Dear Yale Community,
On Monday, August 21 at 11:46 a.m., a total solar eclipse will be visible in Colorado. This event is being called “The Great American Solar Eclipse,” because it is the first time since 1918 that a solar eclipse will be viewable on a path across the entire continental United States.
Since our lunch times coincide with the time of the eclipse, we will be having indoor recess on the day of the eclipse as an additional safety measure. We are also asking our staff to take precautionary measures if they plan to involve their students in this amazing experience to ensure the safety of all involved. Students will be instructed not to look at the partially or even fully eclipsed sun with the naked eye. Additionally, homemade filters or ordinary sunglasses—even very dark ones—are not safe for looking at the sun.
For viewing, all students and staff will be required to use special eclipse-viewing safety glasses. These glasses must meet the standard for ISO 12312-2, which certifies that they reduce visible sunlight to safe levels, and block solar UV and IR radiation. Some individual teachers have elected to provide their students with these glasses.
If you wish to purchase glasses for your student, a list of suggested manufacturers and authorized dealers may be found through the link below. Please note, many items are quickly selling out and/or are sold in bulk. However, we wanted to pass this link on to our parents, in the event you are searching for solar eclipse safety glasses for your child. There are also reports of counterfeit or fake glasses, so please be aware of that. https://eclipse.aas.org/resources/solar-filters
