89/88, a.k.a. the sky comma, is an 89-limit superparticular comma tempered out by two of the Batch 89 temperaments. Tempering out this comma equates the harmonics 11/8 and 89/64.

Tempering this comma on its own gives the sky temperament, a 2.11.89 subgroup temperament.

It is very well approximated by 1 step of 36edf.
