A total solar eclipse occurs when the Moon’s apparent diameter is larger than the Sun’s, blocking all direct sunlight, turning day into darkness. ~ Wikipedia

While we receive between 4-7 eclipses, both solar and lunar, per calendar year with most years receiving 4 eclipses, total solar eclipses — when the moon is positioned between the sun and earth — happen less often.

The recent total solar eclipse on August 21, has been referred to lately in the press as ‘The Great American Eclipse’ because it was the first time since 1979 that so many states in the US were able to see the phenomena in its entirety.

For some reason, this recent celestial activity gripped all of us in eclipse fever mode. I read articles on the subject by the dozens and got caught up in it. I imagined I’d be the most intrigued by the pictures of the moon crossing the sun, but I ended up being even more gripped by the images friends and acquaintances took in their backyards, of a little-known potential side-effect of the eclipse, called “shadow bands” or “shadow snakes”.

I read a great article, Shadow Snakes Are the Rare Solar Eclipse Mystery Scientists Still Don’t Fully Understand, by Sam Blum (https://www.thrillist.com/news/nation/solar-eclipse-shadow-bands-snakes). The author explains the phenomena as being, ‘snake-like shadow bands, which are as rare as they are visually alluring. While the creepy effect — much like the look of a rippling pond or a swimming pool illuminated by ample sunlight — are a natural byproduct of total solar eclipses, they have long puzzled viewers and scientists alike, according to NASA.

I hadn’t heard of this before and my interest was piqued. Further, Blum said, ‘Shadow bands are so rare that few images of the darting shadows exist.’ Who doesn’t love a mystery?

This was something I wanted to see.

Luckily, I knew I had lots of American friends who would witness the eclipse first-hand and snap pictures and post them. As expected, soon after the total solar eclipse on the 21st of August, a flood of homespun images began to hit the net.

And, to my delight, there were not only images of the crossing orbs above, there were also photographs of the patterns created below.

I consulted the article by Blum again, he explained the fleeting displays only occur in the moments just before totality, or when the moon completely covers the sun, and the moments just after, as the moon starts to get out of the way again.

I thought of all the images I’d seen on Facebook that day, the photos I liked the most in each case were the shadow effects, which I realized in retrospect were this exact “rare phenomena” cited. These were the shadow snakes/bands or in more poetic terms, “moon shadows,” as Debra Powers put it so perfectly.

Lots of people were able to capture the formerly rare effect. I thought the resulting images were delightful.

I also watched the Nasa play-by-play. What a spectacle.

Something about seeing shadow play in the middle of the day made the child inside me leap with joy. I wanted to leap around in the shadows like a wild thing and play cowboys and Indians again. Two minutes later the show was all over. Nature is cool!

Did you get eclipse fever this year? How did it affect you.

Talk to you later.
