2023 ANNULAR SOLAR ECLIPSE.

Join us at Custer Observatory for the 2023 Annular Solar Eclipse! Witness the phenomenon of an annular solar eclipse in person through our filtered high-powered, state-of-the-art telescopes and using certified safe solar eclipse viewing glasses (provided). This rare celestial event occurs when the Moon aligns with the Sun, creating a mesmerizing "ring of fire" in the sky along the path of totality. In our area, we will experience a partial solar eclipse with the moon covering approximately 23% of the sun's disk at the peak of the eclipse at approximately 1:22pm. Watch with us as the Moon partially covers the Sun, casting a shadow over the Earth.

Don't miss this opportunity to marvel at the wonders of the universe!

Come back at 7pm as we will be open for our regular Saturday night stargazing.

This is a weather-permitting event. Please bring a blanket or chair to comfortably view the eclipse from our lawn. Certified safe solar viewing glasses will be provided at check-in.

$8 Adult, $5 Children Under 16, $3 Observatory Members. Your donations allow Custer Observatory to continue to offer programs like this to the community and are greatly appreciated.

An annular solar eclipse happens when the Moon passes between the Sun and Earth, but when it is at or near its farthest point from Earth. Because the Moon is farther away from Earth, it appears smaller than the Sun and does not completely cover the Sun. As a result, the Moon appears as a dark disk on top of a larger, bright disk, creating what looks like a ring around the Moon.

A partial solar eclipse happens when the Moon passes between the Sun and Earth but the Sun, Moon, and Earth are not perfectly lined up. Only a part of the Sun will appear to be covered, giving it a crescent shape. During a total or annular solar eclipse, people outside the area covered by the Moon’s inner shadow see a partial solar eclipse.

INTERNATIONAL OBSERVE THE MOON NIGHT 2023.

In cooperation with NASA, Custer Observatory will be participating in this special International Observe the Moon Night event. This is a worldwide celebration of lunar science and exploration held annually since 2010. One day each year, everyone on Earth is invited to observe and learn about the Moon together, and to celebrate the cultural and personal connections we all have with our nearest celestial neighbor. This year's celebration also falls during the peak of the Orionid Meteor Shower which can be viewed with the naked eye. Join us and try to catch a glimpse of one of these spectacular "shooting stars" and learn about our Moon.

If the weather is clear, the Custer Observatory dome and other telescopes on site will be open for viewing and guided by Observatory staff.

$5 Adult, $3 Children Under 16 , Observatory Members FREE. Your donations allow Custer Observatory to continue to offer programs like this to the community and are greatly appreciated.
