 # Monatsvorschau TODO
 
-- Meteorstroeme aufnehmen: aktiver Zeitraum, Maximum, geschaetzte Stundenrate
 - Besonders enge Mond-Stern-Begegnungen heller Sterne ergaenzen, auch ohne Bedeckung
 - Helle Stern-/Planeten-Begegnungen aufnehmen, z. B. Venus nahe Regulus oder Mars nahe Spica
 - Mond nahe Plejaden und Mond nahe Praesepe als eigene Ereignisse pruefen
