It’s Happening August 21: Edgewater Eclipse Watch

, , , , , , , , , , ,

The Cuyahoga Astronomical Association (CAA), in cooperation with Cleveland Metroparks, will host an Eclipse Watch event at Edgewater Park, on Cleveland’s western Lake Erie shore, from 12:30 to 4:00 PM, Monday, August 21. The event will be free and open to the public, no reservations required, to observe the day’s solar eclipse. In case of rain, the event will be canceled.

The Edgewater Eclipse Watch will include:

  • Telescopes equipped to safely view the eclipse, tended by CAA members
  • Eclipse viewing glasses provided by AstroZap, one per group, please!)
  • Non-profit organizations, including Cleveland Metroparks, with family activities.
  • Additional activities to be announced!

The venue for the Edgewater Eclipse Watch will be at the west end of Edgewater Park’s lower level parking lot (see map below). Telescopes and other activities will be in the grassy area adjacent to the parking lot. Visitors may come and go as they please during the event.

Millions of people will enjoy this eclipse of the Sun, some portion of which will be visible from everywhere in the continental United States; it’s even been dubbed “The Great American Eclipse” and “The National Eclipse.” Locations along a relatively narrow strip of land stretching from Oregon and the Pacific Northwest to the Atlantic off South Carolina will enjoy the full glory of a total solar eclipse. Here in Northeastern Ohio, we will see a deep partial eclipse with, at its peak, the Sun reduced to a brilliant crescent in our early afternoon sky.

CRITICAL: Vision safety is a major concern: It is important to note: even during the maximum point of our partial eclipse it is not safe to look at the Sun without proper vision protection. According to a statement from NASA, “The only safe way to look directly at the uneclipsed or partially eclipsed Sun is through special-purpose solar filters, such as ‘eclipse glasses’ or hand-held solar viewers. Homemade filters or ordinary sunglasses, even very dark ones, are not safe for looking at the sun.” Here’s a quick video about how to safely view the eclipse via WKYC and our own Jay Reynolds.

A solar eclipse takes place when our Moon comes between Sun and Earth casting its shadow on Earth’s surface. The illustration below shows how the depth of Moon’s shadow varies depending upon how much of Sun is covered. The small black dot indicates the area where all of the solar disk is covered and where a total solar eclipse is in progress; outside of that dot, a large shaded area shows where various levels of partial coverage — the partial eclipse — is visible.

This video from NASA shows how eclipses work and why they don’t happen every month. Spoiler: Moon’s shadow “misses” the Earth most of the time…
