Status: ongoing

Keywords: radio astronomy, solar physics, space weather

SUMMARY

e-Callisto consists of more than 139 radio spectrometers set up in over 75 locations reaching from Mongolia to Uruguay. The global distribution of the instruments allows for observing solar radio emissions received in different regions of the planet and without interruptions during night time. Of particular interest are the radio bursts which frequently occur after a solar flare, and may lead to radio blackouts and in the interruption of radio communication. Radio bursts are a central indicator of space weather.

The Institute for Astronomy at ETH Zurich has been operating the Bleien radio observatory since 1979. Various antennas and spectrometers have been in operation and still are today. In 2010 heliophysics moved to the Institute of 4D Technologies at Fachhochschule Nordwestschweiz (FHNW) in Windisch, Switzerland, where a new group was built up. FHNW is now responsible for archiving all solar data and manages the analysis software. Credit: craf.eu

Radio Astronomy in Switzerland

On the occasion of the 40th anniversary of the Bleien telescope in 2019, its co-founder Prof. Arnold Benz summarized the history of radio astronomy at ETHZ. In the meantime radio astronomy has continued at the Institute for Data Science FHNW with e-Callisto integrated into ESA’s Space Weather Service Network SSA, new research projects carried out such as VLA-Flares and AstroSignals and I4DS participating in the Swiss effort to join the biggest radio astronomy project of the future – the Square Kilometer Array SKA.
