Volker Bothmer acknowledges support of the projects CGAUSS (Coronagraphic German And US SolarProbePlus Survey) for the NASA Solar Probe Plus mission and Stereo/Corona for the NASA STEREO mission by the German Bundesministerium for Bildung und Forschung through the deutsche Zentrum für Luft- und Raumfahrt e.V. (DLR, German Space Agency) under grants 50OL1201 and 50 °C 0904. Stereo/Corona is a science and hardware contribution, carried out in collaboration with the Max-Planck-Institute for Solar System Research in Katlenburg-Lindau and the University of Kiel, to the optical image package SECCHI, developed for the NASA STEREO mission. CGAUSS is a science and hardware contribution to the WISPR (Wide-field Imager for Solar PRobe) imager for the NASA Solar Probe Plus mission.

The research studies carried out by Adam Pluta and Niclas Mrotzek in the framework of their Ph.D. theses have received funding from the EU FP7 grant agreement No 606692 HELCATS project and the EU FP7 grant agreement No 263506 AFFECTS project. The STEREO/SECCHI data used for this study are prepared by an international consortium of NASA Goddard Space Flight Center (USA), Lockheed Martin Solar and Astrophysics Lab (USA), Naval Research Laboratory (USA), Rutherford Appleton Laboratory (UK), University of Birmingham (UK), Max-Planck-Institut für Sonnensystemforschung (Germany), Institut d'Optique Theorique et Appliquee (France), Institut d'Astrophysique Spatiale (France) and Centre Spatiale de Liege (Belgium). The NRL effort was supported by NASA, the USAF Space Test Program and the Office of Naval Research. The work of Angelos Vourlidas and Russell A. Howard is supported by NASA contract S-136361-Y to the Naval Research Laboratory. Data from the SOHO/MDI instrument are courtesy of the SOHO/MDI consortium. The SOHO/MDI data are produced by an international consortium of the Naval Research Laboratory (USA), Max-Planck-Institut für Aeronomie (Germany), Laboratoire d'Astronomie (France) and the University of Birmingham (UK). SOHO is an international project of collaboration between ESA and NASA.

We are grateful to NRL, ESA and NASA for the collaborations in this research. We thank the NOAA-SWPC (National Oceanic and Atmospheric Administration, Space Weather Prediction Center) for the collaboration in the framework of HELCATS.
