Ephemeris: 07/26/2024 – View the Sun from the Sleeping Bear Dunes tomorrow

July 26, 2024 Comments off

Sorry, I’ve posted this a bit late.

This is Ephemeris for Friday, July 26th. Today the Sun will be up for 14 hours and 51 minutes, setting at 9:14, and it will rise tomorrow at 6:24. The Moon, 1 day before last quarter, will rise at 12:03 tomorrow morning.

Tomorrow, Saturday, July 27th there will be solar viewing at the Sleeping Bear Dunes National Lakeshore, at the Dune Climb from 3 to 6 PM. Park Rangers will be joined by members of the Grand Traverse Astronomical Society with their specially filtered telescopes to view the sun safely. This is a period of great solar activity. Remember the Northern Lights of last month? Solar filtered telescopes will safely view the surface of the sun, called the photosphere and sunspots, while the society also has two special solar telescopes with which to view the layer of gas above the surface called the chromosphere and prominences which look like flames coming off the chromosphere. This is the last of the two solar observing opportunities this summer.

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

Addendum

The Sun in the light of hydrogen seen Friday at about 2:24 in the afternoon Eastern Time. This is the kind of view visible in the solar telescopes that will be at the Sleeping Bear Dunes. By tomorrow there’ll be a bit of rotation of the Sun. The little dark streaks on the face of the Sun are called filaments. When seen off the edge of the Sun are called prominences. This view does not show the prominences very well, however there are quite a few and one very large one at this time. Prominences do change with time, and they would not be representative of what would you would see tomorrow. Credit: Big Bear Observatory, California.
