Network of six solar helioseismology observatories
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).
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.
Remote observatories.
BiSON operates automated resonant scattering spectrometers in astronomical domes or mirror fed systems. The network was established in 1976 with two permanent stations; the addition of several more sites culminated with the addition of a sixth in 1992. The current sites are:
