Filament Magnetic Fields at the DST and DKIST
Abstract
Observations from the 0.8-m Dunn Solar Telescope (DST) are qualitatively similar to data that will be produced by the 4-m Daniel K. Inouye Solar Telescope (DKIST), albeit at a lower spatial resolution and polarimetric sensitivity. We present HAZEL inversions of spectropolarimetric observations of a quiescent filament acquired with the Facility Infrared Spectropolarimeter at the DST. This study includes three observations of the He I triplet at 10830 Å on May 29 and 30, 2017. The filament was stable on May 29, and was observed in the process of rising at speeds of 20-30 km/s during the two spatial maps taken on May 30. Vector magnetic fields along the filament were obtained that show an inverse configuration indicative of a flux rope topology, including co-aligned threads. To take advantage of the better spatial and temporal resolution of the DKIST, future collaborations of the DKIST and the DST to study solar filaments are discussed. We propose to further study the evolution of solar filaments that erupt and lead to Coronal Mass Ejections using interspaced observations from the DKIST and DST spectropolarimeters. While the DST observations will give information about the global evolution of physical properties leading to the destabilization, the DKIST observations will provide the information about the physical conditions in the small-scale structures that support the filament material.
