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. ...

... 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. ...
