Lord Carrington determined the solar rotation rate by watching low-latitude sunspots back in the 1850s. He defined a fixed solar coordinate system that rotates in a sidereal frame every 25.38 days. ... Carrington coordinates are heliographic and measured in latitude and longitude in that rotating frame. Carrington Time is the rotation and longitude of the point on the Sun that is at the sub-terrestrial point. ... Bartels defined his calendar based on observations of daily geomagnetic activity. ...

They are now viewed as new definitions of the sine and cosine, for the polar angle f given by x and y ( a slightly different way of formulating this definition is described further below ). ... sin 2 f + cos 2 f = 1 . ... Angle . ... Many trigonometry texts define the sine and cosine slightly differently, using the so-called unit circle . ... Then the distance AB ("the sine line") equals sin a , and the distance OA ("the cosine line") equals cos a . ...

... 3. mJy for ; . ... These criteria were chosen in order to ensure that a well defined, flux-limited sample can be achieved. ... The slightly different radio flux limits north and south of the equator are simply explained: For (and , the limit of the GB6 catalog), it is easy to see that all sources with mJy (the limit of the NORTH20CM catalog) and will be above the much lower flux limit of the GB6 catalog ( mJy; note that the converse does not hold). ...

... It?s needs solution satellite?s orientation problem for defining location of sources of ionospheric emissions above Earth?s surface with necessary accuracy. There is possibility to define orientation of photometric devices by using TV images of star background. The CCD TV camera is designed for recording of images of star sky, Earth? limb and adjoining part of Earth? surface to fix the orbit point coordinates during the measurements by FAGOT and SICH-F devices. ...

... This paper describes our application of the X Public Access ( XPA ) interface to the new version of SAOimage . XPA allows an Xt program to define named public access points through which data and commands can be exchanged with external programs. ... It provides a high-level image display programming interface as well as low-level access to gterm-image widget functions. ... When a new file name is sent to SAOtng , the appropriate header access program is run to gather the overall image dimensions. ...

... 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. ...

. The sharply-defined crater just above the center of this Cassini image shows layers of alternating bright and dark material. A thin dark layer on the crater wall appears to define the base of an ejecta blanket. Cassini was 8,314 miles (13,377 km) from Phoebe when this image was taken. NASA / JPL / CICLOPS
