Given a latitude of about 27o S we can - with the help of Lockyer - ascertain in which direction 'mother' points (i.e. presumably towards solstice):
She probably does not (I follow the logic of Lockyer) point up in the sky but towards a point on the horizon. Points on the horizon are defined by amplitude: "The amplitude of a body on the horizon is its distance north and south of the east and west points; it is always measured to the nearest of these two latter points, so that its greatest value can never exceed 90o. For instance, the south point itself would have an amplitude of 90o south of west (generally written W. 90o S.), or 90o south of east (E. 90o S.), while a point 2o to the westward of south would have an amplitude of W. 88o S., and not E. 92o S." Lockyer then delivers a diagram where the declination (height of a celestial body above the celestial equator) is converted to amplitude (depending on latitude of the observer). |
