2. The Angle of the Sun's Rays
... In the US and in other mid-latitude countries north of the equator (e.g those of Europe), the sun's daily trip (as it appears to us) is an arc across the southern sky. ... Moss avoids direct sunlight, and with the sun's path curving across the southern sky, the north side of a tree-trunk is the one most shaded. ...

4. High Resolution HST Images of Pluto and Charon (ESO Press Release 09/94)
... The remote planet Pluto and its moon Charon orbit the Sun at a mean distance of almost 6,000 million kilometres, or nearly fourty times farther out than the Earth. During a recent investigation by an international group of astronomers [1], the best picture ever of Pluto and Charon [2] was secured with the European Space Agency's Faint Object Camera at the Hubble Space Telescope (HST). ... The new HST image was taken when Charon was near its maximum elongation from Pluto (0.9 arcseconds). ...

17. A Catalogue of Radio Sources (1979)
... R astro-ph/0312163 5 for 170 sources (114 flat-spectrum and 56 steep-spectrum) and upper limits have been set for additional 27 sources (12 flat-spectrum and 15 steep-spectrum). The median polarization degree at 18.5 GHz for the flat-spectrum sub-sample is \Pi_{18.5}\simeq 2.7%, about a factor of 2 higher than at 1.4 GHz (\Pi_{1.4}\simeq 1.4%, based on NVSS data). For flat-spectrum sources we find a weak correlation between \Pi_{18.5} and the high frequency (5--18.5 GHz) spectral index. ...

Medium Deep Survey Information The question of the legacy left by E-ALFA is one that we need to think very carefully about. ... We present here some possible parameters for such a survey. Survey Science Objectives and Benefits: · HI mass function over a range of environments: A deep survey will be much more effective at probing the HI mass function over a range of environments (if the regions surveyed are well chosen) because it will probe more independent volumes than a shallower survey. ...
