Finally, the sky had turned a discernible blue, and the pseudo-sun was clearly visible at an angle of perhaps ten degrees above the horizontal. It wasn’t a perfect illusion. For one thing, every point on the surface of the habitat would see the sun pass directly overhead, as if everyone was at the equator. For another, the swing across the sky wouldn’t be evenly paced. Because the pseudo-sun moved at a constant pace along the central cylinder, it would appear to accelerate as it approached local zenith, then slow down afterward. Noon would be very brief.
