Arlot Institut de m'ecanique c'eleste et de calcul des 'eph'em'erides, Paris, France The Institut de m'ecanique c'eleste et de calcul des 'eph'em'erides (IMCCE), formerly known as Bureau des longitudes, produces, since its creation (1795), the French ephemerides for most of the bodies of the solar system. ... The code of several theoretical models is provided...

... Under certain conditions, like those in the nucleus of a QSO, all atoms can be made to emit light at particular wavelengths. ... If that source is approaching the observer, the wave is squashed up onto itself making the wavelength shorter. ... This is redshift. ... You can see how the section of the QSO spectrum which we observe changes with redshift. ... We then see how far we had to slide the observed spectrum along the scale to make it match and that is the objects redshift. ... The 2QZ team . ...

VISTA is a 4-m class wide field survey telescope for the southern hemisphere, equipped with a near infrared camera (1.65 degree diameter field of view at VISTA's nominal pixel size) containing 67 million pixels of mean size 0.34 arcsec and available broad band filters at Z,Y,J,H,K s and a narrow band filter at 1.18 micron. A wide field visible camera, if constructed, could also be used on VISTA. ... Tile . ... ESO VISTA Public Surveys . ...

GEOMAGNETIC SUDDEN COMMENCEMENTS (from SGD Explanation of Data Reports) Sudden Commencements and Solar Flare Effects - These reports are provided by Observatorio del Ebro, Roquetes, Spain, on behalf of the IAGA Service on Rapid Magnetic Variations. ... From then until 1970 they were published quarterly in Solar-Geophysical Data (SGD). Beginning with December 1970 these data are published monthly and, thus, are based on fewer reports and differ slightly from similar data published previously. ...
