A total solar eclipse occurred at the Moon’s ascending node of orbit on Wednesday, March 29, 2006,[1][2][3] with a magnitude of 1.0515. 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 1.1 days after perigee (on March 28, 2006, at 8:10 UTC), the Moon's apparent diameter was larger.[4]
This was the second solar eclipse visible in Africa within just 6 months.
Almost all actively visited areas in the path of totality had perfect weather. Many observers reported an unusually beautiful eclipse, with many or all effects visible, and a very nice corona, despite the proximity to the solar minimum. The partial phase of the eclipse was also visible from the International Space Station, where the astronauts on board took spectacular pictures of the moon's shadow on Earth's surface. It initially appeared as though an orbit correction set for the middle of March would bring the ISS into the path of totality, but this correction was postponed.
The Paris Observatory sent a team of students and coordinators to Savalou, Benin. The team took clear images of the corona. A team of Williams College, Massachusetts did many experiments and took images of the corona on the Greek island of Kastellórizo with 3 minutes of totality, which is close to the coast of Turkey and the only place in the European Union covered by the path of totality. The Solar and Heliospheric Observatory also made auxiliary observations to compare images taken from space and from the ground.[6][7][8] Another research simulated the changing colours of the sky in the path of totality with a three-dimensional model while considering multiple scattering. Monte Carlo method was used in the experiment to predict the colour and brightness of the sky. In addition, the direct irradiation of the corona was also studied. The goal was to plan and optimise studies on incoming solar irradiance.[9] Russian scientists studied on coronal polarization in the Baksan River Gorge surrounded by snow mountains in the North Caucasus. The location has an altitude of 1,800 metres and is 25 kilometres from Mount Elbrus, the highest peak in Russia and also Europe.[10]
Libya under Muammar Gaddafi was under sanctions because of bombing the Pan Am Flight 103 and had a strict alcohol ban. It was the least visited region around the Mediterranean. To promote tourism, the Libyan government mobilized 5 state-owned tourism companies to attract more tourists, and built a tent village that could accommodate 7,000 people in Waw an Namus inside the Sahara Desert with excellent observation conditions. However, it was only open to astronomers, while ordinary tourists were directed to Patan, near the border with Egypt. Despite Libya's desire to attract tourists from all over the world, Israelis were still banned from entering the country.[11][12]NASA scientists also did joint observation and research with Libyan scientists, taking images and videos.[8][13]
A team of 20 people from the Chinese Astronomical Society [zh] took images of Baily's beads, corona and prominences in Sallum, Egypt. The weather conditions were good in Sallum and also neighbouring Libya. Then Egyptian President Hosni Mubarak, Minister of Defense Muhammad Tantawi and other officials also went there by helicopter and observed the eclipse with scientists and tourists.[14][15]
The satellite responsible for SKY Network Television, a New Zealand pay TV company, failed the day after this eclipse at around 1900 local time. While SKY didn't directly attribute the failure to the eclipse, they said in a media release that it took longer to resolve the issue because of it, but this claim was rejected by astronomers. The main reason for the failure was because of an aging and increasingly faulty satellite.[16]
Shown below are two tables displaying details about this particular solar eclipse. The first table outlines times at which the moon's penumbra or umbra attains the specific parameter, and the second table describes various other parameters pertaining to this eclipse.[17]
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.
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.[18]
This eclipse is a part of Saros series 139, repeating every 18 years, 11 days, and containing 71 events. The series started with a partial solar eclipse on May 17, 1501. It contains hybrid eclipses from August 11, 1627 through December 9, 1825 and total eclipses from December 21, 1843 through March 26, 2601. There are no annular eclipses in this set. The series ends at member 71 as a partial eclipse on July 3, 2763. 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 61 at 7 minutes, 29.22 seconds on July 16, 2186. This date is the longest solar eclipse computed between 4000 BC and AD 6000.[19] All eclipses in this series occur at the Moon’s ascending node of orbit.[20]
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
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.
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.
