24858 Diethelm           Discovered 1996 Jan. 21 by M. Wolf and P. Pravec at Ondřejov.
Roger Diethelm (b. 1948) is a Swiss observer of variable stars and editor of the variable-stars bulletin of the Schweizerische Astronomische Gesellschaft. He founded the R. Szafraniec Observatory in Metzerlen, where the first of the discoverers observed on several occasions.
