# Solar eclipse of October 7, 1801

A partial solar eclipse occurred at the Moon's descending node of orbit on Wednesday, October 7, 1801, with a magnitude of 0.3505. 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.
The partial solar eclipse was visible for parts of modern-day New Zealand 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. The first and last eclipse in this sequence is separated by one synodic month.
Eclipse season of September–October 1801 :
| September 8 Descending node (new moon) | September 22 Ascending node (full moon) | October 7 Descending node (new moon) |
| Partial solar eclipse Solar Saros 112 | Total lunar eclipse Lunar Saros 124 | Partial solar eclipse Solar Saros 150 |

### Solar eclipses of 1798–1801

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 eclipses on [h] occur in the previous lunar year eclipse set, and the partial solar eclipses on March 14, 1801 and September 8, 1801 occur in the next lunar year eclipse set.
Solar eclipse series sets from 1798 to 1801 :
| Ascending node | Ascending node | Ascending node | Descending node | Descending node | Descending node |

| 115 | May 15, 1798 Annular | −0.8744 | 120 | November 8, 1798 Total | 0.8270 |

### Saros 150

This eclipse is a part of Saros series 150, repeating every 18 years, 11 days, and containing 71 events. The series started with a partial solar eclipse on August 24, 1729. It contains annular eclipses from April 22, 2126 through June 22, 2829. There are no hybrid or total eclipses in this set. The series ends at member 71 as a partial eclipse on September 29, 2991. 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 annularity will be produced by member 45 at 9 minutes, 58 seconds on December 19, 2522. All eclipses in this series occur at the Moon’s descending node of orbit.
Series members 5–27 occur between 1801 and 2200: :
| 5 | 6 | 7 |
| October 7, 1801 | October 19, 1819 | October 29, 1837 |

### 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.
2 eclipse events between October 7, 1801 and July 26, 1805 :
| October 7 | July 26 |
| 150 | 152 |
| October 7, 1801 | July 26, 1805 |

### 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 1801 and 1823 :
| October 7, 1801 (Saros 150) | September 5, 1812 (Saros 151) | August 6, 1823 (Saros 152) |

### 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 1946 :
| October 7, 1801 (Saros 150) | September 17, 1830 (Saros 151) | August 28, 1859 (Saros 152) |
| August 7, 1888 (Saros 153) | July 19, 1917 (Saros 154) | June 29, 1946 (Saros 155) |
