'Crescent Sun Over Tucson' Solar Eclipse Viewing Party

Sunday, May 20, 2012 - 3:00pm to 7:30pm
Sunday's eclipse will be an "annular" eclipse, meaning the moon's apparent diameter will be smaller than that of the sun, so when the moon moves in front of the sun it will block most but not all of the sun's light. This creates an "annulus," or ring, of light around the moon, which appears as a dark disk.

Flandrau Science Center will host the "Crescent Sun" viewing party for the annular solar eclipse on May 20 – join the best way to experience this amazing natural phenomenon. UA astronomy experts and students will be on hand to answer questions and lead telescope viewings and astronomy-themed family activities.

Flandrau will offer solar viewing glasses for $3.99, which includes free admission to the science center and a special showing of Flandrau's "Dark Side of the Moon" Pink Floyd laser show. Solar viewing glasses are the only way to safely view the eclipse directly. Picnics are welcome, and delicious locally sourced meals and popsicles will be available for purchase from food trucks to complete the festivities.

A solar eclipse occurs when Earth's moon passes between the Earth and the sun, totally or partially obscuring the view of the sun from Earth. An "annular" solar eclipse occurs when the moon's apparent diameter is smaller than the Sun so that it blocks most but not all of the Sun's light, creating an annulus (ring) of light around the moon, which appears as a dark disk.

In Tucson, the eclipse will start around 5:30 p.m., peak at 6:40 p.m. and end around 7:30 p.m. At the peak of the eclipse, the sun will appear as a crescent of light, 86 percent obscured by the moon.
