Friday (9/29) KNAU in the White Mountains, KNAA 90.7, will reduce power temporarily. This is to protect tower workers as they work on an adjacent cellular antenna. Reception may be poor to non-existent in some areas including service over the repeater on 105.3. Online streaming service will not be affected. With afternoon winds forecast, the crew will likely get an early start and may not require a great deal of time for their work.

Partial Solar Eclipse Visible In Arizona Today

NPS/Erin Whittaker

Every state in America will witness at least a partial solar eclipse today. In Arizona the celestial show starts at about 9:15 this morning and ends at noon. KNAU’s Melissa Sevigny reports.

Arizona isn’t located in the “path of totality” where the moon will completely block the sun.

But a partial eclipse will be visible. Kevin Schindler of Flagstaff’s Lowell Observatory says the moon will cover about 70 percent of the sun at 10:30 a.m., leaving a blinding crescent.

"We have solar eclipses just by chance," he explains, "because the sun is 400 times larger than the moon, but it’s also 400 times further away. The sun and moon appear to be the same size in the sky, which allows the moon to cover the sun."

Schindler says the last time a solar eclipse was visible coast-to-coast was nearly a century ago.

It’s never safe to look directly at the sun during a partial eclipse. But you can wear solar-filtered glasses or poke a hole in a piece of paper to create a ‘pinhole camera.’  When held up to the light it will project a tiny image of the crescent sun.

Astronomers are on hand at Lowell Observatory this morning with solar telescopes. Solar glasses are also available at many public libraries around the state. Click here for a map of participating libraries.

Melissa joined KNAU's team in 2015 to report on science, health, and the environment. Her work has appeared nationally on NPR and been featured on Science Friday. She grew up in Tucson, Arizona, where she fell in love with the ecology and geology of the Sonoran desert.
