Orbital Elements Perturbed ephemeris below is based on elements from MPC 54170. Epoch (TT/JD) T (TT/JD) Peri. Node Incl. 2457920.50000 2457916.9354190 162.03252 285.29338 5.02865 e q a Epoch (TT) 0.2115884 3.2972338 4.18212 2017/06/16.00

Magnitudes Graph m1 = 14.5 + 5 log d + 10.0 log r * Gray curve is: m1 = 5.5 + 5 log d + 20 log r

The orbital elements are calculated using the Minor Planet & Comet Ephemeris Service. The magnitudes graphs are made with Comet for Windows.
