06/01/2018 – Ephemeris – Presentation tonight: Cosmic rays and the quiet Sun

June 1, 2018 Comments off

Ephemeris for Friday, June 1st. Today the Sun will be up for 15 hours and 21 minutes, setting at 9:21, and it will rise tomorrow at 5:59. The Moon, 3 days past full, will rise at 11:57 this evening.

Tonight at 8 p.m. at the June meeting of the Grand Traverse Astronomical Society at Northwestern Michigan College’s Rogers Observatory, Observatory Director Jerry Dobek will be giving a talk on how the Earth is receiving more cosmic rays from outside the solar system now that the Sun is in its quiet phase. Cosmic rays are not like x-rays or other forms of electromagnetic radiation. They are particles, bare nuclei of atoms, some pretty heavy. They are a danger to airline crews who fly over the north pole daily. After the meeting, at 9 p.m. the society will host a star party to view the planets Venus and Jupiter. The observatory is located south of Traverse City on Birmley Road between Garfield and Keystone roads.
43rd Anniversary of Ephemeris!

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