A partial lunar eclipse will take place on Friday 28 August 2026. The moon will be almost be inside the umbra, but not quite be contained within the umbral shadow at greatest eclipse.
This lunar eclipse follows the total solar eclipse of 12 August 2026.
This eclipse is the fourth and last of an almost tetrad, with others being 14 Mar 2025 (T), 07 Sep 2025 (T) and 03 Mar 2026 (T). In this almost tetrad, it's the only partial lunar eclipse. An almost tetrad occurs when has four consecutive lunar eclipses that has an umbral eclipse magnitude of 0.9 or greater without lunar eclipses that has an umbral eclipse magnitude of 0.89999 or smaller.
It will be completely visible over South and eastern North America, will be seen rising over the rest of North America, and setting over Africa and Europe.

Lunar saros series 138 has 26 total eclipses between September 7, 2044 and March 24, 2369. The longest eclipse will be on January 7, 2243, and last for 102 minutes.
Partial eclipses will occur between June 24, 1918 and August 13, 2603. Penumbral eclipses will occur between October 15, 1521 and March 30, 2982. [1]
The Metonic cycle repeats nearly exactly every 19 years and represents a Saros cycle plus one lunar year. Because it occurs on the same calendar date, the Earth's shadow will be in nearly the same location relative to the background stars.

A lunar eclipse will be preceded and followed by solar eclipses by 9 years and 5.5 days (a half saros). [2] This lunar eclipse is related to two total solar eclipses of Solar Saros 145.

A total lunar eclipse took place on 3 March 2007, the first of two eclipses in 2007. The Moon entered the penumbral shadow at 20:18 UTC, and the umbral shadow at 21:30 UTC. The total phase lasted between 22:44 UTC and 23:58 UTC with a distinctive brick-red shade. The Moon left the umbra shadow at 01:11 UTC and left the penumbra shadow at 02:24 UTC 2007-03-04. The second lunar eclipse of 2007 occurred on 28 August.
A total lunar eclipse took place on Tuesday 4 May 2004, the first of two total lunar eclipses in 2004, the second being on 28 October 2004.
A total lunar eclipse will take place on Tuesday, March 3, 2026, the first of two lunar eclipses in 2026.
A total lunar eclipse took place at the Moon's descending node of the orbit on Tuesday, September 16, 1997, the second of two lunar eclipses in 1997. A shallow total eclipse saw the Moon in relative darkness for 1 hour, 1 minute and 30.8 seconds. The Moon was 19.094% of its diameter into the Earth's umbral shadow, and should have been significantly darkened. The partial eclipse lasted for 3 hours, 16 minutes and 28.2 seconds in total. The penumbral eclipse lasted for 5 hours, 8 minutes and 20.1 seconds. The partial eclipse lasted for 3 hours, 16 minutes and 28.2 seconds. The total eclipse lasted for 1 hour, 1 minute and 30.8 seconds. Maximum eclipse was at 18:46:39.1 UTC. The moon's apparent diameter was extremely large because occurred only 3 hours and 21 minutes past perigee. The Moon was only 356,986 km of the Earth at greatest eclipse.
A partial lunar eclipse took place on Monday, March 24, 1997, the first of two lunar eclipses in 1997.
A total lunar eclipse took place on Friday, September 27, 1996, the second of two lunar eclipses in 1996, the first being on Thursday, April 4. This is the 41st member of Lunar Saros 127. The previous event is the September 1978 lunar eclipse. The next event is the October 2014 lunar eclipse.
A total lunar eclipse will take place between Monday and Tuesday, June 25-26, 2029. A central total eclipse lasting 1 hour and 41 minutes 53 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 color at maximum eclipse. It will be able to be seen from most of the Americas, Western Europe and Africa. The partial eclipse will last for 3 hours and 39 minutes 32 seconds in total.
A total lunar eclipse occurred on 15–16 May 2022, the first of two total lunar eclipses in 2022. The event occurred near lunar perigee; as a result, this event was referred to some in media coverage as a "super flower blood moon" and elsewhere as a "super blood moon", a supermoon that coincides with a total lunar eclipse. This was the longest total lunar eclipse visible from nearly all of North America since August 17, 1989 until the next eclipse on November 8.
A total lunar eclipse took place on Thursday, April 4, 1996, the first of two total lunar eclipses in 1996, the other being on Friday, September 27. The Moon passed through the center of the Earth's shadow.
A total lunar eclipse took place on Thursday, April 24, 1986, the first of two total lunar eclipses in 1986, the second being on October 17, 1986. The Moon was plunged into darkness for 1 hour, 3 minutes and 34.8 seconds, in a deep total eclipse which saw the Moon 20.217% of its diameter inside the Earth's umbral shadow. The visual effect of this depends on the state of the Earth's atmosphere, but the Moon may have been stained a deep red colour. The partial eclipse lasted for 3 hours, 18 minutes and 46.8 seconds in total. The Moon was just 1.2 days before perigee, making it 5.3% larger than average.
A penumbral lunar eclipse took place on Thursday, March 3, 1988, the first of two lunar eclipses in 1988, the second being on August 27, 1988. Earlier sources compute this as a 0.3% partial eclipse lasting under 14 minutes, and newest calculations list it as a penumbral eclipse that never enters the umbral shadow. In a rare total penumbral eclipse, the entire Moon was partially shaded by the Earth, and the shading across the Moon should have been quite visible at maximum eclipse. The penumbral phase lasted for 4 hours, 53 minutes and 50.6 seconds in all, though for most of it, the eclipse was extremely difficult or impossible to see. The Moon was 2.2 days after apogee, making it 6.1% smaller than average.
A total lunar eclipse will take place on Friday, March 14, 2025, the first of two total lunar eclipses in 2025. The Moon will take place near apogee during this eclipse, making it appear smaller than usual. The second eclipse will take place on 7-8 September 2025, happening near perigee. Occurring only 3.4 days before apogee, the Moon's apparent diameter will be 5.4% smaller than average.
A total lunar eclipse will take place on 7-8 September 2025. The Moon will barely miss the center of the Earth's shadow. It will be the second of two total lunar eclipses. Occurring roughly 3 days before perigee, the Moon will appear larger than usual.
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.
A total lunar eclipse will take place on June 28, 2094. 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 0.0288 and an umbral eclipse magnitude of 1.8234, this is the greatest eclipse in Saros series 131 as well as the second largest and darkest lunar eclipse of the 21st century.
