The structure and behavior of the magnetic canopy in the chromosphere is one of the great mysteries of the Sun. Previous works have indicated the existence of two components of the canopy: an inclined field that is the scaffolding for the fibrils observed in Hα, and a more vertical component that carries significant flux upward into the corona. Confirmation of these two components and detailed analysis of their structure and behavior is now becoming feasible, thanks to the unprecedented sensitivity and resolution of the NSF’s Daniel K. Inouye Solar Telescope (DKIST). We observe a fibril arcade emanating from a plage at high spatial resolution, using the Visible Spectropolarimeter Instrument (ViSP) to scan the fibrils and underlying supergranule in both the Fe I 6302 Å line and the Ca II 8542 Å line, with supplemental imaging from Visual Broadband Imager (VBI) in the Hβ, Ca II K, and G-band filters. Using these observations, we plan to perform spectropolarimetric inversions and search for the possible signature of this interlaced field in the quiet Sun canopy.
