The European Commission approved the establishment of LOFAR ERIC (European Research Infrastructure Consortium), in which Bulgaria is a full founding member. The main task of LOFAR ERIC is to provide the European astronomical community with a coordinated exploitation of LOFAR (Low Frequency Array), the world's largest radio telescope at low frequencies below 250 MHz. The LOFAR ERIC aims to position LOFAR as a world-leading research infrastructure that will, in the long term, maintain global leadership positions in radio astronomy. LOFAR is an extremely versatile modern radio telescope that can be used to observe the most ancient stars and galaxies as well as our Sun and the dynamics of the Earth's ionosphere. In essence, it is a pan-European infrastructure for low-frequency radio astronomy observations with antenna [...]

  collage drawing showing high-energy ions from the Sun interacting with the Earth's magnetosphere and attacking the electronics of satellites in orbit around the Earth "A review of Solar Energetic Particles prediction models" - under this title, a publication appeared on ScienceDirect, Elsevier's leading platform for peer-reviewed scientific literature. The international team of authors in the study includes scientists from the Institute of Astronomy with NAO - BAS: Assoc. Prof. Kamen Kozarev, Assoc. Prof. Rositsa Miteva, Sen. Asst. Prof. Momchil Dechev and the PhD student from Egypt Mohamed Nedal. Solar Energetic Particles (SEPs) are streams of protons, electrons, and ions accelerated to high energies in the huge eruptions on the Sun's surface and which spread throughout the solar system, "surfing" on the interplanetary [...]
