Seven Things You Must Anticipate For The 2017 Solar Eclipse
“5.) Prepare for things to get chilly. When 80% of the sunlight is blocked, you won’t notice a difference in brightness, but your skin will. The Sun is so brilliant that the unaided human eye can’t tell the difference even when the Sun is 99% obscured. But sunlight reaching Earth outputs a total of approximately 700 Watts-per-square-meter in the infrared, where human skin is sensitive. By comparison, a fully overcast sky might block only about 65-70% of the heat from the Sun, something your skin will definitely notice. If you’ve never experienced it before, the lack of heat coming from the Sun can feel both surprising and disturbing. Prepare for this the same way you’d prepare for sundown; temperatures may drop by as much as 20-to-30 degrees Fahrenheit in some places over the course of an hour or two.”
On August 21, 2017, the Moon will pass between the Earth and the Sun, casting its shadow onto the Earth’s surface and causing a total solar eclipse. For the first time since 1979, a portion of that eclipse will cross the continental United States, with the path of totality running coast-to-coast and crossing through 14 states. It’s poised to be a record-breaking, breathtaking eclipse in a number of ways. It may turn out to be the most-viewed eclipse in history; it may create the world’s largest traffic jam ever. But it may also be a spectacular sight and experience that the majority of people have never seen. With over 200 million people within a single day’s drive of totality, you can bet that it’s going to be one of the most spectacular events of the entire decade.
