Glossary term: 日珥
Description: 日珥（prominences, 或filaments）是由於太陽周圍的磁場而形成的等離子體環。這些現象是暫時的，但可能會持續數周或數月，在日食期間經常可以拍到。一個典型的日珥延伸超過數千公里（km）；記錄中最大的日珥估計超過800,000公里長，大約是一個太陽半徑的長度。就像許多太陽現象一樣，人們也認為其他恆星也會展示出日珥現象。

H-alpha image of the Sun's chromosphere
Caption: 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.
