Solar Eclipse Facts

A total solar eclipse is a rare event in any given location, occurring roughly once every 375 years.

During a total solar eclipse, the moon's shadow travels across the Earth's surface at speeds up to 2,000 miles per hour.

Baily's Beads Effect

Just before totality, dazzling spots of light appear around the moon's edges due to sunlight streaming through lunar valleys.

Solar Corona Visibility

Only during a total solar eclipse can you directly observe the sun's corona, its outer atmosphere, shining in ethereal light.

Temperature Drop

During totality, temperatures can drop by 20 degrees Fahrenheit or more, creating a noticeable chill.

Risk of Solar Retinopathy

Only during a total solar eclipse can you directly observe the sun's corona, its outer atmosphere, shining in ethereal light.

ISO-Certified Eclipse Glasses

For safe viewing, use eclipse glasses that meet the ISO 12312-2 international standard, which block out harmful solar radiation.

No Ordinary Sunglasses

Regular sunglasses, even very dark ones, are not safe for looking at the sun because they don't block enough solar radiation.

Pinhole Projectors

An alternative to glasses, pinhole projectors allow you to view the eclipse indirectly by projecting an image of the sun onto a surface.

Camera, Telescope, and Binocular Warning

Never look at the sun through an unfiltered camera, telescope, or binoculars, as they can concentrate solar rays and cause severe eye injury.

Orbital Mechanics

Solar eclipses occur when the moon passes between the Earth and the sun, casting a shadow on the Earth.

Pre-Eclipse Eye Check

Encourage an eye health check-up before the eclipse to ensure your eyes are in top condition for viewing.

Post-Eclipse Eye Care

Advise on monitoring for symptoms of solar retinopathy, such as blurred vision or a blind spot, and seeking immediate ophthalmological care if symptoms occur.

Solar Corona Visibility

Highlight the importance of regular eye exams for maintaining overall eye health and catching potential issues early.

Animal Behavior

Animals often react to the sudden darkness of totality with behaviors typical of nightfall, such as birds returning to nests.

Shadow Bands

Just before and after totality, wavy lines of alternating light and dark can be seen on the ground and walls, caused by atmospheric turbulence.

Diamond Ring Effect

Just before totality, dazzling spots of light appear around the moon's edges due to sunlight streaming through lunar valleys.

360-Degree Sunset

During totality, the horizon glows with the colors of sunset all around you, a surreal and unique experience.

Protect Your Vision

Emphasize the importance of using ISO-certified eclipse glasses or other safe viewing methods to protect against harmful UV rays.

Understand the Risks

Educate on the dangers of looking directly at the sun without proper protection, including during a solar eclipse.
