A total lunar eclipse took place on Friday, April 22, 1921. This was the first total lunar eclipse of Saros cycle 130. A shallow total eclipse saw the Moon in relative darkness for 40 minutes and 6 seconds. The Moon was approximately 7% of its diameter into the Earth's umbral shadow, and should have been significantly darkened. The partial eclipse lasted for 3 hours and 22 minutes in total.

Saros series

Lunar saros series 130, repeating every 18 years and 11 days, has a total of 71 lunar eclipse events including 56 umbral lunar eclipses (42 partial lunar eclipses and 14 total lunar eclipses). Solar Saros 137 interleaves with this lunar saros with an event occurring every 9 years 5 days alternating between each saros series.

June 2076 lunar eclipse Central lunar eclipse

A total lunar eclipse will take place on June 17, 2076. The moon will pass through the center of the Earth's shadow. While the visual effect of a total eclipse is variable, the Moon may be stained a deep orange or red color at maximum eclipse. With a gamma value of only -0.0452 and an umbral eclipse magnitude of 1.7943, this is the second greatest eclipse in Saros series 131 as well as the largest and darkest lunar eclipse between June 26, 2029 and June 28, 2094. Overall, it will be the third largest and darkest lunar eclipse of the 21st century. While it will have similar values to the lunar eclipse of July 16, 2000, totality will not last over 106 minutes due to the moon's relatively large apparent size as seen from Earth and greater speed in its elliptical orbit. Totality's expected to last 100 minutes 34 seconds from 9:11:39 to 10:52:15 with the greatest point at 10:01:57 UTC.

Solar Saros 137

Saros cycle series 137 for solar eclipses occurs at the Moon's ascending node. It repeats every 18 years, 11 days, and contains 70 events. 55 of these are umbral eclipses and other 15 of these are partial solar eclipses. All eclipses in this series occurs at the Moon's ascending node.

Saros cycle series 130 for lunar eclipses occurs at the moon's ascending node, 18 years 11 and 1/3 days. It contains 71 events. Solar saros 137 interleaves with this lunar saros with an event occurring every 9 years 5 days alternating between each saros series.

June 2123 lunar eclipse Spectacular long central lunar eclipse

A total eclipse of the Moon occurs on Wednesday June 9, 2123, with maximum eclipse at 05:06 UT. A dramatic total eclipse lasting 106 minutes and 6 seconds 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 05:06:28 UT. This will be the longest Total Lunar Eclipse since 16 July 2000, and the longest one until 12 May 2264 and 27 July 3107, though the eclipse on June 19, 2141 will be nearly identical in all aspects. This will also be the longest of the 22nd century and the second longest of the 3rd millennium. The eclipse on June 19, 2141 will be the second longest of the 22nd century and the third longest of the third millennium.
