Das Spektrum des Vollmondes und seine Lichtfarbe
Der Vollmond ist bekanntlich kein Freund des Astronomen. Vielleicht ist das auch der Grund, weshalb sich heute kaum noch jemand mit seinem Licht befasst.
» In welchem Licht strahlt der Vollmond? (pdf)
Wer von dem obigen oder nachfolgenden Material Gebrauch machen möchte, sollte aus urheberrechtlichen oder wissenschaftlichen Gründen wie folgt zitieren: Dr. Lukas Schuler, Dark-Sky Switzerland, «In welchem Licht strahlt der Vollmond?» ORION 401 (2017), S. 14-18, ISSN0030-557 X
Im obigen Artikel wurde versprochen, dass die spektralen Daten von Sonne und Mond nach dem Erscheinen auf dieser Seite online zur Verfügung gestellt werden.
Das sei hiermit getan:
Spektrum der Sonne aus Abbildung 4 vom 27. Mai 2017 16:35 Uhr MESZ, Einzelmessung korrigiert für Remission auf Papier, Details siehe obigen Artikel.
Durchschnittliches, für die Transmission des Objektivs korrigiertes Spektrum des Vollmondes vom 11. Mai 2017 um 02h:33.5m ± 8.4 min MESZ, Details siehe Artikel, Abbildung 7 und Tabelle 3.
