Student-led Re-enactment of Eddington’s 1919 Light Deflection Test of General Relativity during the Great American Eclipse of 2017
We describe a student-led project to image two seventh-magnitude stars on either side of the Sun during the solar eclipse of August 21, 2017. Both stars were within one solar radius of the Sun, and according to Einstein’s theory of General Relativity, their positions would have been shifted away from the Sun by 1 arcsec. We observed the eclipse from three different sites along the path of totality (Lexington, South Carolina; Indian Valley, Idaho; Madras, Oregon). All three sites were clear, but the brightness of the solar corona has complicated the analysis. We present preliminary results using our best images from the site in Idaho.
