1990·Amport, Hampshire

Where it was reported. With no photograph to show, the plate is the place: Amport, and every formation the archive holds around it. 1 other formations sit on this exact point, because their sources named the same place and gave no finer position. The dashed ring is how precise the fix is (±2,000 m at place confidence), drawn at its true size.

Reported 1990 at Amport, Hampshire. One archive recorded it, so nothing about it can be cross-checked.

Geometry

1 diagram file(s) on this page, of which 1 is a shared cropcirclecenter placeholder rather than a drawing of this formation. measured from the diagram itself, and experimental: the extractor's rotational order is right on 88.8 % of a 200-diagram hand-labelled set against a gate of 90 %, so read a number here beside the picture rather than instead of it.

diagram	rotational symmetry	elements	rings	mirror	fill
cc c782665e (placeholder: digest)	≈ continuous (concentric circles)	1	1	0.996	1.0049

Experimental, and marked ≈ wherever it appears. These numbers are read off a drawing, not off the field: the extractor's rotational order agrees with a hand-labelled set on 88.8 per cent of 200 diagrams against a gate of 90 per cent, its element count is within one on 97.5 per cent, and its ring count is not calibrated at all. Nothing in the analysis tree is derived from the rotational order while that gate is unmet.

Diagrams that look like these: cc c782665e— the nearest by perceptual hash. The whole archive is browsable by shape in the shape section, and this formation's own diagrams go straight into that grid: show them in the grid.
