14872 Hoher List           Discovered 1990 Oct. 23 by E. W. Elst at Hoher List.
The Observatory of Hoher List, in the Ardennes near Daun (Eifel), was established in 1957 by the University of Bonn since light pollution had precluded astronomical observations at the Alte Sternwarte on Poppelsdorfer Allee.
