1. The International Space Station becomes the second brightest object in the
... Armagh Observatory, 24th March 2009: The International Space Station ( ISS ) has recently become the second brightest object in the night sky тАФ even brighter than the planet Venus, and second only to the Moon. Evenings will provide the chance of a spectacular view, if the sky is clear, as for the next few days the orbit of the ISS around the Earth repeatedly takes it over Ireland. ... At its best, it is now the second brightest object in the night sky. ...

... The time taken to read through a quadrant on the array sets a fundamental limit on the fastest electron collection rate which can be achieved by resetting all the pixels. An inherent consequence of the methods of operating the NICMOS array detectors in the ACCUM, MULTIACCUM, and RAMP modes is therefore that there is a minimum possible exposure time, ~ 0.6 seconds (0.302 for MULTIACCUM), set by the time required to read the array. ... Figure 15.1 illustrates the operation of bright object mode. ...

12. More on Kepler's Second Law
... Kepler's Laws . ... Second Law . 12a. More on 2nd Law . ... Kepler's 2nd law prescribes the way the velocity V of an object orbiting a single center varies around its orbit: . The rate at which the line to the center ("radius vector") covers area does not change around the orbit." As noted in section #12 , this means that the object's velocity V increases when its distance r decreases, and vice versa. ... Because by Kepler's 2nd law, the Earth moves in its orbit a little faster in winter. ...
