A total solar eclipse took place on June 21, 2001, with a magnitude of 1.0495. 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.

Visibility[edit]

It was visible from a narrow corridor in the southern Atlantic Ocean and southern Africa, including Angola, Zambia, Zimbabwe, Mozambique, the southern tip of Malawi, and Madagascar. A partial eclipse was seen from the much broader path of the Moon's penumbra, including eastern South America and most of Africa.

Solar eclipses 2000-2003[edit]

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.[1]

Note: Partial solar eclipses on February 5, 2000 and July 31, 2000 occur in the previous lunar year set.

Saros 127[edit]

It is a part of Saros cycle 127, repeating every 18 years, 11 days, containing 82 events. The series started with partial solar eclipse on October 10, 991 AD. It contains total eclipses from May 14, 1352 through August 15, 2091. The series ends at member 82 as a partial eclipse on March 21, 2452. The longest duration of totality was 5 minutes, 40 seconds on August 30, 1532.[2]

Tritos series[edit]

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.


Metonic series[edit]

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).
