4/21 | Ueno | Multi-wavelength 2D Spectroscopy of the Solar Flare at δ-type Sunspot Region | At the ASJ Annual Meeting last month, I reported on results of the analysis of multi-wavelength spectroheliograph data (H-alpha, H-beta, H-gamma and CaII K) on the M-class flare that occurred on November 25, 2024 and a dark filament, plage around δ-type sunspot region (AR13906). However, since I couldn't make time for discussion at the ASJ meeting, I would like to introduce these analyses again in this Solar Seminar with adding some additional slides. | ||

Today, I would like to introduce following paper, Identifying Coronal Mass Ejection Active Region Sources: An Automated Approach Julio Hernandez Camero(1), Lucie M. Green(1), and Alex Pinel Neparidze(2) (1)Mullard Space Science Laboratory, University College London, UK (2)University College London, UK ApJ, 973, 63, 2025 https://ui.adsabs.harvard.edu/abs/2025ApJ...979...63H/abstract |

5/12 | Dai | End-view Observations of longitudinal oscillations of a quiescent prominence | Combining the Doppler velocities derived from the spectroscopic data provided by CHASE/HIS and SDO/AIA EUV data, we present the end-view Observations of longitudinal oscillations of a quiescent prominence, Based on the 3D velocity (values and directions) variations of the oscillation, we confirmed that the direction of the oscillations was longitudinal, and the geometry of the magnetic dip could be accurately described: the curvature radius of the magnetic dip was the smallest at its bottom and increased towards the sides, with a range of values of 87-258 Mm. Compared to the general pendulum model (Semicircular geometry), the calculations based on the variation of V3D are more realistic and accurate. | ||
