Class: PARALLAX. Held under continued observation.
Field notes: A field of circular forms of varying size distributed across the entire composition without visible ground plane or orienting structure. Approximately one-eighth of the circles are fully filled; the remainder are open. The density of circles increases from left to right across the field. The filled forms do not cluster according to any pattern the institution has been able to verify. The relationship to Observation 0021a has been noted but not resolved.
