Radio Telescopes
- Nançay Radioheliographe is an interferometer composed of 48 antennas observing at meter-decimeter wavelengths. The radioheliographe is installed at the Nançay Radio Observatory (France).
- Owens Valley Solar Array is a radio interferometer operated by New Jersey Institute of Technology consisting of 7 antenas observing from 1 to 18 GHz in both left and right circular polarization. OVSA is located in Owens Valley, California, (USA), now is under reform, increasing to 15 the total number of antennas and upgrading its control system.
- Nobeyama Radioheliograph is an interferometer installed at the Nobeyama Radio Observatory (Japan) formed by 84 small (80 cm) antennas, with receivers at 17 GHz (left and right polarization) and 34 GHz operating simultaneously. It observes continuously the Sun, producing daily snapshots. (See link)
- Nobeyama Radio Polarimeters are a set of radio telescopes installed at the Nobeyama Radio Observatory that observes continuously the full Sun (no images) at the frequencies of 1, 2, 3.75, 9.4, 17, 35, and 80 GHz, at left and right circular polarization.
- Solar Submillimeter Telescope is a single dish telescope, that observes continuously the Sun at 212 and 405 GHz. It is installed at Complejo Astronomico El Leoncito in Argentina. It has a focal array composed by 4 beams at 212 GHz and 2 at 405 GHz, therefore it can locate instantaneously the position of the emitting source. SST is the only solar submillimeter telescope currently in operation.

Famous quotes containing the word radio:
“Now they can do the radio in so many languages that nobody any longer dreams of a single language, and there should not any longer be dreams of conquest because the globe is all one, anybody can hear everything and everybody can hear the same thing, so what is the use of conquering.”
—Gertrude Stein (1874–1946)
