- NOTES TO DISCOVERY CIRCUMSTANCES
-
- 1 Planet 9. Apr. 26 is date of first measurement.
- 2 Planet 20. Independent discovery the next night by J. Chacornac, Marseille, was announced first.
- 3 Planet 50. Independent discovery Oct. 19 by R. Luther, Dusseldorf, was announced first.
- 4 Planet 66. Apr. 10, given by some authorities, is the civil date.
- 5 Planet 69. Apr. 29 is date of first measurement.
- 6 Planet 71. Aug. 14 is date of first measurement.
- 7 Planet 80. May 3 is date of first measurement.
- 8 Planet 100. Independent discovery July 18 by C. Wolf, Paris, was announced first.
- 9 Planets discovered by Prosper and Paul Henry. In their cooperative program it will probably never
- be known which of the Henry brothers discovered which planet. With strict impartiality, these
- discoveries were announced as having been made alternatively by Prosper and by Paul.
- 10 Planet 154. Initial announcement gave Nov. 6.
- 11 Planet 179. Initial announcement gave Nov. 12.
- 12 Planet 220. Initial announcement gave May 18.
- 13 Planet 264. Discovery possibly as early as Dec. l7.
- 14 Planet 268. June 9 is date of first measurement.
- 15 Planet 323. Dec. 20 observation seems to be a prediscovery.
- 16 Planet 330. This planet was alleged to have been discovered 1892 Mar. 18 by M. Wolf at Heidelberg
- with the provisional designation 1892 X. Only one more position Mar. 20 was obtained, and from the
- resulting circular elements this object was never observed again. In 1982 R. M. West, C. Madsen,
- and L. D. Schmadel showed that these observations refer to galactic stars, and that 1892 X does not
- exist. Later in that year the designation 330 Adalberta was assigned to planet A910 CB, which had
- earlier been incorrectly identified with 783 Nora, and now newly numbered.
- 17 Planet 433. Independent discovery earlier the same night by A. Charlois, Nice.
- 18 Planet 457. Discovery telegram gave only Sept. 16 observation.
- 19 Planet 468. Already photographed on Jan. 13; it is not clear whether this should be regarded as a
- prediscovery image.
- 20 Planet 47l. May 18 prediscovery observation by L. Carnera is in error.
- 21 Planets 525, 1171. The original planet 525 Adelaide, discovered 1904 Mar. 14 by M. Wolf, Heidelberg,
- was observed only during the discovery opposition. In 1958 A. Patry, Nice, found that this object is
- identical with planet 1171 Rusthawelia, discovered 1930 Oct. 3 by S. Arend, Uccle. This planet
- retains the latter designation 1171 Rusthawelia. The older designation 525 Adelaide has been given
- to a minor planet discovered 1908 Oct. 21 by J. H. Metcalf and newly catalogued.
- 22 Planet 535. May 9, given by some authorities, is erroneous.
- 23 Planet 602. Independent discovery Feb. 22 by A. Kopff, Heidelberg, was announced first.
- 24 Planet 673. Independent discovery Sept. 21 by A. Kopff, Heidelberg, was announced first.
- 25 Planet 694. Independent discovery Nov. 9 by J. Helffrich, Heidelberg, was announced first.
- 26 Planets 699, 700. June 3, given by some authorities, is erroneous.
- 27 Planets 715, 933. The original planet 715 Transvaalia, discovered 1911 Apr. 22 by H. E. Wood, was
- recovered on 1920 Apr. 23 as 1920 GZ and given the designation 933 Susi. The identity was
- discovered in 1928 and the older designation 715 Transvaalia was retained. In the same year the
- designation 933 Susi was assigned to a newly-discovered planet.
- 28 Planets 758, 790. and K. Van der Spuy.

- Wolf, Heidelberg, is identical with 1078 Mentha, discovered 1926 Dec. 7 by K. Reinmuth, Heidelberg.
- This object retains the latter designation 1078 Mentha. In 1974 the designation 864 Aase was
- assigned to planet 1921 KE, discovered 1921 Sept. 30 by K. Reinmuth and newly catalogued.

- planet 1449 Virtanen, discovered by Y. Vaisala, Turku, 1938 Feb. 20. This planet retains the latter

- Williams Bay, has not been observed since its discovery opposition. It was believed to have been
- recovered as 1957 UN1 on 1957 Oct. 30 by Chang at Nanking, but this identity is now known to be

- 83 Planet 1362. Discovery is clearly July 31. Preliminary designation is associated with the Aug. 27
- observation.

- initially, and incorrectly, attributed to planet 1231.
- 85 Planet 1364. Discovery is clearly Nov. l8. By error the preliminary designation 1935 VB instead of

- 103. Planets discovered by the Indiana Asteroid Program, Goethe Link Observatory, University of Indiana.
- This program was conceived and directed by F. K. Edmondson, the plates were blinked and measured
- astrometrically by B. Potter and, following her retirement, by D. Owings, and the photometry was

- exposed a large number of people participated in various aspects of the program.
- 104 Planet 1608. Observation Aug. 25 by C. Rogati, La Plata, should be considered a prediscovery.

- prediscovery.
- 106 Planet 1674. Provisional designation is associated with an independent discovery Feb. 22 by Y.
- Vaisala, Turku, which was announced first. A third independent discovery earlier on Feb. 22 was
- made by G. Kulin, Budapest.
- 107. These planets have all been discovered as a result of the Palomar survey of faint minor planets and
- subsequently identified with planets observed at other oppositions. In Sept. and Oct. 1960 T. Gehrels

- 109 Planet 1850. Discovery is clearly Mar. 23. By error a provisional designation 1942 EN rather than
- an F designation was assigned.
- 110 Planet 1864. First measurement Mar. 26.
- 111 Planets 1870-1873, 1877. Planets discovered by C. J. van Houten and I. van Houten-Groeneveld,

- 117 Planet 2013. on exposures by J. Petit
- 118 Planet 2043. The Nov. 12 discovery observation was originally thought to refer to 1936 TG. By
- error the provisional designation was changed to 1936 TH instead of a V designation.
