A total solar eclipse will occur at the Moon's ascending node of orbit on Saturday, September 23, 2090,[1] with a magnitude of 1.0562.

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 4 hours after perigee (on September 23, 2090, at 12:40 UTC), the Moon's apparent diameter will be larger.

A partial solar eclipse will also be visible for parts of North America, Western Europe, and West Africa.

The totality will be visible in southern Greenland, Valentia, West Cork, Poole, Newquay, Plymouth, Southampton, Isle of Wight, northern France (including Paris and Rennes) and south Belgium and a partially eclipsed sun will be visible in Birmingham, London, Exeter, Cardiff, Belfast, Dublin, Weston Super Mare, Bristol and Oxford.

Their appearance and longitude are irregular due to a lack of synchronization with the anomalistic month (period of perigee).
