Total Solar Eclipse: Experience and Learning Resources

So what do you need to safely photograph the Aug 21 eclipse? Most cameras, including many found on phones, have adjustable exposures, which can help you darken or lighten your image during the event. The odds of that seem astronomical, pardon the pun.
Due to the earth's spherical shape, the 60- to 70-mile-wide umbra will sprint eastward across a swath from OR to SC at 2,900 miles per hour at the West Coast, slowing to 1,500 miles per hour by the time it reaches the East Coast. "You can often make out sunspots on the surface and since the image is projected onto a screen, your field of view includes the entire sun".
From everything I've read it is worth the trip to travel and see the total eclipse. However, at totality, when the moon completely blocks the sun, make sure to remove the filter so you can see the sun's outer atmosphere - the corona. It's been described as stunning. This extraordinary cosmic spectacle will pass through 13 states, and everyone in the continental US will have the opportunity to see at least a partial eclipse, making it the most widely viewed American eclipse of all time.
Because of the sudden darkness and drop in temperature, it's very possible to witness sudden changes in animals' behavior. Depending on the size of the tree, you could see up to thousands of tiny little crescent-shaped slivers of the sun's shadow on the ground. The partial solar eclipse will begin at 9 a.m., peaking at 10:19 a.m. and conclude at 11:40 a.m.
That's not saying that pets should be kept indoors during the eclipse, but if you plan on sharing the experience with the family's beloved pet, perhaps handing them their own pair of eclipse glasses is the safe way to go. This is why doctors recommend wearing special eclipse glasses, which are created to filter out those harmful rays. It's a long duration event so spread your looks out.
The eclipse in 2024 will have 98% coverage in Louisville. So experience and enjoy the event, but do be careful and monitor the kids closely to keep them safe. "Without ionizing radiation، the ionosphere will relax،going from daytime conditions to nighttime conditions and then back again after the eclipse،" said Marshall. Particles called neutrinos pass through the solid body of the moon during the eclipse and a second later reach Earth and pass through it, too.
