There’s a total eclipse of the sun coming up on March 20, 2015 – the day of the vernal equinox. A total eclipse of the sun and the March equinox do fall on the same date this year. After this 2015 equinox eclipse, the next solar #eclipse at the March equinox will happen on March 20, 2034. Then there will be two more in this century: 2053 and 2072.
Note the spacing of 19 years between these four eclipses of the March #equinox sun…there are cycles acting within cycles. This 19-year lunar period is known as the Metonic cycle. Amazingly, you can project this 19-year cycle for centuries into the future (or past) to figure out when the new moon will occur on the #March equinox.
A solar eclipse can only happen at new moon. For a solar eclipse to take place at the vernal equinox, therefore, the new moon must come on the equinox date. A total solar eclipse can be seen only along a narrow pathway across Earth’s surface. In the case of the March 20, 2015 eclipse that pathway cuts east of Iceland, across the North Atlantic.
We find that four years of the 21st century (2001-2100) feature a #March equinox solar eclipse: 2015, 2034, 2053 and 2072. There will be no solar eclipses taking place on the March equinox during the 22nd century (2101-2200) and 23rd century (2201-2300). Spring is 1 of the 4 main seasons. The Vernal Equinox Equal is (12) hours of day and night equally. The date is significant in #Christianity because #Easter always falls on the first Sunday after the first full moon after the vernal equinox. It is no coincidence that early #Egyptians built the Great #Sphinx so that it pointed directly toward the rising Sun on the day of the vernal equinox. Some view this transition as a victory of light (or life, rebirth, resurrection) over the powers of darkness (death). The monoliths at #Stonehenge , mark the position of the rising sun on the Vernal #Equinox . In Central America the Ancient Mayan Caracol Tower and Temples of the #Sun and #Moon also have alignments that coincide with the sun’s position on the Vernal Equinox. #science #astronomy #ancient #cycles
