06/17/2016 – Ephemeris – Sun & Star Party Saturday at the Sleeping Bear Dunes

June 17, 2016

Ephemeris for Friday, June 17th.  Today the Sun will be up for 15 hours and 34 minutes, setting at 9:31, and it will rise tomorrow at 5:56.  The Moon, 3 days before full, will set at 4:58 tomorrow morning.

Tomorrow afternoon and evening will be what we call a Sun & Star Party at the Sleeping Bear Dunes National Lakeshore.  This event will be 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, 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 really a planet party, viewing the planets Jupiter, Mars and Saturn, plus the nearly full Moon.  A twilight talk will be given at 9 p.m. on how astronomy has been changed in the last 100 years by Einstein’s Theory of General Relativity, for the 100th anniversary of the National Park Service.

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