Expand description

Calculate solar elongation for a celestial body.

Solar elongation is the angle between the lines of sight from the Earth to the Sun and from the Earth to the celestial body.

  • dec_min – Declination, minutes part
  • dec_sec – Declination, seconds part
  • gwdate_day – Greenwich Date, day part
  • gwdate_month – Greenwich Date, month part
  • gwdate_year – Greenwich Date, year part

§Returns

  • solar_elongation_deg – Solar elongation, in degrees
