1815 Beethoven (1932 CE1)          Discovered 1932-Jan-27 by Reinmuth, K. at Heidelberg
Discovery is clearly Jan. 27, although this object was originally thought to be planet 820. By error a provisional designation 1932 CE1 instead of a B designation was assigned.
Note: "planet" implies "minor planet"
