A total solar eclipse occurred on August 21, 1914. 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. The totality of this eclipse was visible from northern Europe and Asia. It was the first of four total solar eclipses that would be seen from Sweden during the next 40 years.
Erwin Finlay-Freundlich led an expedition to Crimea in an attempt to verify the general relativity theory of Albert Einstein during this solar eclipse. However, World War I broke out and he was interned in Russia, unable to carry out the necessary measurements. William Wallace Campbell, from neutral America, was permitted to continue with his plans, but cloud cover obscured the eclipse.
Each member 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.
