GeocentricEarthEquatorial

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

Bases: sunpy.coordinates.frames.SunPyBaseCoordinateFrame

A coordinate or frame in the Geocentric Earth Equatorial (GEI) system.

  • The origin is the center of the Earth.

  • The Z-axis (+90 degrees latitude) is aligned with the Earth’s north pole.

  • The X-axis (0 degrees longitude and 0 degrees latitude) is aligned with the mean (not true) vernal equinox.

Parameters

Notes

Aberration due to Earth motion is not included.
