For the first time since 1979, the United States will experience a total solar eclipse on August 21.
Are You a "Twilight" Buff?!
There are usually six or seven total solar eclipses per decade, somewhere in the world.
In less than a fortnight, the moon is going to totally cover the sun. But, here's the rub: it's taking place on August 21. The moon's shadow will create a 70-mile wide path as it moves diagonally across the USA, which is known as the path of totality.
Smith was in college in North Carolina at the time of the 1970 total solar eclipse. Depending on how long you gazed at the sun and how badly the retinal cells were damaged, this spot will either fade away in time or remain permanent.
If you're lucky enough to be in the path of totality, you may notice a change in the sky's hue as the shadow moves closer to you, Young says. "I know of a few universities and trip planners that have been planning on observing the event for five years or more", he said.
If you are the victim of a scam or other unscrupulous business practice related to the eclipse, you can go to BBB.org to open a complaint or report it to BBB Scam Tracker.
The last time this happened, it was February 26, 2017, and it was visible across South America in the morning and Southern Africa at night. When the moon's trajectory overlaps, the sun's position in relation to a given point on Earth, we experience either a partial or total eclipse, a phenomenon that generally takes place over a three-hour period. That is why it is important to use solar filters, or eclipse glasses.
Zelier said millions of Americans will "produce predictable traffic congestion" as the travel to cities along the totality line. The AAS recognizes that bogus pair of solar viewers have been "flooding the market". With these shades, you can view the eclipse before, during, and after totality without any problems. So your regular sunglasses, or sunglasses that your mother got after her cataract surgery, are not going to protect the eyes. In fact, there is a massive difference even between a 99% partial eclipse to a 100% total eclipse.
Yes. You need to use some sort of special protection for your eyes, whether it be eclipse glasses, or shade #14 welder's glass.
You see, smartphone lenses are very small, LG is just now offering an f/1.6 aperture to let more light in, and, in general, they also have filters to restrict some of the light falling on the sensor.
