The SWELTO portal for Space Weather is now operating in real time

The portal of the SWELTO project is now operating and distributing in real-time the first “products” for future Space Weather applications. SWELTO (Space Weather Lab in Turin Observatory) aims to develop and test new diagnostic tools for analyzing space-based data providing real-time information on current conditions on the Sun and in the interplanetary space (https://www.oato.inaf.it/portfolio-items/swelto/).

During the project, new sensors will also be installed at Turin Observatory for the detection of ionospheric disturbances (with a SID monitor) and geomagnetic field disturbances (with a fluxgate magnetometer), now under calibration. Finally, through SWELTO other projects will be involved (such as PRISMA, SAMADHA, or others) that can provide through their sensors other context information related to space weather events.

Now, after more than two years of development, the SWELTO portal (http://swelto.oato.inaf.it/) is able to provide the following products in real time:

  • “SunNow”: series of movies showing the evolution of the solar corona (inner corona in the EUV, and intermediate corona in VL) as observed from space along the Sun-Earth line over the last 3 days, up to the latest data currently available from the SOHO and SDO missions;
  • “CorDens”: current distribution of the electron density in the intermediate corona as determined from coronographic images of the SOHO/LASCO instrument;
  • “WindSpeed”: current distribution of the solar wind expansion velocity measured by the coronographic image sequences acquired by the SOHO/LASCO instrument (still under test);
  • “ParkerSpiral”: current distributions of density and outflow speed of interplanetary plasma from 0.1 to 1.1 AU on the ecliptic plane as determined by a MHD numerical simulation constrained to the in situ measurements from ACE;
  • “InSitu”: evolution during the last solar rotation (about 27 days) of the conditions of the interplanetary plasma (density, speed, temperature) measured in situ at the Lagrangian point L1 by ACE.

Other modules that will provide other products in real time (such as the occurrence of solar flares or eruptions, or the distribution on the solar disk of regions potentially of interest for space weather) will be activated in the next developments of the project.

SWELTO is a “think tank” where new data analysis methods, numerical models, measurements, and ideas of interest for Space Weather are developed and tested. The project is currently fully supported by the INAF-Turin Observatory.

Call accouncement – SOLARNET Summer School for Solar Observers – A week above the clouds

Dear Colleagues,We want to draw your attention towards the *SOLARNET Summer School for Solar Observers – A week above the cloudss* which will be held at the Observatorio del Teide in August 5-9, 2019.Our purpose is to instruct students and young postdocs in the capabilities and operation of the German solar facilities at the observatory, by giving them the opportunity to 

– run real observations at GREGOR, the largest solar telescope in Europe

– calibrate data by learning how to use the existing data pipelines, Python and deep learning techniques

– learn how to complement ground-based observations with space-based observations 

– experience the observers’ life up the mountain for a weekthrough different lectures and experimental activities (programme in SOLARNET webpage available soon).  

Due to restrictions in accommodation, the number of participants is limited to 12.To register, please send an email to nbello@leibniz-kis.de with a brief statement of interest indicating your field of research and why you want to participate in the school.Registration deadline: June 15, 2019.

SOLARNET Mobility of Young and Experienced Researchers Programme Announcement (1st Call)

The SOLARNET Mobility Evaluation Committee (MEC) is pleased to announce the 1st Call for Proposals of Mobility Programme of Young and Experienced Researchers (Deadline: May 31st, 2019). 

SOLARNET (http://solarnet-project.eu/home) aims to bring together and integrate the major European research infrastructures in the field of high-resolution solar physics, in order to promote coordinated research and development. In this regard, SOLARNET will support the mobility of early stage researchers (ESRs) as well as experienced researchers as part of the networking activities foreseen in the project. This task is supervised by the MEC, which evaluates and selects the submitted applications. This first Call is related to stays to be carried on during the period September 1st, 2019  – February 29th, 2020. Detailed information about the Young and Experienced Researchers Mobility Programme can be found at http://solarnet-project.eu/Mobility-Programmes and in the attached file below:

The active sun and its effects on space and Earth climate

The large variability of the physical conditions of the Sun, on a wide range of spatial and temporal scales, represents the primary source which determines global and local changes inside the heliosphere and, what is perhaps more interesting, in the near Earth space. However, due to the extreme complexity of the system, nonlinear interactions among different parts of the Sun-Earth system play a key role, thus enormously increasing the range of physical processes involved. In fact, fluctuations in the magnetic field within the solar atmosphere act as complex modulation of plasma conditions in the interplanetary space, provoking sudden enhancements of the fluxes of solar energetic particles (SEP) and cosmic rays, as well as the UV component of the solar spectrum and the phenomenon of sudden coronal mass ejections (CME). These events are associated on Earth with the origin of magnetic storms, which have important effects on our technological society, and possibly on global changes in the climate conditions through complex interactions with the Earth’s atmosphere. The investigation of the physical processes which mainly affect solar and interplanetary space conditions, and the observation and the understanding of the processes of interaction of the solar wind with the Earth’s magnetosphere and their observations are crucial to be able to predict and mitigate those phenomena that affect space and ground infrastructures or impair the human health. For this reason, agencies and international panels include among their activities the study of Space Weather, like for instance the ESA with the Space Situational Awareness program, or contribute to a better understanding of the effect of the solar radiation on the Earth’s climate and its variations, like is done by the Inter-Governamental Panel on Climate Change. In fact an interdisciplinary approach and scientific joint ventures, involving expertise in a wide range of different fields, are urgent to face problems related to different areas of solar heliospheric and magnetospheric physics.

Our project, in fully compliance with the primary objectives of Horizon 2020, will address some of the main issues concerning the nature of the variability of solar activity, including the effects on Space Weather and Earth’s climate through the analysis of data obtained from ground-based and space observatories, through the construction of theoretical models, and through direct numerical simulations of the basic physical processes. The project will also allow to pursue the training of young researchers whose career would be developed both in the main European industries on space technologies, as well as in scientific institutions. Finally the project will support a significant part of the community involved both in space projects, such as Solar Orbiter, Solar Probe or Proba-3 and ground-based projects, such as the European Solar Telescope and the EMMA magnetometer array.
