About: Solar flux unit

An Entity of Type: software, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

The solar flux unit (sfu) is a convenient measure of spectral flux density often used in solar radio observations, such as the F10.7 solar activity index: 1 sfu = 104 Jy = 10−22 W⋅m−2⋅Hz−1 = 10−19 erg⋅s−1⋅cm−2⋅Hz−1. See jansky for further information about related units.

  • Die Solar Flux Unit (Einheitenzeichen: sfu) ist neben dem Jansky eine gebräuchliche Einheit der Radioastronomie für die spektrale Flussdichte und den solaren Flux: mit den Einheiten * W für Watt * Hz für Hertz * erg für Erg. (de)
