Annular solar eclipse of October 14, 2023
Eleven years after an annular solar eclipse crossed the western United States on May 20, 2012, another annular eclipse will race across the USA from Oregon to Texas on Saturday, October 14, 2023. The path of the annular solar eclipse next visits Central America and South America, and ends shortly after at sunset in the Atlantic Ocean. In the USA, the annular solar eclipse begins in Oregon at 9:13 a.m. PDT and ends in Texas at 12:03 p.m. CDT.
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”, but you must use eclipse glasses, solar filters, or other safe viewing method during all stages of eclipse. Here are instructions for the safely viewing solar eclipses by the American Astronomical Society and several professional organizations.
This eclipse will be an appetizer for the spectacle of a 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.

The annular solar eclipse across North America, Central America, and South America
These three maps provide an overview of the eclipse across the Americas. The region where the Moon will slide within the disk of the Sun is the orange band labeled the path of annular solar eclipse. Outside the path is shown the maximum degree of obscuration, simulated at maximum eclipse by the partial eclipse figures. All of North America, except for northwest Alaska, will experience at least a partial solar eclipse. Most of South America, except for southern Chile and Argentina, will also experience at least a partial solar eclipse.

The path of annular solar eclipse over Oregon, California, and Nevada
The annular solar eclipse first touches the United States at 9:13 a.m. PDT at Reedsport, Oregon. The shadow of the Moon at this point is screaming at 7,534 miles per hour. The maximum duration of annularity at the Oregon coast is 4 minutes, 29 seconds and the eclipse is 13 degrees high in the sky.
The path of annular solar eclipse over Utah, Arizona, Colorado, and New Mexico
The eclipse passes over the Four Corners region and many national parks and national monuments will be prime viewing locations. The weather prospects are good in this area and an eclipse trip can be combined with a vacation to some of the many scenic parks in the American Southwest. Several distinctive viewing locations are through an arch at National Bridges National Monument, from the crimson hoodoos at Bryce Canyon National Park, framed by the pre-Columbian structures at Chaco Canyon, and in scenes from the ranch country around Roswell, New Mexico.
The path of annular solar eclipse over Texas
The annular eclipse crosses Texas and visits the metropolitan areas of Midland and Odessa, San Antonio, and Corpus Christi. The shadow of the Moon leaves the United States at Padre Island at 12:03 p.m. CDT. At this point, the Moon’s shadow is traversing at 1,722 miles per hour and the eclipse is 51 degrees high in the sky. The maximum duration of annular solar eclipse in Texas is 4 minutes and 53 seconds.
The path of annular solar eclipse over the Yucatan Peninsula
After crossing the Caribbean Sea, the annular solar eclipse makes landfall at the Yucatan Peninsula. Annularity touches three countries here; Mexico, Guatemala, and Belize. Belize City is well located for a duration of eclipse longer than 5 minutes.
The path of annular solar eclipse over Honduras and Nicaragua
Next, the annular solar eclipse sweeps over the island of Roatan and the mainland of Honduras. The duration of annular solar eclipse reaches 5 minutes and 5 seconds near the beach resort of Bluefields, Nicaragua on the Atlantic coast. The major cities of Managua and Tegucigalpa will experience 88% and 89% partial solar eclipse.
The path of annular solar eclipse over Panama
A long stretch of the Pan American highway in Panama is inside the path of annular solar eclipse. Unfortunately, the Panama Canal and Panama City lie just north of the path of annularity, but will experience a deep partial solar eclipse.
The path of annular solar eclipse over Colombia
The city of Cali in Colombia will witness over 3 minutes of annularity in the early afternoon. Bogota and Medellin will experience a deep 88% partial solar eclipse.
The path of annular solar eclipse over Colombia and northwestern Brazil
The path of annular solar eclipse next visits the Amazonian rainforest of western Brazil. The city of Manaus on the Amazon River is just north of the path of annular solar eclipse.
The path of annular solar eclipse over eastern Brazil
The annular solar eclipse then traverses Brazil to Natal on the Atlantic coast. Soon after leaving Brazil just north of Recife, the annular solar eclipse ends at sunset. Given good weather, a ship in this area will see the spectacular sight of the setting annular solar eclipse on the horizon.

Several informative and authoritative websites provide additional content on this and other eclipses. They are:
http://xjubier.free.fr/en/site_pages/solar_eclipses/ASE_2023_GoogleMapFull.html is an excellent online eclipse map that you can use to drill down on a viewing location and learn almost every imaginable eclipse data point. This is a resource developed by Xavier Jubier who authored the computation engine used for these eclipse maps, Solar Eclipse Maestro at http://xjubier.free.fr/en/site_pages/solar_eclipses/Solar_Eclipse_Maestro_Photography_Software.html
The foundational calculations for predicting the circumstances of this eclipse are by Fred Espenak, retired NASA Astrophysicist. He provides more information at http://www.eclipsewise.com/solar/SEprime/2001-2100/SE2023Oct14Aprime.html and his eclipse photography and tips are at http://mreclipse.com/ Many of his books are sold on his website and our website.
The authoritative site for eclipse climatology is http://eclipsophile.com/ by Jay Anderson and Jennifer West. Eclipsophile is an essential resource for planning any eclipse travel explaining regional weather patterns and identifying sites with improved weather odds.
