Extended context for the MiHI observations of 24 August 2018. Panels a–c show the emergence of AR12720 in HMI B_LOS magnetic field maps over a period of 48 h. Panel b has the approximate locations of the FOVs of MiHI marked in green and of the context imager in red. Panel d shows an IRIS raster map at the nominal wavelength of Mg II k observed 24 h after the MiHI observations. In the bottom row, the MiHI Hα wideband context image in panel f is accompanied by the closest available SDO images: HMI continuum (e), AIA 1700 Å (g), and AIA 304 Å (h).
