Totality - Since the Moon crosses the southern half of the shadow's core and not dead-center, you should see a noticeable difference in brightness and color between its southern hemisphere, located near the umbra's periphery, and the northern hemisphere, which almost touches the center. For predictions and a chance to share your observations, visit Roger Sinnott's Useful Projects for a Lunar Eclipse.ĭuring totality the Moon appears in Libra approximately halfway between Alpha (α) Librae, better known as Zubenelgenubi, and Antares in Scorpius. Telescope users can also time when the shadow's edge passes over individual craters to help determine how changes in the Earth's atmosphere cause the expected diameter of the umbra to vary. You'll need a small telescope to see the coloration, but it's surprisingly obvious once you look for it. Partial eclipse - At what point does the shadowed portion of the Moon appear red in binoculars? With the naked eye? Because it absorbs red light, the atmospheric ozone layer often imparts a turquoise hue to the edge of encroaching umbral shadow.
When will it first become visible - 30 minutes before partial eclipse? 15 minutes? Can you detect color and depth of shading or is it a uniform gray? Penumbral eclipse - Look for a subtle shading along the eastern third-to-half (bottom left for U.S. At right, the penumbral shadow shades the Moon during the Februeclipse. Some sunlight leaks into the shadow's edge, creating a fuzzy, pale penumbral border. The inner portion represents the umbra, where the trunk blocks all direct sunlight. Understanding the penumbral shadow is easy. Happily, 2022 is one of those "typical" years, with a second total eclipse falling on November 7–8 and also visible in the Americas. That typically happens twice a year with a maximum of three and minimum of zero.
#LUNAR ECLIPSE TIME NEW JERSEY FULL#
If the Moon happens to be full at the same time that it crosses at or near a node, it will pass directly into Earth's shadow, and we'll see an eclipse. The two orbits intersect at two places called nodes. Total eclipses would occur at every full Moon if the Moon's orbit were coplanar with the Earth's, but it's inclined by 5.1°. Complex interactions between the Sun, Earth, and Moon cause the nodes to precess around the ecliptic with a period of 18.6 years. If the Moon is in new phase, a solar eclipse results. If full Moon occurs within about 17° of a node crossing, an eclipse will occur somewhere on Earth, either partial, total, or penumbral. The moon's orbit briefly passes through the plane of Earth's orbit (ecliptic plane) twice each lunation - moving north of the plane at the ascending node and south of it at the descending node.
