Having a solar eclipse reminds me of the global warming craze. For the global warming crowd to have any credibility with me they have be right with their predictions every now and then. I mean, Algore has told us, how many times, "We only have 10 years left..."?
By predicting there will be a solar eclipse on 10 June, 2021, and when that comes true, it demonstrates a real understanding of the orbital systems.
If the global warming crowd could correctly predict a hurricane on say, August 14th, 2021, will make landfall in Brevard County, Florida, and if that comes true, that too would demonstrate a real understanding of the climate system. But the global warming crowd can't do that, not even close. They have no real understanding of the climate system and therefore I just don't believe them when they tell me the earth is going to end in 10 years or whatever.
Global warming supporters say, "Follow the science". But remember, these are the same people who tell us there are 50 different sexes and a fetus is just a tissue blob.
One of the coolest ways to observe and photograph occurs in the partial phase. Find a place where sunlight passes trough tree leaves, producing dapple patterns on a wall or sidewalk.
As the eclipse progresses, should will see multiple images of the crescent sun. No special equipment nor eye protection is needed, as you are not facing the sun.
You can produce a single crescent image by putting a pinhole in a piece of foil or dark paper. The smaller the hole, the more perfect the image, though it is not as bright. You will have made a camera obscura, a primitive lens. It’s a fun and safe project for kids.
Personally, I like the effect through the trees best.
Whatever you do, use protection if you are facing the sun. Sunglasses are not enough. The filtering needed is like in an arc-welding helmet.
