How To Safely Watch The solar Eclipse: You may be ready to welcome the Total Solar Eclipse of August 21, 2017, but do you already know how the solar eclipse is going?
The event of a solar eclipse is a rare event and attracts a lot of public attention to watch it, many of them make mistakes in observing this solar eclipse because it is not in accordance with its safety that can cause temporary eye damage and could be more than that if it can cause severe blindness.
Before discussing how to safely see the solar eclipse let me discuss a little about the pase of solar eclipse.

If you want to see the eclipse of the Sun, you must be in the shadow path of the Moon, which has 3 different parts. The first part is umbra. Umbra is the darkest shadow of the 3 parts of the Moon's shadow. The Earth's territory through which the umbra shadow path will see the total eclipse. At that time, the Sun disk was completely covered by the Moon disk.
The second part is penumbra. Penumbra is the outer Moon's shadow. The area through the penumbra path will see a partial solar eclipse (partial), and the sky will not be as dark as the total solar eclipse.
And the third part is antumbra. Antumbra is Antumbra is a region in the shadow of a solar eclipse where the Moon that covers is fully visible in the disc of the light source (sun). An observer residing in the antumbra area will fully see the eclipse event of the ring. The word Antumbra comes from the Latin word ante meaning "before" and umbra meaning "shadow".
The second, partial eclipse, occurs when the Moon disk (at the peak of the eclipse) only partially closes from the Sun disk. In this eclipse, there is always a part of the solar disk that is not covered by the Moon disk.
The third, the eclipse of the ring, occurs when the Moon disk (at the peak of the eclipse) only partially closes from the Sun disk. This type of eclipse occurs when the size of the Moon disk is smaller than the solar disk. So when the Moon disc is in front of the Sun disk, not all of the Sun's disks will be covered by the Moon disk. The portion of the Sun's disk, which is not covered by the Moon's disk, is around the Moon disk and looks like a luminous ring.
The fourth, a hybrid eclipse, an eclipse phenomenon that shifts between a total eclipse and a ring. At a certain point on Earth's surface, this eclipse appears as a total eclipse, whereas at other points it appears as a ring eclipse. Eclipse hybrids are relatively rare and rare.
Although it only happens during the New Moon phase, unfortunately, the solar eclipse does not occur every calendar month. This is because the orbital plane of the Moon around the Earth tends to tilt at an angle of 5 ° to the Earth's orbital plane around the Sun (ecliptic).
That way there is a time when the Sun-Moon-Earth is aligned straight, but the Moon's position is too up or down from Earth's orbit (due to 5 ° tilt). So that at these times, the Moon and the Sun are not always a straight line in the New Moon phase.
Below is the path of the eclipse during an eclipse in the United States.
America got a total solar eclipse in 1979, in Hawaii in 1991, followed by 2017, and later it will happen again in 2024.
Below is a video announced by Nasa in 2015. The confirmed total solar eclipse in America on August 21, 2017, based on local time
An Alaska Airlines plane flies when the eclipse departs from Portland at 7:30 local time, and flies to the city of Oregon. When the eclipse occurs later the plane's flight is at an altitude of 35 thousand feet, and passengers can enjoy the eclipse. Because the route of this aircraft is unique and the company will make sure to see the eclipse above the plane without weather constrained.
Other aircraft routes in the Pacific Northwest area also crossed the eclipse area, with the goal of Redmond, Oregon, and Sun Valley, Idaho.

