Total Solar Eclipse – August 21, 2017
On August 21, 2017, the moon will pass between the earth and the sun, causing the day to turn dark. This will not happen again in the United States until 2024! It’s fun to experience a solar eclipse, but we have to be careful. The sun’s rays can cause blindness in adults and children. And while sunglasses won’t protect eyes during an eclipse, keeping your back to the sun and using this viewing box is a safe way to watch how the moon moves to block the sun, creating a crescent shape. Never look directly at the sun!
To help you safely view the solar eclipse, you can make and use this simple “viewing box”. Download the template »
Homemade filters or ordinary sunglasses, even very dark ones, are not safe for looking at the sun; they transmit thousands of times too much sunlight. Refer to the American Astronomical Society (AAS) https://eclipse.aas.org/resources/solar-filters page for a list of manufacturers and authorized dealers of eclipse glasses and handheld solar viewers verified to be compliant with the ISO 12312-2 international safety standard for such products.
