Since its discovery the Cosmic Microwave Radiation (CMB) has been one of the pillars of modern Cosmology. ... Further development of this work is the application of already tested algorithms to disentangle the foreground emission from the CMB maps and the determination of the CMB intrinsic emission. ...

Observation Strategies . For broad band filters the sky background will limit the detection of faint targets. ... See Table 6.3 on page 113 for sky level as function of ecliptic coordinates.) If these higher sky levels would severely impact the science data, observers should consider specifying the special requirement LOW-SKY on the Phase II proposal. ... Scattering of bright Earth light in the OTA can produce non-uniformities in the background which may hamper analysis of faint target images. ...

... The J, H and K bands are characterized by a bright background, such a background is mainly due to the emission of atmospheric lines and of thermal radiation. ... If the source cover a large fraction of the slit, spectra off-source must be observed to adequately sample the sky background. ... The on chip integration time (time spent in each position of the slit) must not exceed 40 seconds in J and H bands and 60 seconds in K band. ... We suggest a sequence of 10 for each elementary integration time. ...

In 2007-2008, the planet Uranus will reach one of its annual equinoxes for the first time since 1966. As a consequence, its five major satellites orbiting in the equatorial plane will undergo a season of mutual eclipses and occultations very similar to the one that Jupiter's Galilean satellites undergo every 6 years. ... Some of these events occur when Uranus is at conjunction, or the satellite is transiting or too close to the limb of the planet. ... Complete table of events . ...

... 88, Jan. 1983, p. 1-15. l. A survey of extragalactic radio sources made using driven declination scans is reported covering an area of about 0.07 sr to a limiting flux density of 35 mJy. The fast-scan survey was carried out at a galactic latitude greater than 17 deg with the NRAO 91-m telescope operating at 4.755 GHz, and the 480 sources detected were reobserved at 1.4 GHz with the National Astronomy and Ionosphere Center 305-m telescope at Arecibo. ...
