The reflection circle, a term coined here for the first time, is the circumcircle of the reflection triangle. It has center at Kimberling center 
, which is the 
-Ceva conjugate of 
.
The radius is given by

is the orthocenter,

is the area of the reference triangle, and

Its circle function interestingly corresponds to the same triangle center as its center:

Its 
-power is given by

No Kimberling centers lie on it. However, the anticomplements of 
and 
lie on it, as do the reflection of 
in 
and 
in 
(P. Moses, pers. comm., Jan. 31, 2005).
