Total Solar Eclipse 2017 in Oregon

Solar Eclipse Oregon




The world’s greatest natural phenomena, the solar eclipse is coming to the United States on August 21, 2017, creating a 90-mile wide total pathway in Oregon before sweeping to Idaho, Idaho, Missouri, Indiana, Ohio, New York, Vermont, and Maine. The next total solar eclipse will hit North America through states of Texas, Arkansas, Missouri, Illinois, Kentucky, Indiana, Ohio, New York, and Vermont on April 8, 2024.

What is a Solar Eclipse?

There are occurrences when the Earth passes through the Moon's shadow. Solar eclipses occur during a New Moon only when the Moon moves between the Earth and Sun disk. When it happens, a shadow is cast over the Earth in what we know as the eclipse of the Sun. There are two types of shadows namely: umbra and penumbra.

Umbra is the dark inner core of the Moon’s shadow that is long enough to hit the Earth. Penumbra is a partial shadow when the Sun is partly blocked. People standing inside of Moon's umbra see a total eclipse while those who see a partial eclipse are in the penumbra. Total solar eclipses last at most 7.5 minutes.

There are three types of solar eclipses depending on how the Moon’s shadow hits the Earth.

A total solar eclipse occurs when the Moon, Earth, and Sun moves in a direct line and the Moon completely covers the Sun, turning daylight into darkness; it is only visible from a small area by people who are in the center or nearby the Moon’s shadow path (umbra). Total eclipses occur approximately once every 18 months but they are visible from less than a half percent of the Earth's surface. However, for any given location, total solar eclipses are rare and occur once every 360 years (on average): some places would experience two total solar eclipses during a decade but others would not see them for 1,000 years.

Partial solar eclipses take place when the Sun, Moon, and Earth are not perfectly aligned. They happen more often than total or annular. Partial solar eclipses are seen during total or annular solar eclipses as well when observers are inside Moon's penumbra (outer shade) or outside its umbra (inner shade). The Sun has a crescent shape that looks like the Moon take a bite out of the Sun

During annular solar eclipses, the Moon is so far from the Sun to completely cover the Sun disk. Instead of blocking the entire view of the Sun, it looks like a dark disk surrounded by a ring of sunlight, or "ring of the fire"; moon's umbra doesn't touch the Earth.

Solar Eclipse 2017 in Oregon

People in Oregon are anxiously anticipating this rare experience. This is a special occurrence as the Oregon Coast, between Lincoln City and Newport will be the first spots the moon’s shadow hits at 10:15 a.m. Pacific Time (PT) on August 21, 2017. The solar eclipse will leave Oregon crossing the Idaho border at 11.27 a.m. Mountain Time (10.27 a.m. PT). The Moon's shadow will take only 12 minutes to travel across Oregon. Total solar eclipse or complete darkness will last about 2 minutes in the center of the shadow's path.

There is a lot of excitement, especially in cities around Oregon that are right in the center of the eclipse. The partial eclipse will start at 9.05 a.m. and end at 11.30 a.m.

A similar solar eclipse occurred in Oregon in 1860, 1918, and 1979. This is a rare opportunity to see science in action on August 21, 2017. According to NASA analyses, the next total solar eclipse in Oregon is only to be expected in 2169.

Protect yourself when viewing the Sun

Before scouting for the perfect spot to view a solar eclipse, understand the need for safety.

The first rule when looking at the Sun is to wear protective eyewear. Looking directly at the sun is so dangerous, you could go temporarily blind in a second. There are several myths about how to view a solar eclipse but some things you should never try when watching a solar eclipse. Never try looking at the sun using CDs, smoked glass, sunglasses, medical x-ray film with images, and color film. All these items allow UV-light to pass through.

To prevent total damage of the retina you must have sunglasses with excellent UV protection. Apart from glasses, there are other ways to view a solar eclipse including:

Welder’s goggles rated 14 or higher are deemed as safe by NASA but note that ratings might differ according to your region.

Eclipse glasses are specially manufactured for eclipses viewing.

Solar filters - These are tricky to use but can be useful for the experienced hand. Make sure to choose an eclipse solar filter that won’t crack under the focused intensity of the sun. Caution must be taken not to break the filters as it takes a second to fully damage the retina.

Eclipse glasses are specially manufactured for eclipses viewing. They filter out 100% of harmful ultra-violet, 100% of harmful infrared, and 99.999% of intense visible light.

  1. don’t understand how the shadow moves from west to east when the sun and moon both move east to west……..

  2. The Moon and the Earth move from the west to the east. The moon velocity is higher than the Earth’s rotation. Therefore, the Moon’s shadow will travel eastward.
