My current heliocentric orbit solution (using Bill Gray's FindOrb software):

Orbital elements:  2018-017A
Perihelion 2018 Feb 4.052468 TT =  1:15:33 (JD 2458153.552468)
Epoch 2018 Mar  1.0 TT   Earth MOID: 0.0002

e   0.2564439           Incl.    1.08018
q   0.98605603          Q        1.66621482
P   1.53/557.79d

226 of 236 observations 2018 Feb. 8-13; mean residual 0".28

(I used epoch 1 March to make sure gravitational perturbation by the Earth-Moon
system is no longer an issue in the elements)
