Solar Eclipse Below The Horizon
Due to the considerable eclipse magnitude , observers where the totally eclipsed sun is just below the horizon will have the chance to observe the lunar shadow in the high atmosphere, as well as shortened civil twilight and extended nautical twilight. The darkening of the twilight sky could improve the chances of observing the inner Zodiacal light.
A Total Solar Eclipse Occurs When The Sun Moon And The Earth Are In A Direct Line And People Living At Places Where The Centre Of The Moons Shadow Hits The Earth Would See The Event
The last solar eclipse of the year is set to occur on Saturday and some people in the southern hemisphere of the world would witness the event as a total or partial solar eclipse.
A total solar eclipse occurs when the sun, moon and the earth are in a direct line and people living at places where the centre of the moons shadow hits the earth would see the event.
The sky becomes very dark, as if it were dawn or dusk. Weather permitting, people in the path of a total solar eclipse can see the Suns corona, the outer atmosphere, which is otherwise usually obscured by the bright face of the Sun, the National Aeronautics and Space Administration said.
Where will it be visible ?
Antarctica will be the only place on earth from where the total solar eclipse could be seen.
In some other places, where the sun, moon and the earth are not directly lined up, a partial solar eclipse could be seen. Only a part of the suns surface will appear to have a shadow during this celestial event.
A partial eclipse could be seen in parts of Saint Helena, Namibia, Lesotho, South Africa, South Georgia and Sandwich Islands, Crozet Islands, Falkland Islands, Chile, New Zealand, and Australia, NASA said.
How to watch ?
Countries where the event is not visible directly, including India, can still view the event using NASAs live streaming service.

Last Total Solar Eclipse Abroad
The last time a total solar eclipse crossed Earth was March 9, 2016. The total eclipse traversed parts of Indonesia, including Sumatra, Borneo and Sulawesi, while viewers in Australia and parts of south Asia and east Asia were able to see a partial eclipse, according to NASA.

Coming Soon: An Eclipse Double
People in the United States will have an amazing opportunity to view two very different solar eclipses within six months of each other. First up is an annular eclipse on October 14, 2023, followed by the main event: a total solar eclipse on April 8, 2024.
The Exploratorium has been collaborating with NASA for over 20 years to broadcast stunning imagery of eclipses, and we will continue this partnership to stream these events live as they happen. Stay tuned for more information and updates!
People viewing either eclipse from outside the path of totality or annularity will see a partial eclipse. The annular eclipse, often called a ring of fire eclipse, occurs when the moon passes directly in front of the Sun but appears too small to fully cover it. During a total solar eclipse, the moon completely blocks the Sun, revealing the Suns outer atmosphere, or corona. In 2024, totality will last for up to 4½ minutes!

Similar Eclipses Every 18 Years
Solar eclipses occur in cycles, called eclipse cycles.
One of the most popularly studied eclipse cycles is the Saros cycle, which the ancient Babylonians used to predict lunar eclipses.
The Saros cycle is approximately 6,585.3 days, or around 18 years, 11 days, and 8 hours long, and it occurs due to a combination of three lunar cycles:
- The lunar month: the time it takes from one New Moon to the next.
- The anomalistic month: the time it takes from Moon perigee to perigee, the point of the Moon’s orbit closest to Earth.
- The draconic month: the time it takes from one lunar node to another. Also called the nodical month, it lasts, on average, 27.212220 days .
Two solar eclipses separated by a Saros cycle have certain similarities: they occur at the same lunar node, with the Moon roughly at the same distance from Earth, and they take place around the same time of the year.
The path of totality for the eclipses also looks very similar on a mapwith one important difference. The path of totality is shifted westwards, one-third of the way around the globe. This is due to the fraction 0.3 in the Saros period of 6,585.3 days. During this one third of a day, the Earth spins on its axis, meaning the eclipse takes place further to the west.
Superstitions Surrounding Solar Eclipses
Throughout history, the rarity of solar eclipses and their ability to seemingly turn day to night has meant that they were seen as a bad omen. Ancient cultures believed that eclipses occurred when a demon ate the Sun or Moon. In Ancient Greece, an eclipse meant a god was angry, and the Pomo indigenous people of northern California believed that a bear had bitten the Sun in a fight causing temporary darkness.
Even today, some people believe that solar eclipses can harm pregnant women. Fortunately, the only risk from an eclipse is to your eyes.

