Annular Solar Eclipse over Colorado on October 14, 2023 

An annular solar eclipse visits the southwest corner of Colorado. If you are inside the path of annular solar eclipse, you will see the dramatic sight of the Sun as a thin ring, almost but not completely eclipsed by the Moon. Daylight will be dimmed considerably, but not dark like a total solar eclipse. This eerie sight can be enjoyed with eclipse glasses and other safe viewing methods.

The southwest corner of Colorado inside the path of the annular solar eclipse boasts three units of the National Park system. These are Mesa Verde National Park, Canyon of the Ancients National Monument, and Yucca House National Monument. The sovereign nation of the Ute Mountain Ute tribe offers guided tours of historic sites in the Ute Mountain Tribal Park.

The annular solar eclipse begins in Colorado at 10:30 am MDT with the speed of the Moon’s shadow being 3007 mph. The annular solar eclipse leaves Colorado at 10:35 am MDT and the Moon’s shadow diminishes to 2623 mph. The maximum duration of annularity in Colorado is 4 minutes and 30 seconds.

About the Annular Solar Eclipse

During an annular solar eclipse, the apparent size of the Moon’s disk is slightly smaller than the apparent size of the Sun’s disk. Therefore, only the outer edge of the Sun remains visible and the Sun appears as a brilliant ring if you are inside the path of annular solar eclipse. This is an otherworldly sight often called a “ring of fire”. Here are instructions for the safely viewing solar eclipses by the American Astronomical Society and endorsed by several professional societies.

This eclipse will be a warm-up act for the spectacle of the total solar eclipse crossing the United States just 177 days later on April 8, 2024. While not as dramatic as a total solar eclipse, an annular solar eclipse promises a spectacular vision featuring the striking sight of the Sun as a ring. We recommend solar binoculars for viewing the dynamic Baily’s Beads, sparkling points of brilliant sunlight as the Moon’s limb rolls over the Sun’s edge.

Tips for viewing the annular solar eclipse

• Learn the simple methods to safely view a solar eclipse. At all times during an annular solar eclipse, you must use eclipse glasses or other safe viewing method. Visit eclipse.aas.org/eye-safety for detailed instructions.

• Plan ahead. If you choose to stay in a hotel, be aware that most will sell out. A perfect guide to planning your eclipse is our field guide, greatamericaneclipse.com/books/field-guide-to-the-2023-and-2024-solar-eclipses.

• Get to your destination early and try to spend eclipse night at or near your viewing location. Expect the highways and freeways to be extra busy in the aftermath of totality.

• Be self-sufficient. Fill up your gas tank and bring food and water.

• Check the local TV weather reports as eclipse day approaches. The meteorologists will give you great advice on viewing the eclipse and whether you may need to relocate. We recommend eclipsophile.com as the essential site for eclipse meteorology.

• Unless you are an experienced photographer, we recommend that you not attempt photography during the eclipse. You will be so stunned that it will be difficult to operate a camera. If you choose to do photography, visit Fred Espenak’s MrEclipse.com for advice.

Eclipse weather in Colorado

The essential eclipse weather website eclipsophile.com says that the weather prospects in this region “Cloud cover in New Mexico and surrounding states comes mostly from cold fronts that sweep southward from the Great Plains and the Colorado mountains. They bring heavy cloudiness for the most part, but seldom cover the whole of the track while passing through Arizona and New Mexico. Since fronts are usually well forecast several days ahead, mobility will be a game-saving advantage.”

Our advice is to stack your odds by paying attention to short-term weather forecasts and if poor weather is forecast, jump in your car very early on eclipse day (or the evening before) and drive either to the northwest or southeast to chase after clear skies. You will never regret the effort to seek out a clear view of an annular eclipse of the Sun, it will register in your memory all your life.
