06/08/2021 – Ephemeris – The Sun will be partially eclipsed as it rises Thursday

June 8, 2021 Comments off

This is Ephemeris for Tuesday, June 8th. Today the Sun will be up for 15 hours and 29 minutes, setting at 9:26, and it will rise tomorrow at 5:57. The Moon, 2 days before new, will rise at 5:22 tomorrow morning.

Thursday morning we in Michigan will witness the last moments of a solar eclipse as the Sun rises. The Sun will be partially eclipsed at sunrise north of a line from North Dakota to South Carolina. For those in a path that will run from the north shore of Lake Superior across western Ontario, through parts of Hudson Bay, to clipping the North Pole and into Siberia will see an annular eclipse. That is, the Moon is too far away, and small to cover the face of the Sun, leaving a bright ring or annulus. A ring of fire, some would say. For us, the Sun will rise around 5:57 am with the Moon taking a big chunk out of its left side. That chunk will recede until the Sun will appear whole again around 6:42 am. I’ll discuss how to view this eclipse tomorrow.

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

The visibility map for the June 10, 2021 annular solar eclipse

The visibility map for the June 10, 2021 annular solar eclipse. In an annular eclipse, the Moon is too far away and appears too small to cover the face of the Sun. So, at maximum, a ring of bright Sun surrounds the Moon. It’s sometimes called a ring of fire. For locations within the big red floppy figure 8, the eclipse either ends near sunrise (bottom lobe) or starts near sunset (top lobe). The double line with the ellipses in it is the path of where the ring is visible, the path of annularity. Locations within the grid on the right will see a partial eclipse.

04/29/2014 – Ephemeris – Today’s weird annular eclipse

April 29, 2014 Comments off

Ephemeris for Tuesday, April 29th.  The sun rises at 6:35.  It’ll be up for 14 hours and 9 minutes, setting at 8:44.  The moon is new today, and won’t be visible.

This event has already happened,  and there was now way to be able to get to a spot too see its maximum effect.  What I’m talking about was this morning’s weird annular eclipse of the sun.  Australia saw the partial phase.  An annular eclipse is one in which the moon is too far away to completely fill the face of the sun at maximum eclipse, leaving a bright ring of the uneclipsed sun around the moon.  The path of annularity will just graze the earth over a spot in Antarctica.  The center of this annular shadow called an antumbra, a new word I learned from descriptions of this eclipse, will just miss the earth. As far as I know no one had  gone to the spot where the annular effect can be seen, so remote is its location.  It kind of reminds one that the earth is a ball in space.

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