June 2123 lunar eclipse

A total eclipse of the Moon occurs on Wednesday June 9, 2123, with maximum eclipse at 05:02 UT. A dramatic total eclipse lasting 1 hour and 46 minutes will plunge the full Moon into deep darkness, as it passes right through the centre of the Earth's umbral shadow. While the visual effect of a total eclipse is variable, the Moon may be stained a deep orange or red colour at maximum eclipse. This will be a great spectacle for everyone who sees it. The partial eclipse will last for 3 hours and 56 minutes in total. The penumbral eclipse lasts for 6 hours and 14 minutes. Maximum eclipse is at 05:02:09 UT.[3]

Lunar eclipses are related by many different eclipse cycles. The Saros cycle (18 years and 10 days) repeats the most consistently due three coinciding periods, and continue over 70 events (1200+ years). Eclipses are identified by a Saros number and a member index within each series.The lunar year (354 days) and Metonic cycles (19 years) are short period last only 8 to 10 events. The Metonic cycle is equal to one Saros cycle plus one lunar year, and so the two series progress in parallel.The Inex cycle (29 years minus 20 days) can last tens of thousands of years, so long that long perturbations in the moon's path must be taken into account for prediction. Also the eclipse qualities are less inconsistent because the moon is at different significantly positions in its elliptical orbit in sequential events. Similarly for the shorter Tritos cycle (10 years and 31 days), repeats less consistently for the same reason.

Saros series

Lunar saros series 132, repeating every 18 years and 11 days, has a total of 71 lunar eclipse events including 44 umbral lunar eclipses (32 partial lunar eclipses and 12 total lunar eclipses).

There are 11 series events between 1901 and 2100, grouped into threes (called an exeligmos), each column with approximately the same viewing longitude on earth.
