![]() Our Moon is getting in on the act, albeit with a much more subtle display in the form of a penumbral eclipse. We’re fortunate that the night of July 4 is expected to be clear, and not just for the traditional booms and flashes of celebratory fireworks. Uncategorized annular eclipse, eclipse, Moon, solar eclipse, Sun Subtle lunar eclipse July 4 – 5Ī penumbral lunar eclipse occurs when the Moon passes through the thin outer shadow - penumbra - Earth casts out into space. Failure to use appropriate filtration may result in permanent eye damage or blindness!” - NASA: Eye Safety During Solar Eclipses Do not attempt to observe the partial or annular phases of any eclipse with the naked eye. Even when 99% of the Sun’s surface is obscured during the partial phases of a total eclipse, the remaining photospheric crescent is intensely bright and cannot be viewed safely without eye protection. Partial eclipses, annular eclipses, and the partial phases of total eclipses are never safe to watch without taking special precautions. “The Sun can be viewed safely with the naked eye only during the few brief seconds or minutes of a total solar eclipse. If you see any dots of light through the viewer film, throw those glasses out!ĭo NOT look at the sun through sunglasses, even multiple sets of sunglasses, or photo negatives, Compact Discs, or anything other than certified eclipse viewing equipment! Pinhole and other projection techniques can be used safely since the viewer is looking at a projection and not the sun itself. If you have eclipse glasses from a recent solar eclipse, those should be just fine - just make sure there are no pinholes or other damage to the plastic film “lenses”! You can check for damage by holding the eclipse viewer at arm’s length and looking at a bright lightbulb. How can you watch the eclipse? With great care! At no time during our partial solar eclipse will it be safe to watch the event without vision protection. Partial Eclipse of the Sun, Augthis image rotated to resemble what viewers might see at dawn, June 10, 2021. How can you watch the eclipse? With great care! Much of the solar disk will be visible but the curved edge of Moon will take a bite out of one side. What we may see at dawn and diminishing thereafter, is a partial solar eclipse - looking a bit like the chomping character from the classic PAC-MAN video game. An annular eclipse takes place when Moon is at higher points in its orbit when it passes between Earth and Sun, too distant and small to form a perfect cover, allowing a brilliant ring of our star to shine. The eclipse ends at 6:35 AM as Moon completes its passage across Sun.Ī total eclipse of the sun takes place when Earth’s Moon, at normal orbital distances, covers the solar disk completely and blocks all but the glowing corona from view. In our area, sunrise will be at 5:55 AM (EDT) with the eclipse already at its maximum for us. In fact, no place in the United States will see the complete circle, or annulus, of Sun around Moon. Unfortunately, even with clear skies we will not see the “ring of fire” that is the namesake look of this type of eclipse.

Throughout the eclipse, the Moon is found in the constellation Libra.Īnnular Eclipse of the Sun. Totality lasts for an hour and a half before the Moon begins to emerge from the central shadow. ![]() An hour later, entirely within the umbra, Moon is a copper, or red-orange color. The real action begins when the Moon starts to disappear as it enters the umbra at about 10:28 p.m. The Moon’s appearance isn’t affected much by the penumbra but careful observers may note a change in the full Moon’s appearance. ![]() Though direct sunlight is blocked whilst in the umbra, Moon is illuminated by light refracted and filtered by Earth’s atmosphere, colored by all of the globe’s sunrises and sunsets. The umbra, the deep central cone of Earth’s shadow, is where Sun is completely hidden. The penumbra is the part of the Earth’s shadow where the Sun is only partially covered by Earth. The Moon moves right to left, passing through the penumbra and umbra, leaving in its wake an eclipse diagram with the times at various stages of the eclipse.
