2023-2024 NASA Solar Eclipse Flyers and Fact Sheets

The predicted path of the October 14, 2023 annular eclipse and the April 8, 2024 total solar eclipse. Duration of Greatest Eclipse for Annular: 5 min 17 sec (18:00 UT=13:00 CDT=1 p.m. CDT) Location of Greatest Eclipse: 11 deg 22 min N; 83 deg 6 min W (Central America) Duration of Greatest Eclipse for Total: 4 min 28 sec (18:18 UT=13:18 CDT=1:18 p.m. CDT) Location of Greatest Eclipse: 25 deg 17 min N; 104 deg 8 min W (Mexico) Path of Totality Path of Annularity The next total solar eclipse visible over the continental United States will be on April 8, 2024. Never look directly at the Sun unless you have filters that you know are safe.

A solar eclipse happens when the Moon—as it orbits Earth—fully or partially blocks the light of the Sun, thus casting its shadow on Earth. What is a Total Solar Eclipse? As observed from Earth, if the Moon is closer to Earth in its orbit and is aligned between Earth and Sun, it appears to be the same size as the Sun and a total solar eclipse occurs. The Moon blocks all the bright light from the surface of the Sun and the corona can be seen. What is an Annular Eclipse? As observed from Earth, an annular eclipse occurs when the Moon is aligned between Earth and Sun and is far enough from Earth to appear smaller than the Sun so that a ring (annulus) of sunlight remains visible around the Moon.

Israel Strange Shadows! Sunlight through trees produces projected crescents during partial phases. Mirror in an Envelope Slide a mirror into an envelope with a ragged hole cut into the front. Point the mirror toward the Sun so that an image is reflected onto a screen at least 5 meters (about 15 feet) away. The longer the distance, the larger the image. Do not look at the mirror, only at the screen. For any total solar eclipse, if the Sun is not 100% covered in your area, please travel to an area inside the path of totality to experience a fully eclipsed Sun. You will be disappointed if you don’t!
