The consortium of the European Solar Telescope (EST) met last week in Prague to discuss the roadmap towards the future implementation of EST and assess the progress of the EST-related projects. The meetings, held over three days at the Czech Academy of Sciences, brought together a significant representation of the European Solar Physics community in the field of high spatial resolution.

Members of the PRE-EST project shared the latest strategic and technical developments related to EST. This project, funded by the EU H2020 programme to develop a detailed plan for the implementation of EST, has worked intensively during the last year to consolidate the EST design, including the adoption of an 800-mm adaptive secondary mirror to ensure that EST is equipped with the most advanced technology. All works have a clear aim in sight: having a detailed Construction Plan by 2022.

SOLARNET H2020 also held its first annual meeting in Prague. The EU-funded project, which continues the work started by its predecessor under the same name, aspires to integrate the major European infrastructures in the field of high-resolution solar physics. During this first meeting, a comprehensive review of the annual activities was made: networking activities and schools, mobility programmes to ensure access to research infrastructures, and joint research activities.

The meetings were supported by the Czech Republic Ministry of Youth, Education and Sport under the large research infrastructure project LM2018095. The commitment of the Czech Republic with EST was recently reaffirmed in the last update of the Czech National Infrastructure Roadmap, which prioritised and consolidated the Czech participation in the construction and operation of the European Solar Telescope.


EAST General Assembly

The European Association for Solar Telescopes also held its annual meeting. Among other aspects, Dr. Salvo Gugliemino (Università di Catania, Italy) was elected as the new EAST Executive Director (in substitution of Dr. Marco Stangalini).

Founded in 2006, the association is now formed by 26 institutions from 18 countries (Austria, Belgium, Croatia, Czech Republic, France, Germany, Greece, Hungary, Italy, Norway, Poland, Portugal, Slovakia, Spain, Sweden, Switzerland, The Netherlands and UK). The goal of the association is to ensure access of European solar astronomers to world class ground-based high-resolution observing facilities.  EAST is also the promoter of the European Solar Telescope.



The European Solar Telescope participates in the 2nd ESO – Swiss Industry Information Day

The European Solar Telescope was among the international projects invited to the  2nd ESO – Swiss Industry Information Day. During his talk, EST System Engineer Miguel Núñez described the technology needs of the project for the next years (tendering activity, procurement batches...), detailing the high-tech demands of the EST instrumentation. He was accompanied by Juan Cózar, EST Chief Mechanical Engineer, and Michele Bianda, Swiss Coordinator of EST. 

The 2nd ESO – Swiss Industry Information Day took place on the 15th of November in the city of Olten. Organised by the Laboratory of Astrophysics of the École Polytechnique Fédérale de Lausanne and the Industry Liaison Office, the meeting was mainly focused on the current contract status and technology roadmap of the ESO, and included keynote speakers from the ESO Organisation in Munich. The meeting also included information on the procurement status of international projects like the Square Kilometre Array (SKA), the Cherenkov Telescope Array (CTA), and the European Solar Telescope (EST).

SUCOSIP starts the evaluation process of a possible location for EST at ORM

Published: Monday, 18 November 2019

A proposal for the preferred location of the European Solar Telescope was presented to the International Scientific Committee of the Observatorios de Canarias.

The EST project presented a proposal to the International Scientific Committee of the Observatorios de Canarias (CCI) to consider a location near the Swedish Solar Telescope (SST) at the Observatorio del Roque de Los Muchachos (ORM, La Palma) as a preferential site for the telescope, following the decision adopted by the EST project Board on October 4th. The proposal was presented to the SUCOSIP (SUb-COmmittee on SIte Properties of the International Scientific Committee) during its meeting in La Laguna on November 13th, 2019. SUCOSIP is a committee of experts which, among other tasks, supervises the impact that proposed new infrastructures may have on existing facilities and recommends actions that could minimise this impact.

SUCOSIP acknowledged the excellence of the proposed site for solar observations, as has been demonstrated by the outstanding performance of the SST. The group recommended that the EST project perform further analyses to study the influence of the EST building and associated facilities on the nearby William Herschel Telescope, taking into account the particular wind profiles at the observatory. The impact on other minor surrounding facilities should also be analysed. SUCOSIP concluded that it is most important to carry out parallel solar site testing measurements at the SST and the Vacuum Tower Telescope (VTT), located at Teide Observatory (OT, Tenerife) using the Wide-Field Wavefront Sensor installed by the Stockholm University at these two telescopes. The outcome of such parallel measurements will be most interesting for the diurnal characterisation of both observatories.

SUCOSIP presented these recommendations to the CCI during its 82nd meeting, held in the University of La Laguna on November 14th, 2019. The CCI agreed with the recommended actions. The process of evaluation will require further iterations in SUCOSIP's future meetings before a final decision by the CCI can be taken.
