# Solar eclipse of November 23, 2003

A total solar eclipse occurred at the Moon's descending node of orbit between Sunday, November 23 and Monday, November 24, 2003, with a magnitude of 1.0379. 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 25 minutes before perigee (on November 23, 2003, at 23:15 UTC), the Moon's apparent diameter was near its maximum. Perigee did occur just past the greatest point of this eclipse.
For most solar eclipses the path of totality moves eastwards. In this case the path moved south and then west round Antarctica.
Totality was visible from a corridor in eastern Antarctica. A partial eclipse was visible for parts of Australia, New Zealand, Antarctica, southern Chile, and southern Argentina.

## Observations

A Russian icebreaker departed from Port Elizabeth, South Africa carrying tourists to observe the eclipse near the Shackleton Ice Shelf and Novolazarevskaya Station, and then sailed to Hobart, Tasmania. About 100 people from 15 countries were on board, including Iranian amateur astronomer Babak Amin Tafreshi, NASA's Goddard Space Flight Center astrophysicist Fred Espenak, Williams College professor Jay Pasachoff. There are also about 200 scientists and tourists taking two commercial charter flights to observe it over Antarctica. This was the first time humans observed a total solar eclipse from 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 November 2003 :
| November 9 Ascending node (full moon) | November 23 Descending node (new moon) |
| Total lunar eclipse Lunar Saros 126 | Total solar eclipse Solar Saros 152 |

### Solar eclipses of 2000–2003

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 February 5, 2000 and July 31, 2000 occur in the previous lunar year eclipse set.
Solar eclipse series sets from 2000 to 2003 :
| Ascending node | Ascending node | Ascending node | Descending node | Descending node | Descending node |

### Saros 152

This eclipse is a part of Saros series 152, repeating every 18 years, 11 days, and containing 70 events. The series started with a partial solar eclipse on July 26, 1805. It contains total eclipses from November 2, 1967 through September 14, 2490; hybrid eclipses from September 26, 2508 through October 17, 2544; and annular eclipses from October 29, 2562 through June 16, 2941. The series ends at member 70 as a partial eclipse on August 20, 3049. 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 will be produced by member 30 at 5 minutes, 16 seconds on June 9, 2328, and the longest duration of annularity will be produced by member 53 at 5 minutes, 20 seconds on February 16, 2743. All eclipses in this series occur at the Moon’s descending node of orbit.

### 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 September 12, 1931 and July 1, 2011 :
| September 11–12 | June 30–July 1 | April 17–19 | February 4–5 | November 22–23 |

### 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.
The partial solar eclipses on November 16, 2134 (part of Saros 164) and October 16, 2145 (part of Saros 165) are also a part of this series but are not included in the table below.
Series members between 1801 and 2069 :
| June 6, 1807 (Saros 134) | May 5, 1818 (Saros 135) | April 3, 1829 (Saros 136) | March 4, 1840 (Saros 137) | February 1, 1851 (Saros 138) |
| December 31, 1861 (Saros 139) | November 30, 1872 (Saros 140) | October 30, 1883 (Saros 141) | September 29, 1894 (Saros 142) | August 30, 1905 (Saros 143) |
| July 30, 1916 (Saros 144) | June 29, 1927 (Saros 145) | May 29, 1938 (Saros 146) | April 28, 1949 (Saros 147) | March 27, 1960 (Saros 148) |

### 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 :
| April 13, 1801 (Saros 145) | March 24, 1830 (Saros 146) | March 4, 1859 (Saros 147) |
| February 11, 1888 (Saros 148) | January 23, 1917 (Saros 149) | January 3, 1946 (Saros 150) |
