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…
The ratio of horizontal to vertical displacement in solar oscillations estimated from combined SO/PHI and SDO/HMI observations
J. Schou, J. Hirzberger, D. Orozco Suárez +44
In order to make accurate inferences about the solar interior using helioseismology, it is essential to understand all the relevant physical effects on the observations. One effect…
The magnetic drivers of campfires seen by the Polarimetric and Helioseismic Imager (PHI) on Solar Orbiter
F. Kahil, J. Hirzberger, S. K. Solanki +56
The Extreme Ultraviolet Imager (EUI) on board the Solar Orbiter (SO) spacecraft observed small extreme ultraviolet (EUV) bursts, termed campfires, that have been proposed to be bri…
The Polarimetric and Helioseismic Imager on Solar Orbiter
S. K. Solanki, J. C. del Toro Iniesta, J. Woch +121
This paper describes the Polarimetric and Helioseismic Imager on the Solar Orbiter mission (SO/PHI), the first magnetograph and helioseismology instrument to observe the Sun from o…
The second flight of the SUNRISE balloon-borne solar observatory: overview of instrument updates, the flight, the data and first results
S. K. Solanki, T. L. Riethmüller, P. Barthol +32
The SUNRISE balloon-borne solar observatory, consisting of a 1~m aperture telescope that provided a stabilized image to a UV filter imager and an imaging vector polarimeter, carrie…
The Wave-Front Correction System for the Sunrise Balloon-Borne Solar Observatory
T. Berkefeld, W. Schmidt, D. Soltau +21
This paper describes the wave-front correction system developed for the Sunrise balloon telescope, and provides information about its in-flight performance. For the correction of l…
The Sunrise Mission
Peter Barthol, Achim Gandorfer, Sami K. Solanki +42
The first science flight of the balloon-borne \Sunrise telescope took place in June 2009 from ESRANGE (near Kiruna/Sweden) to Somerset Island in northern Canada. We describe the sc…
The Imaging Magnetograph eXperiment (IMaX) for the Sunrise balloon-borne solar observatory
V. Martinez Pillet, J. C. del Toro Iniesta, A. Alvarez-Herrero +39
The Imaging Magnetograph eXperiment (IMaX) is a spectropolarimeter built by four institutions in Spain that flew on board the Sunrise balloon-borne telesocope in June 2009 for almo…
The Filter Imager SuFI and the Image Stabilization and Light Distribution System ISLiD of the Sunrise Balloon-Borne Observatory: Instrument Description
A. Gandorfer, B. Grauf, P. Barthol +29
We describe the design of the Sunrise Filter Imager (SuFI) and the Image Stabilization and Light Distribution (ISLiD) unit onboard the Sunrise balloon borne solar observatory. This…
