Reconstruction of total solar irradiance variability as simultaneously apparent from Solar Orbiter and Solar Dynamics Observatory

K. L. Yeo, N. A. Krivova, S. K. Solanki +42

Solar irradiance variability has been monitored almost exclusively from the Earth's perspective. {We present a method to combine the unprecedented observations of the photospheric…

Coronal voids and their magnetic nature

J. D. Nölke, S. K. Solanki, J. Hirzberger +68

Extreme ultraviolet (EUV) observations of the quiet solar atmosphere reveal extended regions of weak emission compared to the ambient quiescent corona. The magnetic nature of these…

Intensity contrast of solar network and faculae close to the solar limb, observed from two vantage points

K. Albert, N. A. Krivova, J. Hirzberger +43

The brightness of faculae and network depends on the angle at which they are observed and the magnetic flux density. Close to the limb, assessment of this relationship has until no…

Direct assessment of SDO/HMI helioseismology of active regions on the Sun's far side using SO/PHI magnetograms

D. Yang, L. Gizon, H. Barucq +47

Earth-side observations of solar p modes can be used to image and monitor magnetic activity on the Sun's far side. Here we use magnetograms of the far side obtained by the Polarime…
