sunpy.sun.sun.apparent_declination(t='now', equinox_of_date=True) [edit on github]

Deprecated since version 1.0: The apparent_declination function is deprecated and may be removed in a future version. Use sunpy.coordinates.sun.apparent_declination instead.

Returns the Sun’s apparent declination relative to Earth, referred to the true equinox of date (as default). Corrections for nutation or aberration (for Earth motion) are included.
