In the period 12-15 July 2021, Dublin Institute of Advanced Studies /DIAS/, as a partner of the STELLAR project, with the Institute of Astronomy with National Astronomical Observatory "Rozhen" at the Bulgarian Academy of Sciences (IA with NAO-BAS) as coordinator, organized and held an online workshop on "Space Weather, Solar Activity and Data Analysis". 37 Bulgarian and foreign students, PhD students and scientists participated and had the opportunity to gain theoretical and practical knowledge in the field of space weather and learn more about solar activity. Some of the workshop topics were solar radio bursts, solar interaction with planets and interplanetary space and observations of the Sun in the radio range of the electromagnetic spectrum. The programme also included exercises on observational data processing and [...]

Forty years since the official opening of the National Astronomical Observatory – Rozhen (NAO Rozhen) will be celebrated on 13 March 2021. In its first years, NAO Rozhen is a scientific astronomical complex of three telescopes: a universal 2-meter telescope for photometric and spectral observations and two smaller telescopes: 50/70-cm Schmidt and 60-cm Cassegrain. The first observations were made on photographic plates, and a high-speed electrophotometer was mounted on the Cassegrain telescope. In the first twenty years of the observatory’s work, more than 10 000 photographs of objects from the solar system, stars and star clusters, distant galaxies and quasars, and thousands spectra of interesting stellar objects were obtained.

LOFAR station in Onsala, Sweden. The low-band antennas (10-90 MHz) are visible on the left, and the high-band antennas (110-240 MHz) - on the right. Source: ASTRON A new scientific infrastructure complex, coordinated by the Institute of Astronomy with National Astronomical Observatory (IA with NAO), will be included in the updated National Roadmap for Scientific Infrastructure 2021-2027 (NRSI). Over the last half century, our knowledge of the universe has been enriched by astronomical observations in the optical, infrared, and ultraviolet regions. But one region of the electromagnetic spectrum remains poorly studied - the low-frequency radio range, indicated the Institute of Astronomy. The LOFAR project for the first Bulgarian radio astronomy observatory, proposed by a team from the Institute of Astronomy with National Astronomical [...]