Moon Is Far From Earth
Throughout every lunar month, the distance between our planet and the Moon varies because the shape of the Moon’s orbit around Earth is elliptical, rather than circular.
The reason we can see the glowing outer edge of the Sun at the maximum point of an annular eclipse is that it happens while the Moon is near its farthest point from Earth, called apogee, when the Moon is smaller than the Sun when viewed from Earth.
The Moon’s antumbra.
©timeanddate.com
Solar eclipses are caused by the Moon casting shadows on Earth. There are 3 different types of shadow that the New Moon can cast on Earth: the umbra, the penumbra, and the antumbra.
To see annularity, you must be in a location where the Moon casts the antumbra. At the maximum point, the width of the annular path is typically around 150 km although this can vary considerably. If you’re at the center of this zone, you will see the annularity’s maximum point as a perfect ring of fire. In other areas of annularity, where the Moon is not perfectly centered on the Sun, the ring has varying width.
If you’re at the edge of the annularity path, you may see a broken ring of fire andfor a brief momenta phenomenon called Baily’s beads, which are little bead-like blobs of light at the edge of the Moon. These happen because gaps in the mountains and valleys on the Moon’s surface allow sunlight to pass through in some places, but not in others.

In just a few days, on Monday, August 21, a solar eclipse will be visible across America. Some regions will experience the mid-day twilight of totality. Because were far from the path of totality, well see a partial eclipse, the first in this region since December 25, 2000. Around Philadelphia, the moon will cover 79.9% of the sun. With 20% of the suns surface still exposed, a bright, clear sky will dim only slightly, as if very thin clouds are passing through. In fact, if you werent aware an eclipse was occurring, you wouldnt suspect an eclipse was occurring! Even without much sky brightness change, you can still have an awesome, authentic science experience viewing a celestial phenomenon most people have never seen before. Here are five suggestions to maximize your eclipse experience:
Best wishes for clear weather and a great eclipse!
What Eclipse Occurs Every 100 Years
Solar eclipses are fairly numerous, about 2 to 4 per year, but the area on the ground covered by totality is only about 50 miles wide. In any given location on Earth, a total eclipse happens only once every hundred years or so, though for selected locations they can occur as little as a few years apart.

How To Safely Watch A Total Solar Eclipse
It is never safe to look directly into the sun, even if it’s partially obscured. Anyone watching a partial eclipse must wear eclipse glasses at all times if facing the sun, or use an alternate indirect method, NASA says. This also applies during a total eclipse up until the period of totality, when the sun is totally blocked. During that short time, when the moon completely obscures the sun, it is safe to look directly at the star, NASA says, but timing is crucial.

What’s The Meaning Of Blood Moon
Blood moons bring chaos, disruption, and change in astrology. Because they require a full moon and total lunar eclipse to occur, blood moons amplify the already strong powers of the lunar cycle. The full moon symbolizes sudden illumination, hidden information rising to the surface, and shifts in your inner life.

