# Solar eclipse of April 21, 2088

A total solar eclipse will occur at the Moon's descending node of orbit on Wednesday, April 21, 2088, with a magnitude of 1.0474. 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. Occurring about 1.8 days before perigee (on April 23, 2088, at 5:10 UTC), the Moon's apparent diameter will be larger.
The path of totality will be visible from parts of Cape Verde, Mauritania, Western Sahara, northern Mali, Algeria, Tunisia, Malta, southern Italy, Greece, Turkey, Georgia, southern Russia, Kazakhstan, Uzbekistan, Kyrgyzstan, and western China. A partial solar eclipse will also be visible for parts of eastern Canada, Greenland, Europe, West Africa, North Africa, the Middle East, Central Asia, South Asia, and Southeast Asia.
Note that the central line of this total solar eclipse follows a path extremely similar to that of the annular eclipse that occurred 112 years earlier on April 29, 1976.

## Eclipse season

This eclipse is part of an eclipse season, a period, roughly every six months, when eclipses occur. Only two (or occasionally three) eclipse seasons occur each year, and each season lasts about 35 days and repeats just short of six months (173 days) later; thus two full eclipse seasons always occur each year. Either two or three eclipses happen each eclipse season. In the sequence below, each eclipse is separated by a fortnight.
Eclipse season of April–May 2088 :
| April 21 Descending node (new moon) | May 5 Ascending node (full moon) |
| Total solar eclipse Solar Saros 130 | Partial lunar eclipse Lunar Saros 142 |

### Solar eclipses of 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.
The partial solar eclipse on June 1, 2087 occurs in the previous lunar year eclipse set.
Solar eclipse series sets from 2087 to 2090 :

### Saros 130

This eclipse is a part of Saros series 130, repeating every 18 years, 11 days, and containing 73 events. The series started with a partial solar eclipse on August 20, 1096. It contains total eclipses from April 5, 1475 through July 18, 2232. There are no annular or hybrid eclipses in this set. The series ends at member 73 as a partial eclipse on October 25, 2394. Its eclipses are tabulated in three columns; every third eclipse in the same column is one exeligmos apart, so they all cast shadows over approximately the same parts of the Earth.
The longest duration of totality was produced by member 30 at 6 minutes, 41 seconds on July 11, 1619. All eclipses in this series occur at the Moon’s descending node of orbit.
Series members 41–62 occur between 1801 and 2200: :

### 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 descending node.
22 eclipse events between July 3, 2065 and November 26, 2152 :

### 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.
Series members between 1837 and 2200 :
| April 5, 1837 (Saros 107) | March 5, 1848 (Saros 108) | February 3, 1859 (Saros 109) | | December 2, 1880 (Saros 111) |
| | | August 31, 1913 (Saros 114) | July 31, 1924 (Saros 115) | June 30, 1935 (Saros 116) |
| May 30, 1946 (Saros 117) | April 30, 1957 (Saros 118) | March 28, 1968 (Saros 119) | February 26, 1979 (Saros 120) | January 26, 1990 (Saros 121) |
| December 25, 2000 (Saros 122) | November 25, 2011 (Saros 123) | October 25, 2022 (Saros 124) | September 23, 2033 (Saros 125) | August 23, 2044 (Saros 126) |

### Inex series

This eclipse is a part of the long period inex cycle, repeating at alternating nodes, every 358 synodic months (≈ 10,571.95 days, or 29 years minus 20 days). Their appearance and longitude are irregular due to a lack of synchronization with the anomalistic month (period of perigee). However, groupings of 3 inex cycles (≈ 87 years minus 2 months) comes close (≈ 1,151.02 anomalistic months), so eclipses are similar in these groupings.
Series members between 1801 and 2200 :
| October 20, 1827 (Saros 121) | September 29, 1856 (Saros 122) | September 8, 1885 (Saros 123) |
