Time histories of 3 May 2023 M7 event. First panel (from the top): GOES X-rays flux. Second panel: Min-max normalized counts in SDO/AIA 304 Å channel. Third panel: Maximum in wavelength of the degree of linear polarization (black dots), absorption depth (blue dots), and maximum in wavelength of circular polarization (red dots) for He I D₃. The value of the maximum of the degree of linear polarization was computed according to Eq. (1) and similarly the values of the maximum in circular polarization are a fraction of I_c. Fourth panel: LOS bulk velocities inferred by HaZel with uncertainties.
