ABSTRACT:
A radiation shadow indicator having a sight tube for sighting shadow-casting objects along a sighting axis. The indicator includes a system of gimbals mounting the tube for angular movement so that the sighting axis thereof may be caused to follow the apparent diurnal movement of celestial objects at various seasons of the year. Position indicators are provided for instantaneous read-out of angular positions of the gimbal device which, in turn, correspond to positions of the sighting axis at given seasons and/or times of day in relation to the location of the indicator on the surface of the earth.
