Abstract

We inverted the symmetric part of the fine structure in the 1986 and 1988 solar oscillation data of Libbrecht and Woodard to find statistically significant evidence for a steady megagauss toroidal field at the bottom of the convective envelope. We confirm the sizable amplitude of a cycle-dependent near-surface perturbation which we argue has its origin in the fibril field.
