It is early in the second Apollo 12 EVA. Al is still in the LM.
131:42:48 Conrad: Oh, my friendly gnomon. In all the (garbled)
activity yesterday, I forgot all about him sitting here.
Editor's Note: The gnomon consists of a free-swinging vertical rod mounted in a three-legged stand. One of the legs also has a color chart and gray scale. When taking documentation photographs of the geology samples, they will place the gnomon in the field-of-view with the color chart/grey scale in sunlight. The
gnomon staff shows local vertical and also provides a length scale.
