Solon Irving Bailey (December 29, 1854 – June 5, 1931) was an Americanastronomer and discoverer of the asteroid504 Cora, on June 30, 1902.^[1][2][3]

Bailey joined the staff ofHarvard College Observatory in 1887. He received a bachelor's and master's fromBoston University in 1881 and 1884, and a master's fromHarvard University in 1888.^[1] After the observatory received the "Boyden Fund" bequest from the will ofUriah A. Boyden, Bailey played a major role in finding a site for Boyden Station^[4] in Arequipa, Peru, and was in charge of it from 1892 to 1919. He was also one of the first to carry outmeteorological studies in Peru, traveling extensively in desolate areas at very high altitude. Boyden Station was moved toSouth Africa in 1927 due to better weather conditions and became known as theBoyden Observatory.^[5]

He made extensive studies ofvariable stars inglobular clusters in the southern skies. He also performed alight-curve analysis measuring the rotation period of the near-Earth asteroid433 Eros during its 1903 opposition.^[5] Bailey was acting director of Harvard College Observatory from 1919 to 1921 after the death ofEdward Charles Pickering and prior to the appointment ofHarlow Shapley. He worked as a senior colleague withHenrietta Leavitt.^[6] He was elected a Fellow of theAmerican Academy of Arts and Sciences in 1892.^[7] Irving died on June 5, 1931, aged 76, inHanover, New Hampshire, from an illness caused by heart disease.^{[8][9][10][11]}