Solar eclipse glasses have been designed specifically for the observation of solar eclipses because the filter content has been adjusted & safe for the observation of the sun. So observing the eclipse in this way is the most secure & practical. These glasses will usually be sold a lot before the solar eclipse occurs or can be ordered to shop astronomy. Prohibited for those of you who try to use filters on film negatives, floppy disks, or CD-ROM pieces in the observation of a solar eclipse. Although sunlight can be dim but infrared light, UV from the sun can penetrate this media, because the sun's hidden rays are harmful to our eyes as well.
2. Laser Glass No.14
Welding glasses number 14 is the second safest way to observe the solar eclipse because these glasses are very dark perfectly suited and safe to use for the observation of solar eclipses, because the glare from the sun can be reduced by using welding glasses number 14 this.
3. Pinhole Camera

This method is a method of observing the solar eclipse without looking directly toward the sun, which is only seen through the projection of light that penetrates only small holes. This method is easy to do by piercing a piece of paper that is not thick can be cardboard, cardboard, etc. Just hunt small and small do not be too big if it is projected into the sunlight when the eclipse occurs and see shadow projection of solar eclipse.
Here's another method of pinhole camera that we can make observation tools from materials/media that are easy to get such as tree shadows, biscuit holes, kitchen utensils, even our hands can be used as a pinhole camera projection.
4. Live Streaming on Television / Web Astronomy
If you are complicated with the above tools you can watch the solar eclipse through live streaming on television or web astronomy. Take it easy there must be live broadcast live a solar eclipse during the event or can visit live streaming web at LIVE CNN. This observation is much safer than experimenting with a less secure device for observing a solar eclipse simply viewing a solar eclipse broadcast alone on television or web streaming.

Phase Occurrence of Solar Eclipse
The solar eclipse occurs when the position of the Moon lies between the Earth and the Sun, thus closing some or all of the sun's light. Although the Moon is smaller, the Moon's shadow is able to protect the sun's light completely because of the Moon, an average distance of 384,400 kilometers from Earth, is closer than the Sun with an average distance of 149,680,000 kilometers.

An observer residing in the antumbra area will fully see the eclipse event of the ring. The word Antumbra comes from the Latin word ante meaning "before" and umbra meaning "shadow".
The types of solar eclipses
The solar eclipse can be divided into four types. The first, the total eclipse, occurs when during the peak of the eclipse, the solar disk is completely closed by the Moon disk. At that time, the Moon disk was as big or bigger than the Sun disk. The size of the disc of the Sun and the moon disk itself varies depending on each Earth-Moon and Earth-Sun distance.The second, partial eclipse, occurs when the Moon disk (at the peak of the eclipse) only partially closes from the Sun disk. In this eclipse, there is always a part of the solar disk that is not covered by the Moon disk.
The third, the eclipse of the ring, occurs when the Moon disk (at the peak of the eclipse) only partially closes from the Sun disk. This type of eclipse occurs when the size of the Moon disk is smaller than the solar disk. So when the Moon disc is in front of the Sun disk, not all of the Sun's disks will be covered by the Moon disk. The portion of the Sun's disk, which is not covered by the Moon's disk, is around the Moon disk and looks like a luminous ring.
The fourth, a hybrid eclipse, an eclipse phenomenon that shifts between a total eclipse and a ring. At a certain point on Earth's surface, this eclipse appears as a total eclipse, whereas at other points it appears as a ring eclipse. Eclipse hybrids are relatively rare and rare.
Only When in New Moon Phase
In order for a solar eclipse to take place, the Sun, Moon, and Earth must align in a perfectly straight line, a position called astronomers as Syzygy. Positions like this can only happen in the New Moon phase aka New Moon.Although it only happens during the New Moon phase, unfortunately, the solar eclipse does not occur every calendar month. This is because the orbital plane of the Moon around the Earth tends to tilt at an angle of 5 ° to the Earth's orbital plane around the Sun (ecliptic).
That way there is a time when the Sun-Moon-Earth is aligned straight, but the Moon's position is too up or down from Earth's orbit (due to 5 ° tilt). So that at these times, the Moon and the Sun are not always a straight line in the New Moon phase.
When It's Time to see a solar eclipse
Total solar eclipse 21 August 2017 in the United States: The 2017 solar eclipse in the American land area. From Oregon to South Carolina along 113 km. This time the American people get a fairly long solar eclipse, crossing from the West to the East. The area will get a total darkness when the sunlight is blocked by the moon. The eclipse starts at 9 am PDT in Madras to Columbia from 1 pm.Below is the path of the eclipse during an eclipse in the United States.
