07/13/2018 – Ephemeris – Sun ‘n Star Party set for tomorrow at the Sleeping Bear Dunes National Lakeshore

July 13, 2018

Ephemeris for Friday, July 13th. Today the Sun will be up for 15 hours and 17 minutes, setting at 9:26, and it will rise tomorrow at 6:10. The Moon, 1 day past new, will set at 10:04 this evening.

Tomorrow afternoon and evening will be what we call a Sun & Star Party at the Sleeping Bear Dunes National Lakeshore Hosted by the Grand Traverse Astronomical Society and the rangers of the park. This event will be held at the Dune Climb. 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, looking for sunspots, and another showing the chromosphere above it in the light of hydrogen giving a completely different view.

Starting at 9 p.m. will be a star party, actually mostly a planet party, viewing the planets Venus, Jupiter and Saturn, plus near the end of the night, Mars. There will be other celestial wonders visible in the deepening twilight. If cloudy one or both events will be cancelled. The astronomers will be back Sunday night if that night is clear.

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. Venus will be high enough to clear the dune for during the day and early evening.

Setting up my telescopes at the Dune Climb

My equipment at the Dune Climb on October 21, 2017. My 11″ Dobsonian is in the foreground. The tripod for my Celestron 8 is laying on the ground behind it yet to be set up.
I pointed the Dobsonian at a variety of deep sky objects, while the C8 was pointed to Saturn and tracking that night.
