Abstract:	Supermoon estimation is prediction of the timing and distance of a perigee full or new moon. Some existing relevant tools can be opaque (lacking implementation details), functionally limited (giving a subset of the required information) or give mutually inconsistent results. A new supermoon estimator has been implemented to address drawbacks in, and to help benchmark, such existing tools. Specifically, the case of the 21st century supermoons is handled. Implementation in R is discussed, including time system transformations, numerical precision, general optimisations (e.g., Horner's scheme) and first-class function leveraging.
