Which of the following part of the sun is visible at the time of the eclipse

Viewing the Sun, except during the totality phase of a solar eclipse is only possible using reflected images or special filters. The filters are required to cut down light levels to avoid permanent eye damage and damage to equipment. Using a mylar filter the photosphere and sunspots are visible. Using a Hydrogen alpha filter on a telescope makes the chromosphere and prominences visible. There are four types of solar eclipse. A partial eclipse is where the Sun and Moon are not completely aligned and the Moon doesn't cover all of the Sun's disc. The Sun can only be safely viewed through filters. The other types of eclipse have partial phases before and after the central event. A total solar eclipse is where the Moon's disc is larger than the Sun's disc and can completely cover it. Only during the total phase is it safe to view with the naked eye. During totality the Sun's corona is visible. It is a spectacular sight indeed. A total eclipse can last over 6 minutes. For a few seconds just before and after totality, it is possible to see the chromosphere and prominences. An annular eclipse is where the Moon is too distant to completely cover the Sun's disc. It is possible to see the chromosphere and prominences. A hybrid eclipse is where the Moon's disc is about the same size as the Sun's disc. Hybrid eclipses are often annular when viewed from some places and total when viewed from others. Totality for a hybrid eclipse is usually less than a minute, but the chromosphere and pr...

The characteristic “ring of fire” ©iStockphoto.com/ssucsy Moon Casts a Shadow The Moon's shadow is not big enough to engulf the entire planet, so the shadow is always limited to a certain area (see map illustrations below). This area changes during the eclipse because the Moon and Earth are in constant motion: Earth continuously rotates around its axis while it orbits the Sun, and the Moon orbits Earth. Solar eclipses are only visible from within the area where the shadow falls, and the closer you are to the center of the shadow's path, the Annular Means Ring-Shaped The name “annular” comes from the Latin word for ring, “annulus.” These eclipses are named for their darkest, or maximum, point even if it only lasts less than a second. If the characteristic ring of fire is visible from even just one location, the whole eclipse is called an annular solar eclipse. However, in most places and for most of the duration, an annular eclipse looks like a When Do They Happen? Annular solar eclipses can only take place when: • It is • At the same time, the Moon is at (or very near) a lunar node, so the Earth, the Moon, and the Sun are aligned in a straight (or nearly straight) line. • The Moon is near its farthest point from Earth, called 1. Why Not Every New Moon? 2. Close to Lunar Nodes Lunar nodes are the locations where the Moon crosses the Earth's orbital plane. So why isn't there an eclipse every night there is a New Moon? This is because the New Moon also has to be close to a lu...

The following are a number of terms used to describe various aspects of solar eclipses. You’ll find many of them used throughout this website and will encounter others on other sites and in the media as we get closer and closer to the August 21, 2017, solar eclipse across America. Annular eclipse: A solar eclipse where the apparent diameter of the Moon is too small to completely cover the Sun. At mideclipse, the Sun appears as a blindingly bright ring surrounding the Moon. Annularity: The maximum phase of an annular eclipse, when the Moon’s entire disk is seen silhouetted against the Sun. Annularity occurs between second and third contact. It can last from a fraction of a second to a maximum of 12 minutes 30 seconds. Antumbra: The extension of the Moon’s shadow beyond the umbra. Within the antumbra, the Sun appears larger than the Moon, which is visible in silhouette. An observer standing in the antumbra sees an annular eclipse. Baily’s Beads: Caused by shafts of sunlight shining through deep valleys on the lunar limb (edge), they look like a series of brilliant beads popping on and off. They appear just prior to second contact and just after third. They’re named after the English astronomer Francis Baily, who first described them during the annular eclipse of May 15, 1836. Chromosphere: A thin, red-colored layer of solar atmosphere located just above the photosphere. It is briefly visible immediately after second contact and just prior to third. Corona: The Sun’s upper at...

The next 12 months are going to be amazing for solar eclipse fans. People all over North America will be able to check out two different eclipses—one in the western part of North America in October 2023, and the other in the eastern part of the continent in April 2024. Eclipse number one, an annular solar eclipse (i.e., one where the edge of the sun remains visible) will be visible on October 14, 2023 from Oregon to Texas. The second eclipses is total—the entire sun will appear to fizzle out—and will be seen on April 8, 2024 from Mazatlán, Mexico to Newfoundland, Canada. This eclipse’s path will take it over a much more densely populated part of the continent that includes Dallas, Montreal, and Indianapolis. About 31.6 million people live within the path of totality of eclipse number two, and over half the US population lives within 250 miles of it. Lucky people in San Antonio and the surrounding area live at the point where the two lines meet, and they’ll be able to see both eclipses without any travel. Cool places to see the solar eclipses If you’re planning a trip to see either eclipse, book your rooms now: Astronomy fans are organized people, so I presume prime viewing spots are either filled already or filling up fast. Speaking of optimum locations to view a solar eclipse, below are some ideas for sky-watching destinations. See the eclipse at a national park The October eclipse passes over a number of National Parks that make great places to see a solar event. Crater ...

The following list is a guide of things to look for before, during, and after a total eclipse of the Sun. In several cases you’ll be conflicted. For instance, you can’t block the crescent Sun with your thumb to spy the corona before totality starts and simultaneously watch the approaching lunar shadow. But if you’ve never experienced a total solar eclipse, this list will help you know what to expect, and when. Of course, much of what's described below won't apply if you're outside the path of the Moon's dark umbral shadow; in that case, you will see only a partial eclipse — which is why you should make every effort, if possible, to get yourself into the path of totality on April 8, 2024. First Contact: The Eclipse Begins The Moon touches the Sun and takes its first tiny nibble out of the solar disk. First contact is initially visible through a telescope, then in binoculars, and finally with the unaided eye. Regardless of how you view it, observing with a The Vanishing Sun During the next hour or so, the Moon hides more and more of the Sun and daylight fades, though imperceptibly at first. It’s a leisurely affair, so you have plenty of time to look around. As the eclipse progresses, can you detect any change in the color and quality of the sky, the clouds, nearby objects, and distant landscapes? Changing Light Once more than three-quarters of the Sun is covered, the light begins to fade noticeably. By about 15 minutes prior to totality, the light becomes noticeably dimmer a...
