Birmingham Solar Oscillations Network
From Wikipedia, the free encyclopedia
The Birmingham Solar Oscillations Network (BiSON) consists of a network of six remote solar observatories monitoring low-degree solar oscillation modes. It is operated by the High Resolution Optical Spectroscopy group of the School of Physics and Astronomy at the University of Birmingham, UK, in collaboration with Sheffield Hallam University, UK. They are funded by the Science and Technology Facilities Council (STFC).
BiSON operates automated resonant scattering spectrometers in astronomical domes or mirror fed systems. The current sites are:
- Mount Wilson Observatory, California, USA
- Las Campanas Observatory, Region IV, Chile
- Observatorio del Teide, Tenerife, Canary Islands, Spain
- South African Astronomical Observatory, Sutherland, South Africa
- OTC Earth Station Carnarvon, Carnarvon, WA, Australia
- Paul Wild Observatory, Narrabri, NSW, Australia
The BiSON has been collecting data continuously on solar oscillations since 1976, making it the longest running helioseismology network with data covering three solar cycles.
