Macdonald cycle An eclipse cycle equal to 299 years and about ten and a half months, always occurring on the same node. Peter Macdonald found that a series of eclipses of especially long duration visible from Britain occurs with this interval in the period AD 1 to 3000. [3] A Macdonald series has around ten eclipses and lasts about 3000 years.
A "deep eclipse" (or "deep occultation") is when a small astronomical object is behind a bigger one. [2] [3] The term eclipse is most often used to describe either a solar eclipse, when the Moon's shadow crosses the Earth's surface, or a lunar eclipse, when the Moon moves into the Earth's shadow. However, it can also refer to such events beyond ...
Solar eclipses are grouped by their saros number, each series lasts between 1200 and 1600 years and contains from 69 to 87 solar eclipses (most often 70 to 73).Solar eclipses in odd series exist at the ascending node of the Moon's orbit, and even series occur at the descending nodes.
A solar eclipse occurs when the Moon passes between Earth and the Sun, thereby obscuring the view of the Sun from a small part of the Earth, ... Modern history.
Eclipse occurring prior to Xerxes' first march against Greece. The exact dating has been debated, as the writings of Herodotus (who chronicled the eclipse) give a date for which there was no eclipse visible in that area of the world. [7] August 3, 431 BC Annular 48 – 14:54:51:8 – 01m04.5s Greece, Mediterranean Sea
The first umbral eclipse of the series was an annular eclipse on 6 June 1891, followed by a hybrid eclipse on 17 June 1909. Beginning on 29 June 1927 the series produces total eclipses, ending on 9 September 2648. The longest duration eclipse in the cycle will be member 50 at 7 minutes and 12 seconds in length on June 25, 2522.
Below is a list of all total eclipses at least 7 minutes long that will occur between the 22nd and 30th centuries. Of the listed eclipses, the first five are in Solar Saros 139, the next three are in Solar Saros 145, and the final four are in Solar Saros 170.
