... Bad Astronomy . ... I think I will break from my usual format of Bad Astronomy/ Good Astronomy by saying that the way we define seasons currently is not strictly bad, but I feel (in my opinion!) that it could be better. The definition of when the seasons begin is at the moment of solstice or equinox; that is, winter (in the north) starts on December 22 nd and summer starts on June 22 nd . ... Now imagine breaking up the Sun's 46 degree up-and-down yearly swing into 1 day intervals. ...

Changes in the WFPC2 observation scheduling system were introduced early in 1999 primarily in order to increase the scheduling efficiency of HST observations starting with Cycle 8. First, the South Atlantic Anomaly (SAA) contours used to limit WFPC2 observations have been modified slightly. ... This change results in a 3% increase in designated SAA-free orbits, which allows better scheduling efficiency, and is expected to impact negatively less than 0.1% of WFPC2 science observations. ...

... Each ferrule will be used to plug approximately 300 holes. We must be sure the ferrules will not wear excessively during use; 1 mil reduction in diameter of a ferrule is enough to reduce light throughput by approximately 1%. ... Stainless steel ferrules offer lower precision (which will lose us approximately 1/2 to 1% light compared to ceramic), but they are relatively inexpensive, readily available with the hole diameter we require, and immune to cracking. ... Hence the wear was not very deep. ...

... It turns out one possibility is a form of matter/energy invented by Einstein in the 1920s to make sure his equations of General Relativity did not predict the Expansion of the Universe. Although Einstein was willing to predict several things with his equations of General Relativity, he obviously thought an expanding Universe was too much, and so he invented the Cosmological Constant, which repels itself, and was meant to balance the force of gravity, and make the Universe static. ...

spaceweb@oulu.fi - last update: 20 November 1998, 1440 UT (RR) . The 'space weather' have been coined to point out that many of the phenomena studied in space physics have also important practical consequences (e.g., Davenport, 1996). In addition to the geomagnetic activity , also changes in the atmosphere , or even comets and man-made debris in space, can be of importance. ... The other serious consequence of bad space weather is the possibility of damage to Earth orbiting satellites. ...
