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. 29 Planet 760. Independent discovery earlier the same night by G. Neujmin, Simeis. 30 Planet 793. Independent discovery Apr. 17 by J. H. Metcalf, Taunton, was announced first. 31 Planet 812. Independent discovery Sept. 11 by M.

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. 41 Planet 869. Independent discovery May 10 by M. Wolf, Heidelberg, was announced first. 42 Planet 878. and H. Shapley 43 Planet 882. Independent discovery Aug. 18 by M. Wolf, Heidelberg, was announced first. 44 Planet 883. Independent discovery earlier the same night by R. Schorr, Bergedorf. Both Wolf and Schorr initially thought the object was Encke's Comet, and Wolf was the first to realize that it was not. 45 Planet 885. Independent discovery Sept. 26 by M. Wolf, Heidelberg, was announced first. 46 Planet 886. Independent discovery Nov. 12 by M. Harwood, Nantucket. 47 Planet 887.

Independent discovery Dec. 14 by M. Wolf, Heidelberg, was announced first. 54 Planet 1004. Independent discovery Sept. 13 by K. Reinmuth, Heidelberg, was announced first. 55 Planet 1033. Independent discovery Sept. 5 by S. Belyavskij, Simeis, was announced first. 56 Planet 1051. Sept. 15, given by some authorities, refers to local mean time. 57 Planet 1057. Independent discovery Aug. 19 by K. Reinmuth, Heidelberg, was announced first. 58 Planet 1067. Sept. 10, given by some authorities, refers to the local meridian. 59 Planet 1090. Independent discovery Feb. 24 by K. Reinmuth, Heidelberg, was announced first. 60 Planets 1095, 1449. 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, Heidelberg, was announced first. 65 Planets 1125 and 3789. The original planet 1125 China was discovered 1928 Oct. 25 as 1928 UF by Y. C. Chang at Williams Bay and not observed again for many years. It was believed to have been recovered as 1957 UN1 on 1957 Oct. 30 by Chang at Nanking, but this identification was found to be incorrect. In agreement with the discoverer, the designation 1125 China was assigned to planet 1957 UN1. In 1986 C. M. Bardwell and S. Nakano independently identified 1986 QK1 with 1928 UF, and subsequently the permanent number 3789 was assigned to 1928 UF = 1986 QK1. 66 Planet 1137. Independent discovery Nov. 21 by K. Reinmuth, Heidelberg, was announced first. 67 Planet 1164. Independent discovery Mar. 20 by W. Baade, Bergedorf, was announced first. 68 Planet 1166. Independent discovery June 29 by K.

Neujmin found that planet 1317 = 1934 FD, discovered 1934 Mar. 19 by C. Jackson, Johannesburg (UO), is identical with 787 Moskva, discovered 1914 Apr. 20 by Neujmin. The number 1317 was later given to planet 1935 RC. 81 Planet 1323. Prediscovery observations exist as early as May 8. The May 19 discovery date quoted by some authorities in in error. 82 Planet 1335. Independent discovery Sept. 13 by E. Delporte, Uccle, was announced first. 83 Planet 1362. Discovery is clearly July 31. Preliminary designation is associated with the Aug. 27 observation. 84 Planet l363. Preliminary designation is assigned to the Sept. 3 observation. Discovery Aug. 30 was initially, and incorrectly, attributed to planet 1231. 85 Planet 1364. Discovery is clearly Nov. 18. By error the preliminary designation 1935 VB instead of a W designation was assigned. 86 Planet 1367. Independent discovery July 6 by K. Reinmuth, Heidelberg, was announced first. 87 Planet 1379.

Nov. 16 observation seems to be a prediscovery. 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 performed under the direction of T. Gehrels. During the years 1947-1967, in which the plates were 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. 105 Planet 1631. Observation 1926 Oct. 5 as 1926 TH by K. Reinmuth, Heidelberg, should be considered a 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 exposed 130 plates with the 122 cm Schmidt camera at Palomar. In the following years C. J. van Houten and I. van Houten-Groeneveld measured these plates astrometrically and photometrically at Leiden. P. Herget, Cincinnati, computed the orbits of the planets found on the NORC computer, Dahlgren, Virginia, USA. 108 Planet 1815. 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. 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, Leiden, on plates exposed by T.

Belyaiev 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. 119 Planets discovered at the Anderson Mesa station, which is operated by the Lowell Observatory. 120 Planet 2099. and E. M. Shoemaker 121 Planet 2104. on plates taken by S. van den Bergh. 122 Planet 2147. Oct. 24 observations should be considered a prediscovery. 123 on plates by E. F. Helin and S. J.
