Nakano Note (Nakano wa Kangaeru noda) NK 4693 P/2022 C1 (PANSTARRS)
The following improved orbital elements, by S. Nakano, are from 58 observations 2021 Nov. 6 to 2022 Apr. 6. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.34 arc second. See the previous orbits in CBET 5096 and NK 4664. Epoch = 2021 Nov. 2.0 TT T = 2021 Nov. 4.64509 +/- 0.06539 (m.e.) TT Peri. = 9.38447 +/- 0.00976 Node = 113.14940 +/- 0.00057 (2000.0) Inc. = 4.76255 +/- 0.00011 q = 3.9856382 +/- 0.0000773 AU e = 0.4474514 +/- 0.0000166 a = 7.2131897 +/- 0.0002578 AU n' = 0.05087601 +/- 0.00000273 P = 19.373 +/- 0.0010387 years (+/- 0.38 day) The predicted orbit for the 2041 return is as follows: T = 2041 May 1.07680 TT Epoch = 2041 May 1.0 TT Peri. = 9.80406 e = 0.4481553 Node = 113.14555 (2000.0) a = 7.2238439 AU Inc. = 4.75994 n'= 0.05076350 q = 3.9864403 AU P = 19.416 years The following residuals in seconds of arc are from the above orbital elements: Date Code Residual(") Date Code Residual(") Date Code Residual(") 2021/ 220201 G96 0.1+ 0.1- 220228 215 0.1- 1.0+ 211106 F52 0.3+ 0.3- 220201 G96 0.3- 0.1- 220228 215 0.3- 0.8+ 211106 F52 0.5+ 0.2- 220201 G96 0.1- 0.1- 220228 215 0.8- 0.9+ 211106 F52 0.0 0.1+ 220201 G96 0.1+ 0.0 220302 F52 0.1+ 0.1- 211106 F52 0.1+ 0.4+ 220203 F52 0.1+ 0.2- 220302 F52 0.1+ 0.1+ 211107 F51 0.1- 0.1+ 220203 F52 0.2+ 0.2- 220302 F52 0.2+ 0.1- 211107 F51 0.1- 0.1+ 220203 F52 0.1+ 0.1- 220302 F52 0.2+ 0.1- 211107 F51 0.4- 0.2+ 220203 F52 0.2+ 0.1- 220308 867 0.1+ 0.1- 211110 F51 0.2+ 0.0 220203 F52 0.4+ 0.1- 220308 867 0.0 0.2- 211111 F51 0.0 0.1- 220203 F52 0.1+ 0.2- 220308 867 0.4- 0.6- 211111 F51 0.0 0.2+ 220209 F52 0.1+ 0.1- 220324 867 0.4+ 0.2+ 211111 F51 0.0 0.0 220209 F52 0.2+ 0.1- 220324 867 0.6+ 0.0 211111 F51 0.1- 0.1+ 220209 F52 0.0 0.0 220324 867 0.6+ 0.5- 2022/ 220209 F52 0.1+ 0.0 220324 867 1.0- 0.0 220108 F52 0.2+ 0.1- 220226 H06 0.4- 0.1+ 220404 867 0.2- 0.5+ 220108 F52 0.3- 0.1+ 220226 H06 0.5- 0.4+ 220404 867 0.2+ 0.1- 220126 G96 0.0 0.6- 220227 G96 0.1- 0.2+ 220404 867 0.4+ 0.0 220126 G96 0.2+ 0.4+ 220227 G96 0.0 0.5- 220404 867 0.4+ 0.2- 220126 G96 0.5- 0.1+ 220227 G96 0.1- 0.5- 220406 867 0.8- 0.7- 220126 G96 0.4- 0.1- 220227 G96 0.1+ 0.1- 220406 867 0.6+ 1.0+ ( ) -------- Rejected Obs.
