1) first draw a horizontal line and a semicircle 2) from the center of the circle; and with respect to the horizontal line the solar height is drawn; the longitude and latitude. 3) a parallel to the latitude is drawn from the crossing of the solar altitude with the hemisphere; and is translated to trace a new semicircle (2). 4) divide the semicircle (2) into 12 equal parts; of 15º; corresponding to the hours of the day (round trip). 5) are drawn perpendicular to the new horizon line from the cut of the divisions of the circumference (2) with it. 6) from the center of both semicircles, paths are drawn perpendicular to the first horizontal line; to create a new system. now we have a sphere and a hemisphere (3). 7) the hemisphere (3) is divided in the same way that we have done with the hemisphere (2). 8) are drawn perpendicular to the new horizon lines from the point of intersection of the divisions with the hemisphere 9) we obtain the solar movement.
