Wodurch entstehen diese Sternbedeckungen?
Der Mond, Sterne und Planeten wandern durch die Erddrehung scheinbar von Osten nach Westen. Tatsächlich kreist der Mond in 27,321 Tagen um die Erde in gleicher Richtung wie die Erdrotation - von Westen nach Osten. Diese Eigenbewegung des Mondes führt zu einer laufenden Verschiebung der Mondposition vor dem Sternenhimmel in Richtung Osten. Diese Verschiebung beträgt etwa einen ganzen Vollmonddurchmesser (0.5 Grad) pro Stunde. Durch diese Wanderung des Mondes vor dem Sternenhintergrund nach Osten, kommt es laufend zu Sternbedeckungen des Mondes. Die Bedeckung von Planeten erfolgt aufgrund der geringeren Planetenanzahl natürlich viel seltener.

Die folgende Tabelle führt nur helle Objekte deren Bedeckung oder Hervortreten bereits im Fernglas oder kleinem Fernrohr ab 50 Millimeter Öffnung beobachtbar sein sollte. Es werden nur Ereignisse angeführt, die auch am Waldviertler Nachthimmel und dabei über dem Horizont stattfinden.

Erklärungen zu der Tabelle

day     : Datum in der Form Jahr-Monat-Tag
Time    : Weltzeit UTC in der Form Stunde-Minute-Sekunde (MEZ=UTC+1)
P       : D, d = Beginn einer Bedeckung
          R, r = Ende einer Bedeckung
          Gr, gr = streifende Bedeckung durch Mondberge
Star    : Bezeichnung des bedeckten Sternes oder die Planetenbezeichnung
Sp      : Spektralklasse des bedeckten Sternes
Mag     : Helligkeitsangabe zum bedeckten Objekt. Je heller ein Objekt erscheint,
          desto kleiner bis sogar negativ ist der Mag-Wert
%       : Prozent der Mondbeleuchtung dabei steht +/- für zunehmend/abnehmend
Elon    : Winkelabstand des Mondes zur Sonne
Sun/Alt : Sonnenhöhe, aber nur angegeben wenn Sonne höher als -12 Grad steht
Moon/Alt: Mondhöhe über dem Horizont
Moon/Az : Himmelsrichtung der Mondposition (Nord=0 oder 360, Ost=90, Süd=180, West=270)
CA      : Cusp Angel, Winkel um den Mondrand, gemessen vom Stern zur nächsten hellen Spitze
PA      : Position Angel, Winkel um den Mondrand, gemessen vom Stern zum wahren Nordpunkt
VA      : Vertex Angel, Winkel um den Mond, gemessen vom Stern zum höchsten Mondrandpunkt
AA      : Axis Angle , Winkel um den Mond, gemessen vom Mondnordpol ostwärts zum Stern

TIPP: Suchen Sie bei einem Bedeckungsbeginn das Objekt mit einem Fernglas schon etwa 15 Minuten
      in der Nähe des östlichen Mondrandes. Bei einem Bedeckungsende sollte man am westlichen
      Mondrand nach dem auftauchenden Objekt suchen.
