F. W. Dyson, A. S. Eddington, and C. Davidson, "A Determination of the Deflection of Light by the Sun's Gravitational Field, from Observations Made at the Total Eclipse of May 29, 1919" Philosophical Transactions of the Royal Society of London. Series A, Containing Papers of a Mathematical or Physical Character (1920): 291-333, on 332.


Read "Eclipses and Relativity: Testing Einstein's Theory of Gravity," a short report prepared by NASA that discusses an astronomer's observations of the 1919 total solar eclipse on May 29th from the west coast of Africa. 

Do you want to use your phone to take a photo of the eclipse on August 21st?  If so, read this article first from August 1st of The Washington Post by Wendy Galietta and Angle Fritz.

Do you have more questions about the upcoming eclipse?
