We analyzed the mechanisms of the penumbra and the curled light bridge by utilizing the SIR (Stokes Inversion based on
Response functions) inversion program. The magnetic field strength, LOS (line of sight) velocity, and inclination were the
main focus of both stratifications. The research on the penumbra was to compare the data with the siphon flow model and
interchange convection model. From analyzing the data, pertaining to the penumbra, we concluded both models gave a logical
representation of the penumbral mechanism. The light bridge system was under investigation for comparison to the cluster
model. There is no definite answer, however with our data collection we concluded the cluster model gave a good theory on
the mechanism of the light bridge.
