Named to honor Charlotte E. Moore (Mrs. Bancroft W. Sitterly) {1898–1990}, whose long-time collaboration with Henry Norris Russell {see planet  (1762)} included analyses of many atomic spectra and the important work on dynamical parallaxes that led to their landmark treatise, The masses of the stars, in 1940. She joined the staff of the U.S. National Bureau of Standards in 1945 and continued her work on atomic spectra of astrophysical interest. She served as president of IAU Commission 14 during 1961–1967. Her formal retirement in 1968 did not stop her activities, and she continues to be an international resource in this field. (M 8797) _ _.
