Figure 1. shows the parallactic angle rate versus azimuth angle for declinations 8 through 28 (spaced 1 degree steps from Arecibo's latitude). ...

An astronaut in low Earth orbit moves in (approximately) a big circle extending around the Earth. ... That can be interpreted as stating that in the astronaut's frame of reference, all bodies are subject to two forces, gravity and the centrifugal force, and the two are in perfect balance, adding up to zero. ... Wheel-shaped space . ... The science-fiction film "2001: A Space Odyssey" featured spinning space station, whose rotation provided the crew with "artificial gravity." ...

... If Earth's sphericity is of prime importance as the ultimate cause of weather and climate, Earth's *ROTATION* is almost as important, although the atmosphere would still exhibit motions even if it wouldn't rotate. ... Take any one of those two conditions away,and these waves become mathematically impossible. ... The Coriolis force is the force directly caused by Earth's rotation, and should be mentioned when going into a more detailed description of the physics of Rossby waves. ...

... Figure 1.1 on page 2 also illustrates the projected orientation of the WFPC2 CCDs onto the sky. ... On the CCDs this region appears as a blank "shadow" region along the X~0 and Y~0 edges of each CCD; the exact limits of this region are given in Table 2.5 for each CCD. ... The WFPC2 has two readout formats, namely full single pixel resolution ( FULL Mode), and 2x2 pixel summation ( AREA Mode which is obtained by specifying the optional parameter SUM=2x2 as described in the Proposal Instructions). ...

Phoebe . Saturn IX . Phoebe [FEE-bee] is the last of the known satellites of Saturn, at a distance of 12.952 million kilometers (8 million miles). Phoebe orbits Saturn in a retrograde direction (opposite to the direction of the other satellites' orbits) in a plane much closer to the ecliptic than to Saturn's equatorial plane. ... Scientists believe that Phoebe may be a captured asteroid with a composition unmodified since the time it was formed in the outer Solar System . ...

... the time of observation . ... Observing the Changing Position of the Sun To Establish Cardinal Directions . ... Observations of the Sun's apparent movement across the sky and its pattern of rising and setting in the east and west horizon helped to establish the cardinal directions. ... The final stage of the Sun's return was marked by the observation that the Sun had reached its highest altitude when the full width of your mitted hand could fill the gap between the Sun and the horizon. ...
