The last time a total solar eclipse was visible across the entire contiguous United States was during the
There are expected to be logistical issues with the influx of visitors, especially for smaller communities.[4][5] There have also been issues with counterfeit eclipse glasses being sold.[6][7][8]
Future total solar eclipses will cross the United States in April 2024 (12 states) and August 2045 (10 states), and annular solar eclipses — meaning the apparent size of the Moon is smaller than that of the Sun — will occur in October 2023 (9 states) and June 2048 (9 states).
Visibility
The total eclipse will have a
The longest duration of totality will be 2 minutes 41.6 seconds at about 37°35′0″N 89°7′0″W / 37.58333°N 89.11667°W in Giant City State Park, just south of Carbondale, Illinois, and the greatest extent (width) will be at 36°58′0″N 87°40′18″W / 36.96667°N 87.67167°W near the village of Cerulean, Kentucky, located in between Hopkinsville and Princeton.[11] This will be the first total solar eclipse visible from the Southeastern United States since the solar eclipse of March 7, 1970, which was only visible from Florida.
A partial solar eclipse will be seen from the much broader path of the
Related eclipses over the United States
This eclipse will be the first total solar eclipse visible from the United States since the solar eclipse of July 11, 1991[12] (which was seen only from part of Hawaii),[13] and the first visible from the contiguous United States since 1979.[14]
The path of totality of the
Some American scientists and interested amateurs seeking to experience a total eclipse participated in a four-day Atlantic Ocean cruise to view the solar eclipse of July 10, 1972 as it passed near Nova Scotia. Organizers of the cruise advertised in astronomical journals and in planetarium announcements emphasizing the lack of future total eclipses observable in U.S. until this 2017 event.[17]
The August 2017 eclipse will be the first with a path of totality crossing the Pacific and Atlantic coasts of the U.S. since 1918. Also, its path of totality makes landfall exclusively within the United States, making it the first such eclipse since the country's independence in 1776. (The path of totality of the eclipse of June 13, 1257, was the last to make landfall exclusively on lands currently part of the United States.[18])
The path of this eclipse crosses the path of the upcoming total solar eclipse of April 8, 2024, with the intersection of the two paths being in southern Illinois in Makanda Township at Cedar Lake just south of Carbondale. A small land area, including the cities of Makanda, Carbondale, Cape Girardeau, Missouri, and Paducah, Kentucky, will thus experience two total solar eclipses within a span of less than seven years.
The solar eclipse of August 12, 2045 will have a very similar path of totality over the U.S., about 400 km (250 mi) to the southwest, also crossing the Pacific and Atlantic coasts of the country; however, duration of totality will last over twice as long.[19]
An eclipse of comparable length (up to 3 minutes, 8 seconds, with the longest eclipse being 6 minutes and 54 seconds) occurred over the contiguous United States on March 7, 1970 along the southern portions of the Eastern Seaboard, from Florida to Virginia.[20]

Planning
Counterfeit eclipse glasses have become a public health issue; deficient solar eclipse filters can quickly cause irreparable eye damage inasmuch as the retina has no pain receptors. In particular, it's not enough that the glasses have a logo and the ISO number 12312-2; customers must be reasonably confident that the glasses have come from a reputable manufacturer and/or authorized dealer. A person should not be able to see much through a safe solar filter except for the Sun itself, sunlight reflected off shiny metal, the hot filament of unfrosted incandescent light bulbs, bright halogen light bulbs, bright LED flashlights, and an arc-welder's torch; a welder's helmet can be used for safe viewing provided it has a filter of 12 or higher. [6][7][8]The American Astronomical Society states that not only must effective glasses dim the Sun to a comfortable level, but they must do so across the whole electromagnetic spectrum, for example also filtering most ultraviolet and infrared light.[6]
Logistically, the demand for
Impact on solar power
The eclipse will cause a reduction of solar power where the shadow reaches solar panels. The North American Electric Reliability Corporation measures impacts of this event,[69] and predicts
minor impacts.
Commemorative stamp
On June 20, 2017,[75] the United States Postal Service released the first application of thermochromic ink to postage stamps in its Total Eclipse of the Sun Forever stamp[76] to commemorate the solar eclipse of August 21, 2017. When pressed with a finger, body heat turns the black circle in the center of the stamp into an image of the full moon. The stamp image is a photo of a total solar eclipse seen in Jalu, Libya, on March 29, 2006. The photo was taken by retired NASA astrophysicist Fred Espenak.[76]
Related eclipses
A partial lunar eclipse took place on August 7, 2017, in the same eclipse season. It was visible over eastern Europe, Africa, Asia, and Australia.

Saros series 145
This solar eclipse is a part of Saros cycle 145, repeating every 18 years, 11 days, 8 hours, containing 77 events. The series started with a partial solar eclipse on January 4, 1639, and reached a first annular eclipse on June 6, 1891. It was a hybrid event on June 17, 1909, and total eclipses from June 29, 1927, through September 9, 2648. The series ends at member 77 as a partial eclipse on April 17, 3009. The longest eclipse will occur on June 25, 2522, with a maximum duration of totality of 7 minutes, 12 seconds. All eclipses in this series occurs at the Moon's ascending node.

Metonic series
The metonic series repeats eclipses every 19 years (6939.69 days), lasting about 5 cycles. Eclipses occur in nearly the same calendar date. In addition, the octon subseries repeats 1/5 of that or every 3.8 years (1387.94 days). All eclipses in this table occur at the Moon's ascending node.
