Welcome to our new postgraduate students!

Publication date:

A warm welcome to our new postgraduate students Magnus Woods and Alexander James! 

Alex joins us from the University of Southampton and will be working with Prof. Lucie Green and Dr. Gherardo Valori on a Leverhulme Trust funded project which bridges the gap between theory and observations of solar activity. In particular he will focus on the study of the magnetic field of active regions that produce coronal mass ejections - starting with the vector magnetic field measured in the photosphere which can be used to understand the evolution of the magnetic field configuration and stored magnetic energy in the atmosphere.

Solar Orbiter heat shield attached

Publication date:


The Solar Orbiter mission passed a major milestone on Friday 13th March when the heat shield was attached to the engineering model. Solar Orbiter is the next major space mission for studying the Sun, and is due to launch in 2018. Using a highly elliptical orbit, the Solar Orbiter spacecraft will get to within 0.3 AU away from the Sun and as such it requires a heat shield to protect the delicate electronics and instruments from the full effects of the extreme environment it will face there. MSSL has a significant involvement in the Solar Orbiter mission on both the remote sensing and in-situ sides. On the remote sensing side, the electronics box for the Extreme Ultraviolet Imager (EUI) is being built at MSSL, while on the in-situ side, MSSL is the Principle Investigator institute for the Solar Wind Analyser suite of instruments. The photo attached shows the heat shield on the left and on the right, Prof. Louise Harra (EUI Co-PI) and Prof. Chris Owen (SWA PI) at Astrium in Stevenage to see the Solar Orbiter heat shield being attached.

EUI Working group meeting at MSSL

Publication date:


From 3-5 March, the Solar Group at MSSL played host to the 15th Consortium meeting for the Extreme Ultraviolet Imager (EUI), one of the instruments onboard the forthcoming Solar Orbiter mission. With the development and construction of the EUI instrument continuing at MSSL as well as at partner institutions across Europe, this meeting was an opportunity to consider the planned observing campaigns and ensure the success of the mission. The MSSL group were joined by scientists and engineers from the Max Planck Institute for Solar System Research, Institut d'Astrophysique Spatiale, the Royal Observatory of Belgium, Centre Spatial de Liège, PMOD and Institut d'Optique.

Louise Harra at DKIST site

Publication date:


Professor Louise Harra, Head of the Solar Physics Group at MSSL is currently visiting the site of the Daniel K. Inouye Solar Telescope (DKIST), which is situated on the mountain of Haleakala on Maui in Hawaii. As can be seen from the photo above, construction is continuing, with the project on track for first light in 2019. When completed, DKIST will be the largest solar telescope in the world, with a primary mirror of just over 4m. This will allow scientists to study the surface of the Sun in unprecedented detail, providing a unique insight into how magnetic fields are generated and how they evolve with time. MSSL is part of a UK consortium providing cameras for the different instruments on DKIST. For more information on the role that MSSL are playing as part of the DKIST consortium, please see the UCL MAPS webpage here.
