All Authors: Theodosios Chatzistergos

Abstract: Because direct measurements of solar irradiance exist only from the late 1970s onward, models are required to reconstruct earlier irradiance variations. On...

All Authors: Milan Gosic

Abstract: The quiet regions of the solar surface are densely populated with small and weak magnetic flux patches. These patches contain an amount of magnetic flux comparable to what is found in active regions during the peak of the solar cycle. This suggests...

3. Probing the impact of viewing direction on the magnetic field evolution of an active region with SO/PHI and SDO/HMI

Last Name: Sinjan
Affiliation: Max Planck Institute for Solar System Research

All Authors: Jonas Sinjan, Johann Hirzberger, Daniele Calchetti, Gherardo Valori, Xiaohong Li, Sami K. Solanki and the PHI team

Abstract: Active regions are the source region for the most energetic phenomena on the Sun. Maps of active regions’ photospheric magnetic fields, and derived...
