GALLEX

The GALLEX experiment was performed by an international collaboration headed by MPIK Heidelberg. GALLEX measured the solar neutrino flux produced inside the Sun by proton-proton fusion. As target for neutrino capture, a large amount (30 tons) of the rare element Gallium in form of an aqueous solution of Galliumtrichloride was used. To protect the detector from the interfering cosmic radiation one must go deep underground. Hence the experiment was carried out under the shielding of Italy's highest mountain outside the Alps, the Gran Sasso d'Italia in the Abruzzo region.

Midcourse Space Experiment (MSX)

The MSX observatory is a Ballistic Missile Defense Organization project which offers major benefits for both the defense and civilian sectors. It was launched on a Delta II vehicle on April 24, 1996, into a 900 km, polar, near-Sun synchronous orbit. The spacecraft featured an advanced multispectral image capability to gather data on test targets and space background phenomena.
The infrared sensors operated at 11 to 12 degrees Kelvin by employing a solid hydrogen cryostat. The IR instruments span the range 4.2 - 26 microns. The focal plane array consists of five bands and the radiometer beam-size is more than 25 times smaller than IRAS. As a result, much greater spatial resolution than anything currently available has been obtained. The cryogen phase of the mission ended on 26 February 1997. During the ten month cryogen phase of the mission over 200 Giga Bytes of data on Celestial Backgrounds were obtained.
See the MSX Celestial Backgrounds Team Home Page for additional details.

THEMIS - Heliographic Telescope for the Study of the Magnetism and Instabilities on the Sun (THEMIS)

THEMIS (Télescope Héliographique pour l'Etude du Magnétisme et des Instabilités Solaires) is a new generation Franco-Italian solar telescope built by INSU/CNRS (France) and CNR (Italy). The main scientific goal for which it has been designed is the accurate determination of the vector magnetic field.

The European Incoherent SCATter Scientific Association (EISCAT)

The EISCAT Scientific Association is an international research organisation operating three incoherent scatter radar systems, at UHF (931 MHz), VHF (224 MHz) and 500 MHz, in Northern Scandinavia. It is funded and operated by the research councils of Norway, Sweden, Finland, Japan, France, the United Kingdom and Germany.

Transition Region And Coronal Explorer (TRACE)

TRACE will enable solar physicists to study the connections between fine-scale magnetic fields and the associated plasma structures on the Sun in a quantitative way by observing the photosphere, transition region, and corona.

Views Of The Solar System

Views Of The Solar System has been created as an educational tour of the solar system. It contains images and information about the Sun, planets, moons, asteroids, comets and meteoroids found within the solar system. The image processing for many of the images was done by Calvin J. Hamilton.

INACTIVE LINK ? - 341 --- Wilcox Solar Observatory (WSO)

The Wilcox Solar Observatory began daily observations of the Sun's global magnetic field in May 1975, with the goal of understanding changes in the Sun and how those changes affect the Earth; this is now called space weather. Now low-resolution maps are also made of the Sun's magnetic field each day, as are observations of solar surface motions. The observatory is located in the foothills just west of the Stanford University campus.

Zurich Solar Radio Spectrometer

The Radio Astronomy Group (RAG) of ETH in Zurich, Switzerland, recorded solar radio spectrograms with an analog spectrometer called Daedalus (1974-1993) in the range of 100-1000 MHz. Its observation list can be accessed directly. Two digital spectrometers, Ikarus (1978--1985) and PHOENIX (1988--1994), cover a range from 100--1000 MHz and 0.1--3 GHz, respectively. And since 1998 the new and improved Phoenix-2 Spectrometer covers a range from 0.1 -4 GHz. These data can be accessed by the ASPECTimage retrieval system. Their observation list contains references to frequency programs that indicate which frequencies were observed. More information can be obtained from RAG members.
