The Swiss Society for Astrophysics and Astronomy (SSAA) officially announced the attribution of the Edith Alice Müller Award 2020 during its assembly that was held online on 9 October 2020. The awards have been attributed to Dr Gioele Janett (IRSOL) and Dr Ewelina Orbzud (UNIGE) for their PhD thesis .
Janett successfully completed his PhD at IRSOL in 2019 with a thesis on
Numerical Methods for the Transfer Equation of Polarized Radiation
under the guidance of Prof. Siddhartha Mishra and Dr. Oskar Steiner.
IRSOL greatly congratulates the awardees.
The first WHPI “Show and Tell” days occurred on 14th-15th September, 2020. The agenda can be found here. During these two days, video tutorials followed by a Q&A about the observational data obtained during the 4th perihelion of Parker Solar Probe by ground- and space-based solar observatories were shown. IRSOL supported this campaign and contributed with unique and complementary ground-based observations, see here.
The video tutorials included information about the scientific value of the data, how the measurements were performed, the data reduction and also how the data can be accessed. The presentations are archived and can be found here.

During the 4th perihelion (the point closest to the Sun in an orbit) of Parker Solar Probe, a synergy of ground-based observatories around the world supported the spacecraft’s in-situ measurements by remote sensing.
This was made possible thanks to the lined up constellation between Earth, Parker Solar Probe and the Sun. The joined effort is embedded in the Whole Heliosphere and Planetary Interactions initiative. This is expected to draw a unique coherent picture of the complex energetic and magnetic structures reaching from the solar surface to the outer layers of the solar atmosphere.
The NASA coordinated mission Parker Solar Probe, a mission “to touch the Sun”, was launched in August 2018 to provide new insights on solar activity and how to improve space-weather forecasts. Since then, Parker Solar Probe is constantly monitoring it’s direct environment while getting closer and closer to Sun. During the 4th perihelion, Parker Solar Probe reached the outer part of the corona, filled with plasma and magnetic fields.
IRSOL joined the synergy by taking high-precision spectro-polarimetric data of the magnetic foot-points on the Sun. The measurements at IRSOL provide critical complementary information on the magnetic activity located in about 800 km height above the solar surface.
