Structural Invariance of Sunspot Umbrae Over the Solar Cycle: 1993-2004
Thomas A. Schad,M. J. Penn +1 more
TL;DR: In this article, the authors measured the maximum magnetic flux, minimum intensity, and size of 12 967 sunspot umbrae detected on the NASA/NSO spectromagnetograms between 1993 and 2004 to study umbral structure and strength during the solar cycle.

Inference of chromospheric magnetic fields in a sunspot derived from spectropolarimetry of Ca II 8542 A
TL;DR: In this paper, the authors analyzed spectropolarimetric observations of the chromospheric Ca II 8542 A line taken by the Interferometric Bidimensional Spectrometer (IBIS) at the Dunn Solar Telescope.

TL;DR: The Daniel K. Inouye Solar Telescope (DKIST) as mentioned in this paper , the largest solar telescope in the world, was constructed by the US National Science Foundation (NSF) and operates as a coronagraph at infrared wavelengths where the sky background is low and bright coronal emission lines are available.