Earth’s Distance To Sun
Earth’s orbit around the Sun is also elliptical, which means that there is 1 point of the path when Earth is at its closest point to the Sun and 1 point when it is furthest away . Earth’s distance to the Sun also sometimes affects the type of eclipse, the duration of the eclipse, exactly how much of the Sun’s disk will be eclipsed, and the size of the area on Earth where the eclipse is visible.
Help Scientists Collect Data During The Eclipse
There are several Citizen Science Projects that will be up and running during the Eclipse. As your watching one of Nature’s Natural Wonders, help science collect some data! Most of these can be handled by using an App, and simple observations. You can find out more by reading this brief web article!
Where will You be for the 2017 Total Solar Eclipse?
A total solar eclipse will occur on Monday, August 21, 2017. The event has been described as the “Great American Eclipse” as it will be visible in totality only within a band across the entire contiguous United States.
A solar eclipse occurs when the Moon passes between Earth and the Sun, thereby totally or partly obscuring the image of the Sun for a viewer on Earth. A total solar eclipse occurs when the Moon’s apparent diameter is larger than the Sun’s, blocking all direct sunlight, turning day into darkness. Totality occurs in a narrow path across Earth’s surface, with the partial solar eclipse visible over a surrounding region thousands of kilometers wide.
The previous time a total solar eclipse was visible across the entire contiguous United States was during the June 8, 1918 eclipse.

What Phase Is The Moon In During A Solar Eclipse
Solar eclipses only take place during a new Moon phase. This is because, from our perspective on Earth, during a solar eclipse the Sun is behind the Moon lighting up the side that we can’t see, leaving the side facing us in darkness.
Not every new Moon coincides with an eclipse, because the Sun, Moon and Earth need to line up in such a way that the Moon’s shadow lands on our planet and this doesn’t always happen. This is because the Moon’s orbit around Earth is slightly inclined compared to Earth’s orbit around the Sun.
If the Moon, Sun and Earth align when the Moon is full, it causes a lunar eclipse. In this case, it is Earth that passes between the Sun and Moon and casts its shadow on the Moon.

What Is An Eclipse Of The Sun By The Earth
Its something that can only be witnessed from spaceand is, at some point, always witnessed by any spacecraft orbiting Earth. It would also be possible to see an eclipse of the Sun by the Earth from the Moon if you stood on the lunar surface during what would, on Earth, look like a lunar eclipse.
The Apollo astronauts of the 1960s and 1970s also reported seeing Earth eclipse the Sun while on the way back from the Moon.
The last total lunar eclipse was on May 15/16. 2022and it looked absolutely spectacular. The next total lunar eclipse will take place on November 8, 2022 with totality lasting a whopping 84 minutes.

Observing A Solar Eclipse Safely
As a solar eclipse approaches, the mainstream media often will provide a variety of warnings and advisories against looking at the sun with bare eyes, as blindness could ensue. This has given most people the idea that eclipses are dangerous.
Not so!
Its the sun that is dangerous all the time! The sun constantly emits invisible infrared rays that can damage your eyes. Ordinarily, we have no reason to gaze at the sun. An eclipse gives us a reason, but we shouldnt.
There are safe ways, however . . .
By far, the safest way to view a solar eclipse is to construct a pinhole camera. A pinhole or small opening is used to form an image of the sun on a screen placed about 3 feet behind the opening. Binoculars or a good telescope mounted on a tripod can also be used to project a magnified image of the sun onto a white card. The farther away from the card, the larger you can focus the image. Look for sunspots. Notice that the sun appears somewhat darker around its limb or edge. This method of solar viewing is safe so long as you remember not to look through the binoculars or telescope when they are pointed toward the sun put another way, never look directly at the sun when any part of its blindingly bright surface is visible.
Solar Eclipse During Totality
Recorded in Lusaka, Zambia, this video shows the wispy solar corona that becomes easier to see when the Moon covers the Sun during a solar eclipse. A solar prominence is also visible on the left side of the Sun. The glowing bump consists of plasma, a hot gas containing electrically charged hydrogen and helium atoms and electrons. Video: Ken Phillips.
Remember that it needs to be a clear day for the best chance of seeing a solar eclipse, since clouds could block the Sun. However, a total eclipse can still be a memorable event even if its cloudy, as you will still experience darkness falling suddenly and animals behaving strangely.
