Grand Traverse region this weekend

September 7, 2018

Ephemeris for Friday, September 7th. The Sun will rise at 7:12. It’ll be up for 12 hours and 56 minutes, setting at 8:08. The Moon, 2 days before new, will rise at 5:35 tomorrow morning.

This evening the Grand Traverse Astronomical Society will hold its monthly meeting at the Northwestern Michigan College’s Rogers Observatory at 8 p.m. with a program featuring Dr. David Penney and his talk Large Impacts on the Earth. 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.

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.
