Complete original fictional account

An original invented three-dot star pattern is shown intact in fixed ground-frame R. Early on a fictional evening it is above the low rail at the right; later it is above the centre; still later above the left edge. Record W uses a newly moved frame V and says only “above centre”; no relation of V to R is given. Separately a marked unshaded Earth disk is turned against a stationary facing guide by the fictional model maker. No real constellation, compass direction, speed, latitude or actual local sky observation is supplied.
