How to Share the WONDER
And not the DREAD
"To witness a total eclipse of the Sun is a privilege that comes to but few people. Once seen, however, it is a phenomenon never to be forgotten. The black body of the Moon standing out... in sinister relief between Sun and Earth, the sudden outflashing glory and radiance of the pearly corona which can be seen at no other time, the scarlet prominences rising from the surface of the hidden Sun to heights of many thousand miles, the unaccustomed presence of the brighter stars and planets in the daytime, the darkness of twilight and the unusual chill in the air. There is something in it all that affects even the strongest nerves and it is almost with a sigh of relief that we hail the return of the friendly Sun." Isabel M. Lewis, 1924 A Handbook of Solar Eclipses
The Heart of Leo Leo as depicted in Urania's Mirror, a set of constellation cards published in London c.1825.
"A row of lucid points, like a string of bright beads...suddenly formed." ~Francis Baily describing how the moon's topography allows beads of sunlight to shine through in some places, and not in others during a total solar eclipse. We now call these Baily's Beads.
"As a singular event of national scale, and with a global audience - because so many people will be coming from elsewhere, this will rival the moon landing of 1969 as a landmark event for a new generation to come." ~Lika Guhathakurta - NASA Heliophysicist speaking on the upcoming 2017 Great American Solar Eclipse

Some Things You May Notice: COASTAL LOCATIONS: How does a solar eclipse affect the tide? NASA's Answer it is the alignment of the objects (Earth, Moon, and Sun) that causes the large tides, rather than the eclipse itself. How does a solar eclipse affect the seawater itself? In this Natural Science Article, an international academic journal, we find that, Eclipse induced changes in solar radiation affects the ph value of seawater due to the shorter wavelength radiations received on the surface of the earth. The reduction is around 20% and 40% of the difference between ordinary water and seawater during total and annular eclipses respectively.
WEATHER In this EarthSky Article, it states, solar eclipses can produce measurable weather variations -- they slow the wind down and make it change direction. It also affects the temperature (noticeable drop) DAYLIGHT, In this NASA Archived Eclipse Article states, A total solar eclipse is not noticeable until the Sun is more than 90 percent covered by the Moon. At 99 percent coverage, daytime lighting resembles local twilight. Picture courtesy of Marvin Nauman
