August 1: The sun is 100 times bigger than Earth. Earth is ___ times bigger than the Moon.
ANSWER: 4! Even though the Sun is 400 times bigger than the Moon, it is also 400 times farther away from Earth than the Moon. That means the Sun and the Moon appear the same size to us here on Earth. That incredible coincidence is why we have total solar eclipses! 
 
August 2: True or False? During a total solar eclipse, bright stars and planets can be seen during the daytime.
ANSWER: TRUE. In fact, constellations that are usually only seen during winter nights will be seen during a summer afternoon!
 
August 3: What is the halo of plasma that surrounds the Sun during totality called?
ANSWER: Solar Corona. You see the faint corona during the eclipse. The Sun's light is too bright to see the corona, so it can only be seen during an eclipse.
 
August 4: How often do total solar eclipses happen worldwide?
ANSWER: 18 months on average.
 
August 5: What is the name of the shadow in which the Moon blocks the entire Sun?
ANSWER: Umbral.
 
August 6: What type of eclipse do you see under a penumbral shadow?
ANSWER: Partial eclipse. In fact, the entire continent of North America will see a partial eclipse!
 
August 7: How long does a total solar eclipse event last?
ANSWER: From the beginning of the partial eclipse, through ~2.5 minutes of totality, and the end of the partial eclipse it will take two-and-a-half to three hours. You can see timing for your location HERE.
 
August 8: Will AM, FM, or HAM radio waves be affected by the eclipse?
ANSWER: AM & HAM. During a total solar eclipse you may be able to access radio signals from hundreds of miles away. One report from the 1970 eclipse suggests a person in North Carolina was able to hear WABC from New York during 96% totality over NYC. 
 
August 9: What percent of the Earth’s surface typically sees a given total solar eclipse?
ANSWER: 0.3%. Out of the 197-million square surface area miles on Earth, only 591,000 square miles will be in totality. 
 
August 10: On average, a total eclipse is visible from any one given spot on Earth about once every ____ years.
ANSWER: 375. That’s why it’s once in a lifetime—or multiple!
 
August 11: During an eclipse, will flowers burn, die, or close?
ANSWER: Close up. Plants that usually close during nighttime may close during totality. Animals may also react as if it is nighttime. 
 
August 12: True or False? The total solar eclipse will affect mid-Missouri weather.
ANSWER: True. As the Sun is half-covered by the moon you will start to feel the temperature drop. It may drop more than a dozen degrees through totality!
 
August 13: As totality ends, what is the brilliant burst of sunlight that appears along the edge of the Sun called?
ANSWER: Diamonds Ring Effect. The corona and the sunburst look like a celestial engagement ring.
 
August 14: In ancient times, in China, what would they do during an eclipse?
ANSWER: They shot flaming arrows at the Sun in an attempt light it back on fire.
 
August 15: True or False? Total solar eclipses have stopped wars.
ANSWER: In Turkey, 585 BC, Lydians and Medes made peace, thinking the eclipse was a sign to lay down their weapons and make peace.
 
August 16:  When was the last total solar eclipse in the lower 48?
ANSWER: 1979. Totality only passed through a small area in the western U.S. on Monday, February 26. Many in America saw a partial solar eclipse.
 
August 17: True or false? A total solar eclipse inadvertently divided Europe into FRA, GER, ITA.
ANSWER: True. Emperor Louis of Bavaria witnessed a total solar eclipse on May 5, 840. He was so terrified by the event he died shortly thereafter. A quarrel between his three sons over Louis’ succession led to the Treaty of Verdun, dividing Europe into France, Germany, and Italy.
 
August 18: In 90 minutes, how many states will totality cross?
ANSWER: 12. From Oregon to South Carolina.
 
August 19: On average, what is the speed of the Moon’s shadow as it crosses the U.S.? 
ANSWER: Around 1,500 mph! Three times faster than a Supersonic jet plane.
August 20: What are intense eclipse fans known as?
ANSWER: Umbraphiles. Remember, the name of the totality shadow is Umbra.
