On June 10, there’s an annular eclipse of the sun. This type of eclipse is also called a “ring of fire” eclipse, because the moon is too far from the earth to appear to block the entire solar disc, and instead appears to stand fully embraced by the sun’s corona. This eclipse will already be underway by the time the sun rises in northern Michigan (where I am), around 5:51 am, and though it will appear only as a partial eclipse for me, it’s worth getting up for because it’s the only eclipse of the 21st century that will cast its shadow over the North Pole, at the very top of the world.  Find out more from the American Astronomical Society at this link.
