The apparent path of the Sun across the sky. ... The path of the Sun across the celestial sphere is very close to that of the planets and the moon. ... In one year, as the Earth completes a full circuit around the Sun (drawing above), the Earth-Sun line and its continuation past Earth sweep the entire plane. ... Since the Sun and Earth are in the plane of the ecliptic, the line is automatically in that plane too; if the moon is also on the same line, it must be in the plane of the ecliptic as well. ...

Prime focus adapter . The optical reducer is mounted on the universal adapter of the prime focus, which contains two movable bundles of fibers for the off-axis guiding, lamps for the calibration of the wavelength scale (a He-Ne-Ar lamp) and for flat fielding (a continuous spectrum lamp). The lamps are placed in an integrating sphere providing uniform illumination of the field. ...

Every body is held together by two forces, its self-gravitation and its internal strength due to molecular bonding. ... A few of these cases have been obviously attributable to the tidal forces of Jupiter (Comet Brooks 2 and Comet Shoemaker-Levy 9) or the Sun (the Kreutz comet family), while other splittings have to be attributed to less obvious causes. ...

... 2001: . The distances to 50 galaxies in the vicinity of three most nearby galaxy clusters were measured. The radius of the "zero velocity sphere", isolating each group from the cosmological expansion is in the range from 0.95 to 1.25 Mpc for these groups, leads to the estimates of the total mass of groups ranging from 1.2 to 2.7 trillion solar masses. These results agree with the value of the mean matter density in the Local Universe from 0.05 to 0.10 in critical density units. ...

... This paper presents an algorithm for solving antenna based polarization leakage in a radio interferometer using co-polar observations of unpolarized sources. If ignored, polarization leakage manifests itself as closure errors in parallel hand (co-polar) visibilities. ... Hence, polarization leakage manifests as increased closure errors . ... The closure phase due to polarization mis-matches between phased antennas in a radio interferometer therefore naturally measures the Pancharatnam phase. ...
