The following improved orbital elements, by S. Nakano, are from 42 observations 2016 Jan. 3 to Feb. 10. The mean residual is +/- 0.66 arc second. Parabolic orbit shows original and future values of 1/a = around +0.000196 at origin and +0.000399 at future. The comet has passed 3.65 AU from Neptune on 2001 July 7 and 3.63 AU from Jupiter on 2015 Dec. 4 UT. T = 2015 Nov. 6.53557 +/- 0.01096 (m.e.)
