1095 Tulipa (1926 GS)          Discovered 1926-Apr-14 by Reinmuth, K. at Heidelberg
In 1966 C. Bardwell, Cincinnati, discovered that minor planet 1928 DC, discovered 1928 Feb. 24 by K. Reinmuth and originally designated 1095 Tulipa, is identical with planet 1449 Virtanen, discovered by Y. Vaisala, Turku, 1938 Feb. 20. This planet retains the latter designation 1449 Virtanen. The designation 1095 Tulipa has been reassigned to planet 1926 GS, discovered 1926 Apr. 14 by K. Reinmuth and newly catalogued.
Note: "planet" implies "minor planet"
