Essential steps of the estimation method and a geometrical construct are<br \/>\ngiven to assist the visualization and calculation of the inclination angle. Measurements required<br \/>\nfor such an estimate are the arc lengths of the lunar and solar directions from the zenith direction<br \/>\nof an observer. The estimation method was actualized at the full Moon date that occurred about three<br \/>\nmonths after the full lunar eclipse in 2015.
