The angle between a vector and the its projected vector onto a plane it intersects. More general, the angle between the vector and the "horizon" of the plane. This is the counterpart of the polar angle.
Solar altitude is the angular distance of the sun to the horizon from the view of an observer. Of course, every other heavenly body also has its altitude.
