The following improved orbital elements, by S. Nakano, are from 37 observations 1983 June 14 to 1983 October 31. Pertur- bations by all nine planets were taken into account. The mean residual is +/- 1.25 arc seconds: Epoch = 1982 Nov. 7.0 ET T = 1982 Nov. 23.24194 +/- 0.01458 (m.e.) ET Peri. = 353.45584 +/- 0.01207 Node = 248.00115 +/- 0.00951 1950.0 Inc. = 14.09785 +/- 0.00378 q = 2.5102917 +/- 0.0005386 AU e = 0.3445714 +/- 0.0001209 a = 3.8300006 +/- 0.0004195 AU nß = 0.13149396 +/- 0.00002160 P = 7.495 +/- 0.001231 years (+/- 0.45 day) The extension orbit is from the above orbital elements: T = 1982 Nov. 22.65774 ET Epoch = 1985 May 15.0 ET Peri. = 353.40232 e = 0.3434244 Node = 248.00852 1950.0 a = 3.8263736 AU Inc. = 14.09868 nß= 0.13168097 q = 2.5123036 AU P = 7.485 years m1 = 7.9 (k=15) m2 = 12.8 (k=5) The residuals from the above orbit are as follows: Date/ UT R.A.
