A total solar eclipse will occur at the Moon's descending node of orbit on Monday, September 14, 2099, with a magnitude of 1.0684. 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. Occurring about 5 hours before perigee (on September 15, 2099, at 12:20 UTC), the Moon's apparent diameter will be larger.
The eclipse will begin at sunrise off the western coast of Canada, and move eastern across Canada (British Columbia, Alberta, and Saskatchewan) and the northern states of the United States (Montana, North Dakota, South Dakota, Minnesota, Wisconsin, Illinois, Indiana, Michigan, Ohio, Pennsylvania, West Virginia, Maryland, Virginia and North Carolina). The eclipse will end in the Atlantic Ocean, with partial visibility in parts of Central America, the Caribbean, northern South America, the Iberian Peninsula, West Africa and throughout the entirety of North.
The path of totality will pass through the cities of Madison, Wisconsin, and Grand Rapids, Michigan. The last time totality was visible over these two locations was respectively May 16, 1379, and April 18, 1558.
Although this solar eclipse does pass over a few large cities such as Minneapolis and Virginia Beach, it fails to offer totality in several major cities nearby, including most of Chicago and all of Washington D.C., Detroit, Cincinnati and Cleveland. Moreover, in Canada, the cities of Moose Jaw and Regina will be directly north of the path, but not in it.
Shown below are two tables displaying details about this particular solar eclipse. The first table outlines times at which the Moon's penumbra or umbra attains the specific parameter, and the second table describes various other parameters pertaining to this eclipse.
This eclipse is part of an eclipse season, a period, roughly every six months, when eclipses occur. Only two (or occasionally three) eclipse seasons occur each year, and each season lasts about 35 days and repeats just short of six months (173 days) later; thus two full eclipse seasons always occur each year. Either two or three eclipses happen each eclipse season. In the sequence below, each eclipse is separated by a fortnight.
