When the sun rises in north central Illinois tomorrow morning, it will be partially eclipsed. Sunrise will be at 5:22am Thursday. A minute later, careful observers should notice what looks like a chunk missing from the sun on the left side. The moon is crossing the sun’s disk leaves it 15 minutes after that.
Anyone looking at the sun should use a viewing filter made specifically for it, or project an image of the sun with a pinhole projector. That’s to protect the eyes from ultraviolet and infrared rays. Such rays can damage the eyes without causing any pain. If you still have a filter from the solar eclipse of 2017, make sure it’s in good condition with no holes or cracks. Do not stack up sunglasses or film negatives.
While sunrise brings the end of the eclipse here, it will actually be the beginning of the eclipse whose central path will cross eastern Canada, northern Greenland, the North Pole, and part of Russia. Along the central path, people will see a ring of sunlight around the moon’s disk.
