![]() But even a 99% partial eclipse pales in comparison to a total one. Outside the path of totality nearly all of North America will get a partial solar eclipse. ![]() Birds and farm animals, thinking dusk has settled, return to their nests and barns, and bats come out to feed. Bright stars and planets shine forth, and the air temperature drops noticeably. The sky darkens to a deep twilight blue, with yellow, orange, and pink sunrise/sunset colors on the horizon in all directions. At the beginning and end of totality, the thin middle layer of the Sun’s atmosphere, the chromosphere, blazes in an arc of ruby red. When the Moon covers the Sun's bright face, the corona is definitely the main attraction, but there’s so much more to the experience. The corona is always there, but we usually can’t see it because the photosphere is about a million times brighter and drowns it out. It is hauntingly beautiful and, without doubt, one of the most awesome sights in all of nature. A partial solar eclipse will be visible to nearly everyone in North America fortunate to have cloud-free skies.ĭuring a total solar eclipse, the Moon blocks the Sun’s bright face - the photosphere - briefly revealing our star’s outer atmosphere: the shimmering corona, or “crown.” Made of rarefied gas heated to millions of degrees, with its atoms highly ionized (stripped of electrons), the diaphanous corona gets sculpted into streamers and loops by the Sun’s powerful magnetic field and shines with a light seen nowhere else. This time the Moon's dark central shadow, about 115 miles wide, will cross Mexico, sweep northeast from Texas to Maine, and then darken the Canadian maritimes. Remarkably, another total solar eclipse is coming to North America on April 8, 2024, just seven years after the last one. The 2017 total solar eclipse was the first to touch the "Lower 48" since 1979 and the first to span the U.S. Courtesy Rick Fienberg / TravelQuest International additional processing by Sean Walker, Sky & Telescope. ![]() At all other times, though, a safe solar filter is required to observe or photograph the Sun. No filter was used during the exposures, as totality is about as bright as the full Moon and just as safe to look at. The star to the left (east) of the eclipsed Sun is Regulus, the brightest star in the constellation Leo. This is a composite of short, medium, and long exposures, as no single exposure can capture the huge range of brightness exhibited by the solar corona. The total phase of the August 21, 2017, solar eclipse as seen from Madras, Oregon. If you were outside that path under clear skies somewhere else in North America (or northern South America), perhaps you saw a partial solar eclipse that day. Monday, April 8, 2024: Mark Your Calendar!ĭo you remember the total solar eclipse that crossed the continental United States from coast to coast on August 21, 2017? If you lived in, or traveled into, the 70-mile-wide path of totality, where the Moon completely blocked the Sun and turned day into night for 2 minutes or so, you undoubtedly remember it well. The difference between a total solar eclipse and a partial one is literally the difference between night and day, so get yourself into the path of totality if you can. Yellow curves indicate how much of the Sun is covered by the Moon outside the path of totality. The solar eclipse of April 8, 2024, will be total in a narrow path from Mexico to the Canadian maritimes and partial to the northwest and southeast.
