Sunlight is reflected from the three mirror heliostat (upper left) to the 1.6 m concave mirror (lower right), then the 1.5 m mirror (center) to the observation room below.
The sun appears to be larger when rising or setting then when viewed overhead. This same effect is easier to see with the moon. Since neither the sun nor the moon is actually changing in size, there must be another explanation.
Why does the sun look larger at sunrise and sunset than at other times of the day?
