Total Solar Eclipse: Safety Precautions and Viewing Guide
Duration of Totality: The Only Safe Time to Observe the Sun
During a total solar eclipse, the moon completely blocks the sun, casting a shadow over a narrow path on Earth. Despite its captivating beauty, it is crucial to prioritize safety when viewing this celestial event.
Viewing Totality
The only safe time to look directly at the fully eclipsed sun is during totality. This phase occurs when the moon perfectly aligns between the Earth and the sun, completely blocking the sun's bright disc. However, this phase is typically brief, lasting only a few minutes.
Before and After Totality
Before and after totality, it is essential to protect your eyes from the sun's harmful ultraviolet (UV) rays. Never look directly at the sun with the naked eye. Instead, use:
* **Certified solar eclipse glasses** with ISO 12312-2:2015 certification. * **Solar filters** that attach to binoculars or telescopes and meet the same ISO certification. * **Project the sun's image** onto a white surface using indirect viewing methods (e.g., pinhole projectors).Upcoming Total Solar Eclipse
The next opportunity to witness a total solar eclipse in the contiguous United States will occur on April 8, 2024.
