# Solar eclipse of March 28, 1968

A partial solar eclipse occurred at the Moon's ascending node of orbit between Thursday, March 28 and Friday, March 29, 1968, with a magnitude of 0.899. 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 partial solar eclipse occurs in the polar regions of the Earth when the center of the Moon's shadow misses the Earth.
A partial eclipse was visible for parts of eastern Oceania and Antarctica.

## 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 March–April 1968 :
| March 28 Ascending node (new moon) | April 13 Descending node (full moon) |
| Partial solar eclipse Solar Saros 119 | Total lunar eclipse Lunar Saros 131 |

### Solar eclipses of 1968–1971

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 July 22, 1971 occurs in the next lunar year eclipse set.
Solar eclipse series sets from 1968 to 1971 :
| Ascending node | Ascending node | Ascending node | Descending node | Descending node | Descending node |
| Saros | Map | Gamma | Saros | Map | Gamma |

### Saros 119

This eclipse is a part of Saros series 119, repeating every 18 years, 11 days, and containing 71 events. The series started with a partial solar eclipse on May 15, 850 AD. It contains total eclipses on August 9, 994 AD and August 20, 1012; a hybrid eclipse on August 31, 1030; and annular eclipses from September 10, 1048 through March 18, 1950. The series ends at member 71 as a partial eclipse on June 24, 2112. 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 10 at 32 seconds on August 20, 1012, and the longest duration of annularity was produced by member 44 at 7 minutes, 37 seconds on September 1, 1625. All eclipses in this series occur at the Moon’s ascending node of orbit.
Series members 54–71 occur between 1801 and 2112: :
| 54 | 55 | 56 |
| December 21, 1805 | January 1, 1824 | January 11, 1842 |

### 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.
20 eclipse events between June 10, 1964 and August 21, 2036 :
| June 10–11 | March 28–29 | January 14–16 | November 3 | August 21–22 |

### 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) |

### 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 :
