Solar Physics in the era of ultra-high spatial resolution: Getting ready for DKIST
Daniel K. Inouye Solar Telescope: Overview and Status

National Solar Observatory
The 4m Daniel K. Inouye Solar Telescope (DKIST) currently under construction on Haleakala, Maui will be the world’s largest solar telescope. Designed to meet the needs of critical high resolution and high sensitivity spectral and polarimetric observations of the sun, this facility will perform key observations of our nearest star that matters most to humankind. DKIST’s superb resolution and sensitivity will enable astronomers to unravel many of the mysteries the Sun presents, including the origin of solar magnetism, the mechanisms of coronal heating and drivers of the solar wind, flares, coronal mass ejections and variability in solar output. The design allows the facility to observe over a broad wavelength range and enables DKIST to operate as a coronagraph and due to the photon flux provided by its large aperture will be capable of routine and precise measurements of the currently illusive coronal magnetic fields. The state-of-the-art adaptive optics system provides diffraction limited imaging and the ability to resolve features approximately 20 km on the Sun. Five first light instruments, representing a broad community effort, will be available at the start of operations: Visible Broadband Imager (VBI; National Solar Observatory), Visible SpectroPolarimeter (ViSP; High Altitude Observatory), Visible Tunable Filter (VTF; Kiepenheuer Institute, Germany), Diffraction Limited NIR Spectropolarimeter (DL-NIRSP; University of Hawaii) and the Cryogenic NIRSpectropolarimeter (Cryo-NIRSP; University of Hawaii). High speed cameras for capturing highly dynamic processes in the solar atmosphere are being developed by a UK consortium. Site construction on Haleakala began in December 2012 and is progressing on schedule. Operations are scheduled to begin in 2019. We provide an overview of the facility, discuss the construction status and present progress with DKIST operations planning.
