Overview of EUI/HRI and PHI/HRT observations from March 19, 2022: HRILyα image (left), HRIEUV image (middle) and HRT BLOS magnetogram (right) taken at 10:36:00 UT, 10:36:09 UT and 10:36:09 UT, respectively. The HRIEUV image is enhanced with the multiscale Gaussian normalization algorithm (Morgan & Druckmüller 2014). The numbers (same of Fig. 6) label the EUV bundles that have bright counterparts in the HRILyα image. Labels 1 and 2 have not been displayed since they are located outside the HRT FoV. The green (positive polarity) and cyan (negative polarity) contours enclose the regions where |BLOS|> 16.6 G. See more details in Section 3.2.
