Finding Charts

Magnitudes Graph Primary Component: m1 = -7.5 + 5 log d + 100 log r(t + 70) * Gray curve is: m1 = 10.0 + 5 log d + 15.0 log r Component D: m1 = 12.0 + 5 log d + 30.0 log r [ ,0] ( - 2015 Aug. 12) m1 = 15.5 + 5 log d + 15.0 log r [0, ] (2015 Aug. 12 - )

The orbital elements are published on M.P.E.C. 2015-K139. The orbital elements of component D are published on M.P.E.C. 2015-L08. The charts are made with StellaNavigator Ver.8 (AstroArts). The magnitudes graphs are made with Comet for Windows.
