Three-dimensional reconstruction of UV emissivities in the solar corona using Ultraviolet Coronagraph Spectrometer data from the Whole Sun Month

Abstract

UV coronal intensity data collected by the Ultraviolet Coronagraph Spectrometer on SOHO in a daily synoptic program during the Whole Sun Month are used to reconstruct the three-dimensional distribution of emissivities in the solar corona for H I Ly α and the O VI doublet at 1032 and 1037 Å. We discuss the specifics that complicate a tomographic reconstruction of the solar corona and estimate the uncertainties introduced in the reconstruction by them.
