Abstract

Building on recent advances in coronal spectropolarimetry, seismology, and magnetic-field inferences of Z. Yang et al. (2024) and A. R. Paraschiv (2026), we present the first application of the CLEDB IQUD inversion methodology to Mauna Loa Solar Observatory CoMP and UCoMP observations. Using spectropolarimetric IQU measurements together with coronal seismology-derived magnetic field B POS constraints, we recover vector magnetic field solutions across the off-limb solar corona accessible to the observations, demonstrating the feasibility of routine large-scale coronal vector magnetometry without the need for Stokes V observations.
