3979 Brorsen           Discovered 1983 Nov. 8 by A. Mrkos at Klet.
Named in memory of Theodor Brorsen (1819-1895), Danish astronomer, known for his discoveries of five comets and his studies of the gegenschein. After studying and working in Kiel, Heidelberg and Altona he worked at the private observatory of baron John Parish in Senftenberg (Žamberk) in eastern Bohemia from 1847 to 1870. Name suggested by J. Ticha.
