37853 Danielbarbier           Discovered 1998 Feb. 27 by E. W. Elst at the European Southern Observatory.
Daniel Barbier (1907-1965), a French observational astronomer, made significant contributions to the study of the background of the night sky. He turned his interest to the 6300 Å forbidden line of neutral oxygen by measuring the variations of its strength with the height in the ionosphere where it is emitted.
