Solar eclipse of September 23, 2090

A total solar eclipse will occur on Saturday, 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 and the Isle of Wight, and a partially eclipsed sun will be visible in Birmingham, London, Exeter, Cardiff, Belfast, Dublin, Weston Super Mare, Bristol and Oxford.

Solar eclipses 2087–2090

This eclipse is a member of a semester series. An eclipse in a semester series of solar eclipses repeats approximately every 177 days and 4 hours (a semester) at alternating nodes of the Moon's orbit.[1]

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.

gollark: An undirected graph, which is nice, but I probably want to do a similar thing with directed graphs at some point.
gollark: It is an adjacency matrix for a graph.
gollark: Or I could just compress an actual adjacency list, but boooooring.
gollark: Thusly, I somehow need to store VAST highly sparse bit matrices efficiently another way. I'm thinking quadtrees.
gollark: It appears that the algorithm or possibly library I wanted to use for efficiently storing sparse bit matrices was in fact 3 slow, and thus unusable for the sheer speed of osmarksßsearchengine™ 1.4..6..4....1.
