A snapshot of solar activity through a Daystar Quark h-alpha filter (chromosphere version) on 14 June 2023. This is a mosaic image made from six separate panes, manually merged together. The chromospheric ‘surface’ has been inverted, a technique which helps provide a more three dimensional appearance to the elevated dark filaments that criss-cross the solar disc. Inverted, filaments appear lighter than the underlying chromosphere. The non-inverted version is shown below for comparison.
