25: 259: 130: 212:, however, the plates start to "wobble", causing their surfaces to deviate some degrees from the ideal horizontal orientation, and causing the reflection (i.e., the subsun) to become elongated vertically. When the deviation is sufficiently large, the subsun is stretched into a vertical column known as a lower 204:
