Finding Charts

Magnitudes Graph m1 = 7.5 + 5 log d + 15 log r [ ,-225] ( - 2013 Aug. 14) m1 = 1.5 + 5 log d + 35 log r [-225, 160] (2013 Aug. 14 - 2014 Sept. 3) m1 = 9.3 + 5 log d + 15.0 log r [ 160, ] (2014 Sept. 3 - )

The orbital elements are published at the MPC Ephemerides and Orbital Elements. The charts are made with StellaNavigator Ver.8 (AstroArts). The magnitudes graphs are made with Comet for Windows.
