Nakano Note (Nakano wa Kangaeru noda) NK 3140 P/2015 B1 (PANSTARRS)
The following improved orbital elements, by T. Kobayashi, are from 90 observations 2014 Nov. 30 to 2016 Mar. 4. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.31 arc second. See the previous orbit in NK 2913 (= HICQ 2015). Epoch = 2015 Sept.15.0 TT T = 2015 Sept.21.65380 +/- 0.04074 (m.e.) TT Peri. = 188.42280 +/- 0.00317 Node = 353.35583 +/- 0.00004 (2000.0) Inc. = 18.03805 +/- 0.00008 q = 5.9750676 +/- 0.0000095 AU e = 0.3807438 +/- 0.0000070 a = 9.6487810 +/- 0.0001106 AU n' = 0.03288482 +/- 0.00000056 P = 29.972 +/- 0.0005167 years (+/- 0.19 day) The predicted orbit for the 2044 return is as follows: T = 2044 Nov. 15.68273 TT Epoch = 2044 Nov. 1.0 TT Peri. = 189.06482 e = 0.3648733 Node = 352.83593 (2000.0) a = 9.4395163 AU Inc. = 18.09447 n'= 0.03398439 q = 5.9952893 AU P = 29.002 years The following residuals in seconds of arc are from the above orbital elements: Date Code Residual(") Date Code Residual(") Date Code Residual(") 2014/ 150210 Q62 0.2+ 0.2+ 150324 D29 0.2- 0.6+ 141130 F51 0.0 0.2- 150210 Q62 0.2+ 0.7+ 150324 D29 0.1+ 0.0 141130 F51 0.1+ 0.1- 150214 461 0.5+ 0.1- 150325 F51 0.0 0.4- 141130 F51 0.0 0.1- 150214 461 0.2- 0.2+ 150325 F51 0.0 0.3- 141130 F51 0.1+ 0.0 150214 461 0.2- 0.2+ 150325 F51 0.1+ 0.3- 141209 F51 0.0 0.1- 150216 G45 0.4- 0.3+ 150325 F51 0.2+ 0.5- 141209 F51 0.2+ 0.1+ 150216 G45 0.5- 0.3+ 150327 568 0.0 0.3- 141209 F51 0.0 0.3+ 150216 G45 0.1- 0.3+ 150327 568 0.0 0.4- 141209 F51 0.1+ 0.2+ 150216 G45 0.6- 0.5- 150327 568 0.0 0.3- 141210 F51 0.1- 0.1- 150220 B74 0.4- 0.3+ 150327 568 0.1- 0.3- 2015/ 150220 B74 0.4- 0.2+ 150407 I93 0.9+ 0.6+ 150119 F51 0.2+ 0.1- 150220 B74 0.8- 0.1+ 150407 I93 0.7- 0.2+ 150119 F51 0.3+ 0.2- 150224 372 0.5- 0.3- 150411 G96 0.3+ 0.3+ 150119 F51 0.1+ 0.3+ 150224 372 0.3- 0.6- 150411 G96 0.1+ 0.7+ 150119 F51 0.1+ 0.0 150224 372 0.4+ 0.5- 150411 G96 0.0 0.6+ 150121 F51 0.3+ 0.1+ 150309 G96 0.2- 0.2+ 150411 G96 0.1+ 0.5+ 150121 F51 0.1+ 0.1- 150309 G96 0.1- 0.2+ 150416 568 0.1+ 0.2- 150121 F51 0.1- 0.5- 150309 G96 0.1+ 0.1+ 150416 568 0.1- 0.2- 150121 F51 0.1+ 0.0 150309 G96 0.1- 0.1+ 150416 568 0.1+ 0.3- 150129 F51 0.1+ 0.0 150311 D29 0.4+ 0.3- 150416 568 0.1+ 0.2- 150129 F51 0.1- 0.2- 150311 D29 0.7+ 0.1+ 150416 568 0.0 0.2- 150129 F51 0.3+ 0.4- 150311 D29 0.5- 0.9+ 150416 568 0.0 0.2- 150129 F51 0.3- 0.4- 150311 B74 0.5- 0.6+ 150422 F51 0.5+ 0.3- 150131 F51 0.5+ 0.2- 150311 B74 0.4- 0.2+ 150422 F51 0.0 0.1- 150131 F51 0.4+ 0.2- 150311 B74 0.2- 0.1- 150422 F51 0.6+ 0.4- 150131 F51 0.6+ 0.0 150314 F51 0.0 0.2- 150422 F51 0.2+ 0.4- 150131 F51 0.1+ 0.2- 150314 F51 0.2- 0.2- 2016/ 150210 691 0.1- 0.0 150319 215 0.5- 0.5+ 160304 F51 0.1- 0.1- 150210 691 0.2- 0.3+ 150319 215 0.7- 0.5+ 160304 F51 0.2- 0.2- 150210 691 0.3- 0.1- 150319 215 0.2- 0.1+ 160304 F51 0.0 0.1+ 150210 Q62 0.1+ 0.0 150324 D29 0.4+ 0.2+ 160304 F51 0.3+ 0.1+ ( ) -------- Rejected Obs.
