An annular eclipse of the Sun occurs on Saturday 14 October, 2023 UT, lasting from 15:03–20:55 UT. The Sun will be 95% covered in a moderate annular eclipse, lasting 5 minutes and 17 seconds and covering a broad path up to 187 km wide. It will be visible in the USA, central America and south America. The partial eclipse will be visible across most of the Americas.

The timings of the phases of the overall eclipse worldwide are as follows. In any particular place it will be seen for a significantly shorter duration as the shadow moves across the Earth:

Partial eclipse begins: 15:03:38 UT
Annular eclipse begins: 16:09:51 UT
Maximum eclipse: 17:59:21 UT
Annular eclipse ends: 19:48:53 UT
Partial eclipse ends: 20:55:07 UT

During this eclipse the Sun will be 0.534° in apparent diameter, 0.3% larger than average. The Moon will be just 4 days past apogee, making it fairly small. At maximum eclipse it will be 0.509° in apparent diameter, which is 4.2% smaller than average; this is not large enough to cover the Sun, which is why this is an annular eclipse. The statistics page has information on the ranges of the sizes of the Sun and Moon.

The USA

The annular eclipse will make landfall in Oregon at about 16:18 UT, and then clip the north-east corner of California before crossing into Nevada, Utah, and Arizona, pssing right over Albuquerque at around 16:37 UT. It then crosses New Mexico and Texas, and reaches the Gulf at Corpus Christi at 16:58 UT.

Mexico, Central America

The annular path reaches the Yucatan north of Campeche at 17:24 UT, and then crosses Belize, passing right over Belize City at 17:34 UT. It then crosses over to Honduras, reaching land at about 17:41 UT, then Nicaragua at 17:48 UT, then pass back over the Caribbean at 17:56 UT.

The edge of the annular path just grazes the east coast of Costa Rica then passs into Panama at about 18:06 UT, with the centreline hitting the mainland at 18:10 UT. It passes just offshore of Punta Mala at 18:16 UT.

South America

The eclipse path reaches the Colombian coast starting around 18:24 UT, passes over Tulua at 18:32 UT, then crosses into Brazil at about 18:56 UT. It then crosses right over Brazil, passing Picos about 19:43 UT, then reaches the coast south of Natal at 19:46 UT. It ends just moments later in the Atlantic.

Interactive Map

This map shows the visibility of the eclipse. The shaded area will see the annular solar eclipse; however, near the edges of this area, the eclipse will be very short. The bold line shows the centre of the path, where the eclipse will last longest, so this is where you want to be if possible.

Use the zoom controls to zoom in and out; hover your mouse over any point on the centreline to see the time and duration of the eclipse at that point. You can pan and zoom the map to see detail for any part of the eclipse path.

Note that while all dates and times on this site (except where noted) are in UT, which is within a second of civil time, the dates and times shown in NASA's eclipse listings are in the TDT timescale.

The Sun and Moon distances are shown in km, and as a percentage of their minimum - maximum distances; hence 0% is the closest possible (Earth's perihelion, or the Moon's closest possible perigee) and 100% is the farthest (aphelion, the farthest apogee). The statistics page has information on the ranges of sizes of the Sun and Moon.
