Analyses on Christoph Clavius' Reports of Total Solar Eclipses in 1560 and 1567: Key References for the Centennial Variations of the Earth's Rotation Speed and the Solar Radius
Hisashi Hayakawa, Mitsuru Sôma, Jean-Pierre Rozelot +4
Variations in solar radius (hereafter R_Sun) is a key reference for solar magnetic activity in time. The sunlight amount may have varied with R_Sun and had an effect on the Earth's…

UK White Paper on Space-based total solar eclipse observations: structure and dynamics of the solar atmosphere
Lucie M. Green, Nicola Baresi, Huw Morgan +19
Our Sun is uniquely placed to enable a detailed study of astrophysical plasmas and how they are governed by the magnetic fields that thread through them. On the one hand, magnetic…

Linking Critical Heights in Solar Active Regions with 3D CME Speeds: Insights from Automated and Manual PIL Detection Methods
Harshita Gandhi, Alexander James, Huw Morgan +1
In a space weather context, the most geoeffective coronal mass ejections (CMEs) are fast CMEs from Earth-facing solar active regions. These CMEs are difficult to characterize in co…
