BaseMagnetic#

class sunpy.coordinates.BaseMagnetic(*args, **kwargs)[source]#

Bases: SunPyBaseCoordinateFrame

Base class for frames that rely on the Earth’s magnetic model (MAG, SM, and GSM).

This class is not intended to be used directly and has no transformations defined.

Attributes Documentation

default_differential#: Default representation for differential data (e.g., velocity)

default_representation#: Default representation for position data

dipole_lonlat#

The geographic longitude/latitude of the Earth’s magnetic north pole.

This position is calculated from the first three coefficients of the selected IGRF model per Franz & Harper (2002). The small offset between dipole center and Earth center is ignored.

dipole_moment#

The Earth’s dipole moment.

The moment is calculated from the first three coefficients of the selected IGRF model per Franz & Harper (2002).
