Vigil/PMI: a new perspective at our Sun

Development of various analysis tools, processing pipelines, and data enhancement procedures for ESA's upcoming space weather mission

Vigil is an upcoming deep space mission from the European Space Agency. It will provide uninterrupted observations of the Sun from the L5 Lagrange point, offering a new perspective that allows us to preview space weather events as they emerge from the Sun and approach Earth. The Photospheric Magnetic field Imager, PMI, is developed at MPS to provide maps of the solar magnetic field with high reliability, continuous availability and low latency.

PMI will provide primary data products which will be calibrated and processed on-board. These data will serve as starting point for space weather monitoring, modelling and forecasting. Additionally, PMI will produce secondary data products for scientific applications, ranging from studies of the long-term behaviour of solar magnetism, to exploring the Sun’s invisible interior with helioseismic methods.

To fully exploit the opportunities presented by these observations, elaborate models are needed to create a physical context from the data, that potentially would answer long-standing open questions in heliospheric physics. Incorporating the baseline data products into these physical models requires the refinement of the inputs, which in turn necessitates an in-depth understanding of the instrument’s characteristics.

Following your interests, you could become involved in the development of various analysis tools, processing pipelines, and data enhancement procedures.

For example, the obtained magnetograms must be translated into unambiguous field vectors, synoptic charts, and coronal magnetic field line extrapolations. As an integral part of the mission development team, you will work collaboratively to ensure the project’s success and enhance its scientific return.

ESA is preparing for a mission to monitor the Sun. A world first, this upcoming space weather mission will ensure we are able to monitor, 'nowcast' and forecast potentially dangerous solar events, giving us time to protect at risk infrastructure on Earth, or life in space. For years, it has been known as the Lagrange mission, but now we have a new name: ESA Vigil.
The Photospheric Magnetic field Imager (PMI) is a compact and lightweight vector magnetograph tailored for the use on deep space missions. It strongly builds on the expertise gained in developing  the Solar Orbiter PHI instrument. PMI has been proposed and adopted as one of the key instruments for ESA’s Vigil mission. more
Department Sun and Heliosphere
The focus of this department is the solar interior, the solar atmosphere, the solar magnetic field, the heliosphere, and the interplanetary medium, as well as solar radiation and solar energetic particles. The balloon-mission Sunrise, a balloon-borne solar observatory, is managed by this department. The mission investigates our central star from a height of about 35 km. In addition to several other participations in space missions, the department significantly contributes to the ESA's Solar Orbiter. more
