Nakano Note (Nakano wa Kangaeru noda) NK 5614 P/2025 U1 (Hogan)
The following improved orbital elements, by S. Nakano, are from 89 observations 2025 Oct. 30 to 2026 May 12. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.36 arc second. See an orbit in CBET 5630. Epoch = 2026 Mar. 21.0 TT T = 2026 Mar. 25.91663 +/- 0.07028 (m.e.) TT Peri. = 264.04033 +/- 0.00938 Node = 234.93425 +/- 0.00023 (2000.0) Inc. = 23.82945 +/- 0.00004 q = 4.1659073 +/- 0.0000309 AU e = 0.2939058 +/- 0.0000063 a = 5.8999312 +/- 0.0000685 AU n' = 0.06877548 +/- 0.00000120 P = 14.331 +/- 0.0002493 years (+/- 0.09 day) The predicted orbit for the 2040 return is as follows: T = 2040 Apr. 30.06052 TT Epoch = 2040 May 6.0 TT Peri. = 262.76791 e = 0.2936385 Node = 234.64447 (2000.0) a = 5.8651023 AU Inc. = 23.84489 n'= 0.06938901 q = 4.1428824 AU P = 14.204 years The following residuals in seconds of arc are from the above orbital elements: Date Code Residual(") Date Code Residual(") Date Code Residual(") 2025/ 251127 F51 0.2+ 0.1+ 260225 F51 0.0 0.2- 251030 G96 0.2+ 0.1+ 251127 F51 0.1+ 0.0 260225 F51 0.1+ 0.1- 251030 G96 0.0 0.0 251127 F51 0.2+ 0.1+ 260225 F51 0.1+ 0.2- 251030 G96 0.2+ 0.1- 251127 F51 0.0 0.1- 260225 F51 0.1+ 0.1- 251030 G96 0.1+ 0.0 251217 F52 0.1+ 0.0 260225 F51 0.0 0.1- 251030 G96 0.2- 0.5+ 251217 F52 0.1+ 0.1- 260225 F51 0.2- 0.1- 251030 G96 0.2+ 0.2+ 251217 F52 0.2+ 0.0 260225 F51 0.0 0.0 251030 G96 0.2+ 0.3- 251217 F52 0.2+ 0.1+ 260226 L27 0.9+ 1.3- 251031 I52 0.6- 0.1+ 251226 X03 0.6- 0.4+ 260226 L27 0.3+ 0.2- 251031 I52 0.6- 0.1- 251226 X03 0.2- 0.5- 260226 L27 0.9+ 0.1+ 251031 I52 0.1- 0.6- 251226 X03 0.2+ 0.0 260311 M22 0.0 0.2+ 251101 I52 0.5+ 0.0 251228 F52 0.2+ 0.0 260311 M22 0.7+ 0.0 251101 I52 0.4- 0.1+ 251228 F52 0.0 0.1+ 260311 M22 0.5- 0.4- 251101 I52 0.6+ 0.5- 251228 F52 0.0 0.1- 260311 M22 0.3+ 0.1+ 251101 I52 0.6- 0.5+ 251228 F52 0.2+ 0.0 260319 215 0.3+ 0.5+ 251102 Q62 0.1- 0.1- 2026/ 260319 215 0.3+ 0.5+ 251102 Q62 0.1+ 0.2- 260118 G96 0.5- 0.5+ 260319 215 0.0 0.0 251103 I52 0.0 0.8- 260118 G96 0.8- 0.2+ 260320 G96 0.2+ 0.0 251103 I52 0.0 0.0 260118 G96 1.0- 0.8+ 260320 G96 0.3+ 0.0 251103 I52 0.7- 0.3+ 260118 G96 0.8- 0.8+ 260320 G96 0.5+ 0.1+ 251103 I52 0.1- 0.5- 260120 Q14 (3.5- 1.9-) 260320 G96 0.1+ 0.1+ 251104 I52 0.1- 0.1+ 260120 Q14 0.6- 0.9- 260412 W94 0.1+ 0.0 251104 I52 0.4+ 0.2- 260128 F52 0.0 0.1- 260412 W94 0.5+ 0.1+ 251104 I52 0.4- 0.1+ 260128 F52 0.1+ 0.0 260412 W94 0.8- 0.6+ 251104 I52 0.1- 0.4+ 260128 F52 0.1- 0.1- 260413 Q62 0.1+ 0.0 251119 215 0.3+ 0.3- 260128 F52 0.0 0.0 260413 Q62 0.1+ 0.2- 251119 215 0.2- 0.6+ 260217 F51 0.1+ 0.1- 260512 T08 0.6+ 0.5- 251119 215 0.7- 0.6+ 260217 F51 0.0 0.1- 260512 T08 0.2- 0.6+ 251123 F52 0.3+ 0.1- 260217 F51 0.2+ 0.1- 260512 T08 0.0 0.2- 251123 F52 0.3+ 0.1- 260217 F51 0.0 0.1- 260512 T08 0.8- 0.4- 251123 F52 0.2+ 0.1- 260225 F51 0.1+ 0.2- ( ) -------- Rejected Obs.
