Bitte aufpassen, im MPES sind noch nicht die neuen Bahnelementen (kann bei Delta T von über 4 d ganz schön in die Hose gehen). Es war wieder der schöne Effekt zu sehen, dass ein Komet von der PCCP (mit neuer Bahn) verschwindet, aber im MPES dann noch die alte steht! Zum Glück ist JPL Horizons immer ganz schnell auf dem neuesten Stand.

Gruß

Werner
