Cycle #17 (Eclipse & Equinox)

Cycle #17 :: 09-Mar-2006 to 21-Mar-2006
Penumbral Lunar Eclipse — 14-March

"According to Belgian eclipse expert Jean Meeus [1997] this is one of only five such events during the 21st century. Greatest eclipse occurs at 23:48 UT with a penumbral magnitude of 1.0565. At that instant, the Moon will stand midway in the penumbral shadow. The Moon's northern limb will lie 1.6 arc-minutes from the shadow's outer edge while the southern limb be 1.6 arc-minutes from the edge of the umbra." {info}{img}{primer}.

Charting the Eclipse Factor — A total eclipse of the Sun occurred over Yellowstone National Park on July 29, 1878. On June 8, 1918, in the midst of World War I, a total solar eclipse, dubbed the American Eclipse could be seen all across the United States. At 17 degrees Gemini, this eclipse conjoined the U.S. conceptional Mars (aggression) in the 7th house (foreign relations) as did an earlier eclipse in June, 1917 which occurred soon after the U.S. decision to enter the war. The Northwest was within the umbral shadow of the 1979 total solar eclipse. The next total solar eclipse to hit the mainland U.S.A. won't be until 2017.

Total Solar Eclipse Path (1918) — The following table delineates the path of the Moon's umbral shadow during the total solar eclipse of 1918 Jun 08. The geographic coordinates (WGS 84) of the northern and southern limits are listed, along with the central line. The path characteristics are generated at 1 minute intervals. This provides adequate detail for making plots of the path on larger scale maps. Local circumstances on the central line include the Sun's altitude and azimuth (degrees), the path width (kilometers) and the duration of the central eclipse (minutes and seconds). An orthographic map shows the global visibility of this eclipse. {Annular Solar Eclipse 03-Dec-1918}

Total Solar Eclipse Described by PlutarchNow, grant me that nothing that happens to the sun is so like its setting as a solar eclipse. You will, if you call to mind this conjunction recently which, beginning just after noonday, made many stars shine out from many parts of the sky and tempered the air in the manner of twilight. If you do not recall it, Theon here will cite us Mimnermus and Cydias and Archilochus and Stesichorus besides and Pindar, who during eclipses bewail "the brightest star bereft" and "at midday night falling" and say that the beam of the sun "<is sped> the path of shade".

Einstein timelineJun-1911 - realises solar eclipse could test general relativity by bending light from distant stars that passes close to the surface of the sun; 01-Aug-1914 - WWI begins; Nov-1914 - Signs antiwar manifesto. German colleagues are very patriotic, it was “like living in a madhouse.” Members of a German expedition to Russia are arrested and can’t measure the deflection of starlight in the solar eclipse, predicted by Einstein; 22-Sep-1919 - learns of success of May 29th’s solar eclipse results from Arthur Stanley Eddington’s expedition to Western Africa (Principe) and Brazil. The team had photographed stars near to the eclipsed sun and shown that their position was deflected by the amount predicted by general relativity. {Quantum theory & the Nobel prize}

space.com — In his autobiography "Starlight Nights," Leslie C. Peltier (1900-1980) wrote of his observation of a partial solar eclipse in June 1918. From his Delphos, Ohio home, the eclipse reached 75 percent coverage. When the eclipse reached its peak, Peltier wrote " . . . the nearby fields, the distant vistas, all seemed wrapped in some unearthly early twilight. The sky seemed darker - shadows faint and indistinct. A cool wind, almost chilly had sprung up from the west."
