External influences on spin parameters for INTERBALL - AP . ... The main interest is that almost all kind of external influences to parameters of motion (eclipse, normalization, ROS) are presented in the one time interval. Three upper panels illustrate the spin velocity, the angle between kinetic moment and sun direction, and the nutation.All external events are represented on the lowest panel as blue, green and yellow columns. ...

... 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. ...

In July, 1976, Viking Orbiter 1 was acquiring images of the Cydonia region of Mars as part of the search for potential landing sites for Viking Lander 2. ... Using the height field, it is also possible to view the "Face" from different look directions, by mapping the Viking Orbiter image directly on the the topography and then placing the "viewer" at different locations. ...

... PTSLEW is the time allowed in a pointing sequence to get to source before beginning the raster. ... In actual use, if a scan start time is specified, the interval between that start time and the previous stop time is added to the PTSLEW to set the duration of the slewing scan. For most pointing observations, it is probably best to set PTSLEW to something small, perhaps the same as PTDUR , and use dwell time scheduling. ... Default: 160 , a sensible choice. Usage: Defaults to previous scan. ...

... Galaxy formation and evolution is one of the key problems of modern astronomy. Galaxies in the universe come in a large variety of shapes and sizes, which we refer to as the Hubble sequence. The study of galaxy formation and evolution aims at explaining this variety as well as its statistical properties. Though the formation, and to some extent the evolution of galaxies still is one of the most active research areas in astrophysics. ...

Prague, August 16, 2006 . To start a new GCVS edition (presumably an electronic one), combining the stars of the GCVS IV and Name Lists (and maybe eventually merged with automatic-survey variables), we need to revise the GCVS classification system. ... Our approach: the classification scheme must be simplified, more detailed classification should be given in specialized catalogs for particular types, but the GCVS classification should take into account new astrophysics. ...
