"See if you can feel the change in temperature as the moon begins to block the sun". The moon casts a shadow on our planet. But neither is necessarily greater than the other; with clear skies, any view of the corona - the sun's pearly-white, ethereal atmosphere - should be spectacular.
"As far as why we at the Keene Amateur Astronomers think this eclipse is so special ... this eclipse will cut diagonally across the entire United States, treating most of us to a partial eclipse, but the rest of us to the awe-inspiring, potentially once-in-a-lifetime event - observing totality!"
The brief period of time when the eclipse is in totality - when the moon completely covers the sun - is the only safe time to view the sun without protection.
During an eclipse, the moon passes in front of the sun and casts a crisp, 70-mile wide shadow across the Earth's surface.
"Over the next hour and a half, the eclipse will cross through Oregon, Idaho, Wyoming, Montana, Nebraska, Iowa, Kansas, Missouri, Illinois, Kentucky, Tennessee, Georgia, and North and SC". It will also pass over tiny slivers of Montana and Iowa. That includes a stretch from Salem, Oregon to Charleston, South Carolina. A team of University of Kentucky students, led by College of Engineering Professor Suzanne Smith, is preparing to launch two high-altitude weather balloons on August 21.

The AAS warns that fake solar eclipse-viewing glasses are being sold ahead of the August 21 event and to be cautious when purchasing them.
It's been nearly 40 years since the last solar eclipse was visible in the United States.
Liberty Science Center: Have questions about the eclipse that you want answered?
It's true, the Richland County solar eclipse glasses are not certified by NASA. The total solar eclipse will cover a majority of the United States, from SC to Oregon. The UK will be witnessing a partial eclipse before the total solar eclipse reached the US. The country's last total solar eclipse stretching from coast to coast, on June 8, 1918, came in over OR and Washington, and made a beeline for Florida. Everyone else will only see a partial solar eclipse. It's pretty much the same in 2020.
Scientists tell us the totality will last two minutes around 1:19 pm, but phases leading up to the totality and afterwards will last a total of almost three hours - from about 11:50 a.m.to 2:44 p.m.
So while your Transitions are the ideal way to protect your eyes from harmful light 364 days of the year, August 21 will require a separate pair of glasses.
