This false-color image was captured with a 10-cm telescope at the Big Bear Solar Observatory (BBSO) in the United States in July 2002. It depicts the full disk of the Sun using the H-alpha emission line of hydrogen. When observed in this spectral line, the Sun's chromosphere appears particularly prominent due to hydrogen atoms emitting light at the specific wavelength. This emission produces a distinctive red color, making features such as spicules (jets of plasma that look hair-like) and plage (bright patches in the chromosphere) highly visible. Several small solar prominences can be seen protruding from the edge of the solar disk. When prominences (also known as filaments) cross the face of the disk they appear as dark threads caused by the cooler material in the prominence absorbing light. The chromosphere is also visible in the violet part of the solar spectrum due to ionized calcium showing emissions in these wavelengths.

图片说明 Dieses Falschfarbenbild wurde mit einem 10-cm-Teleskop am Big Bear Solar Observatory (BBSO) in den Vereinigten Staaten im Juli 2002 aufgenommen. Es zeigt die gesamte Sonnenscheibe in der H-alpha-Emissionslinie des Wasserstoffs. Bei der Beobachtung in dieser Spektrallinie erscheint die Chromosphäre der Sonne besonders auffällig, da Wasserstoffatome bei dieser Wellenlänge Licht emittieren. Diese Emission erzeugt eine charakteristische rote Farbe, die Merkmale wie Spikulen (haarähnliche Plasmastrahlen) und Sonnenfackeln (helle Flecken in der Chromosphäre) gut sichtbar macht. Mehrere kleine Sonnenerhebungen sind zu sehen, die aus dem Rand der Sonnenscheibe herausragen. Wenn Protuberanzen (auch Filamente genannt) die Oberfläche der Sonnenscheibe kreuzen, erscheinen sie als dunkle Fäden, die durch das kühlere Material in der Protuberanz verursacht werden, das Licht absorbiert. Die Chromosphäre ist auch im violetten Teil des Sonnenspektrums sichtbar, da ionisiertes Kalzium in diesen Wellenlängen emittiert.

图片说明 Questa immagine in falsi colori è stata acquisita con un telescopio da 10 cm presso il Big Bear Solar Observatory (BBSO) negli Stati Uniti nel luglio 2002. Raffigura l'intero disco del Sole utilizzando la linea di emissione H-alfa dell'idrogeno. Quando viene osservata in questa linea spettrale, la cromosfera del Sole appare particolarmente evidente a causa degli atomi di idrogeno che emettono luce a quella specifica lunghezza d'onda. Questa emissione produce un caratteristico colore rosso, rendendo altamente visibili caratteristiche come le spicole (getti di plasma che sembrano capelli) e le facule (macchie luminose nella cromosfera). È possibile osservare diverse piccole protuberanze solari che sporgono dal bordo del disco solare. Quando le protuberanze (note anche come filamenti) attraversano la faccia del disco, appaiono come fili scuri causati dal materiale più freddo della protuberanza che assorbe la luce. La cromosfera è visibile anche nella parte violetta dello spettro solare a causa del calcio ionizzato che mostra emissioni in queste lunghezze d'onda.
