Solar eclipse of September 23, 2090

Summary

A total solar eclipse will occur on September 23, 2090. 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. This solar eclipse will be the first total solar eclipse visible from Great Britain since August 11, 1999, and the first visible from Ireland since May 22, 1724. 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.

Tritos series edit

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 edit

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.
