The NASA Global-scale Observations of the Limb and Disk (GOLD) mission is a dual-channel imaging spectrograph that will be carried on a commercial communications satellite in geostationary orbit. Launch is scheduled for January, 2018.
Magnetism defines the complex and dynamic solar corona. It determines the magnetic loop structure that dominates images of the corona, and stores the energy necessary to drive coronal eruptive phenomena and flare explosions.
Observational solar physics is entering a new era with the advent of new 1.5 m class telescopes with adaptive optics, as well as the Daniel K. Inouye 4 m telescope which will become operational in 2019. Major outstanding problems in solar physics all relate to the solar magnetic field.
Art Richmond was awarded the 2017 Coupling Energetic Dynamics Atmospheric Research (CEDAR) Distinguished lecture for his fundamental contributions to upper atmosphere and ionosphere science over several decades.

We consider the observational basis for the belief that flare ribbons in the chromosphere result from energy transport from the overlying corona. We study ribbons of modest flares using magnetic as well as intensity data from the Hinode, SDO and IRIS missions.
We study UV spectra obtained with the SO82-B slit spectrograph on board SKYLAB to estimate the fine structure splitting of the Cl-like 3p43d4D5/2 and 3p43d4D7/2 levels of Fe X.
