SOLARNET

SOLARNET - High-Resolution Solar Physics Network

SOLARNET is a European networking activity to develop and coordinate the use of infrastructure devoted to high-resolution solar physics. Within this project the following topics will be addressed:

  • Existing and future facilities will be efficiently used by a coordinated Trans-national Access and Service Program.
  • Collaborations between solar research groups are fostered, and innovative partnerships to industry are reinforced.
  • The foundation to an efficient Virtual Solar Observatory, containing high quality data of world-leading solar observatories, will be laid.
  • Advanced instrumentation for existing and future solar telescopes will be developed.

SOLARNET involves all pertinent European research institutions, infrastructures, and data repositories. The project achievements will be of principal importance in defining the exploitation of the future 4-meter European Solar Telescope (EST).

 

Projects within SOLARNET with MPS leadership:

  • Fast Solar Polarimeter FSP (A. Feller)

  The goal of this activity is the development of a novel fast solar imaging polarimeter with emphasis on an increased polarimetric accuracy and high spatial resolution. The high frame rate (several 100 frames per second) of the newly developed detector allows to "freeze" the disturbances caused by turbulences in the Earth's atmosphere. This is the prerequisite to measure solar magnetic fields with unprecedented accuracy on small spatial scales.

First 2D measurement of a sunspot with a low-resolution test setup at the SST (summer 2012).

  With current solar instrumentation it is impossible to measure the spectra of all pixels over a two-dimensional field of view simultaneously. The new type of spectrograph developed within this project will overcome this limitation by replacing the spectrograph slit by a rotated microlens array. The microlenses act like the pixels of a detector, but instead of only counting the number of photons, the attached spectrograph allows to obtain full spectral information of the incoming light. This is essential to understand fast processes in the solar atmosphere, like reconnections, jets, or wave propagation.

  • German Science Center for the Solar Dynamics Observatory (L .Gizon)

  The German Science Center for the Solar Dynamics Observatory (GSC-SDO), hosted at the MPS, offers access to the data obtained with the Helioseismic and Magnetic Imager (HMI) on board SDO. Every 45 seconds five standard data products of the Sun with 16 million pixels each are generated. Standard SDO/HMI data products are made available to the solar physics community through a distributed data record management system.
