A total solar eclipse will occur on Monday, May 1, 2079, with a maximum eclipse at 10:48:25.6 UTC (10:50:12.8 TD). A solar eclipse occurs when the Moon passes between Earth and the Sun, thereby totally or partly obscuring the image of the Sun for a viewer on Earth. A total solar eclipse occurs when the Moon's apparent diameter is larger than the Sun's, blocking all direct sunlight, turning day into darkness. Totality occurs in a narrow path across Earth's surface, with the partial solar eclipse visible over a surrounding region thousands of kilometres wide. The eclipse will be visible in Greenland, parts of eastern Canada (including Newfoundland and Labrador, New Brunswick, Nova Scotia and Prince Edward Island) and parts of the northeastern United States (including Maine, New Hampshire, Vermont, Connecticut, Rhode Island, Massachusetts, New York, Pennsylvania and New Jersey).
Visible cities[]
The Path of totality will start in eastern Pennsylvania. A total eclipse will be visible along the path of Philadelphia, New York City, Boston and Portland in the United States. Partial eclipses will be visible in Charlotte, Richmond, Cleveland, Detroit, Chicago, Washington, D.C., and Buffalo. In Canada, the total eclipse can be visible in Halifax, and St. John, while the partial eclipse can be seen in Montreal, Toronto, Ottawa, and most of northern Canada. The path then passes directly through Nuuk, making it visible to most of Greenland. The path will end near the Bering Strait. a partial eclipse can be visible in a very small part of South America, Northern Africa, Europe and Northern Asia (Mostly Russia).

Saros 149[]
Solar saros 149, repeating every about 18 years and 11 days, contains 71 events. The series started with a partial solar eclipse on August 21, 1664. It has total eclipses from April 9, 2043, to October 2, 2331. The series ends at member 71 as a partial eclipse on September 28, 2926. The longest total eclipse will be on July 17, 2205, at 4 minutes and 10 seconds.[2]

Inex series[]
This eclipse is a part of the long period inex cycle, repeating at alternating nodes, every 358 synodic months (≈ 10,571.95 days, or 29 years minus 20 days). Their appearance and longitude are irregular due to a lack of synchronization with the anomalistic month (period of perigee). However, groupings of 3 inex cycles (≈ 87 years minus 2 months) comes close (≈ 1,151.02 anomalistic months), so eclipses are similar in these groupings. In the 19th century:
- Solar saros 140: total solar eclipse of October 29, 1818
- Solar saros 141: annular solar eclipse of October 9, 1847
- Solar saros 142: total solar eclipse of September 17, 1876

- Solar saros 152: total solar eclipse of March 2, 2166
- Solar saros 153: annular solar eclipse of February 10, 2195
Tritos series[]
This eclipse is a part of a tritos cycle, repeating at alternating nodes every 135 synodic months (≈ 3986.63 days, or 11 years minus 1 month). Their appearance and longitude are irregular due to a lack of synchronization with the anomalistic month (period of perigee), but groupings of 3 tritos cycles (≈ 33 years minus 3 months) come close (≈ 434.044 anomalistic months), so eclipses are similar in these groupings.

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.
