R2.C(1/3)
Robert P. Munafo, 2010 Sep 20.
| R2-Name: | R2.C(1/3) |
| Abbrev: | R.C(3) |
| Colloq.: | Triple Spiral Valley |
| Coords: | center = -0.088 + 0.654i, size = 0. |
R2.C(1/3) is the R2-Name of the two cusps between R2a and R2.1/3a. The corresponding cusps near R2.2/3a are the same except for the vertical reflection.
The colloquial name "Triple Spiral Valley" comes from the triple spirals that are prominent in the filaments of the mu-atoms on the child side of the cusp. Features generally resemble those found in Seahorse valley but with one extra lobe on the parent side and an extra spiral arm on the child side.
See also R2.1/3.C(1/2).

In figure 1, the triple spirals are found near R2.1/3a in the upper part of the image. Each radical in the bottom part of the image has a shepherd crook and two more prominent spirals.
