An Erupting Solar Filament Observed at the DST
Abstract
An erupting filament that lead to a coronal mass ejection (CME) was observed at the Dunn Solar Telescope (DST). We present HAZEL inversions of spectropolarimetric observations of the 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 Daniel K. Inouye Solar Telescope (DKIST), future collaborations of the DKIST and the DST to study solar filaments are discussed.
