Motion of the sun in SL

Until now I haven´t collected all the information relating to other viewers (SL officer, Singularity, Firestorm, etc) as well as the combination with of other cycles of day, but I put here all the information that I pick so far about "Alchemy", the viewer who I currently use:
 * Sunrise: It takes about six minutes, from one minute before sunrise and up to five minutes later; the texture of the sun change each 10 seconds in all the process and so continued in the next phase.
 * Morning to Midday: This process has two phases, the first phase has a duration of 25 minutes (texture of the sun still moving and changing its size every 10 seconds, until reach the zenith, at 90º high); when reach 30 minutes after sunrise, the sun jump back and relocated again to 27° altitude (the altitude data need confirmation), increase its size, and moving slowly for about an hour until reach to 90º of altitude; in the last 15 minutes to reach at noon, its size decreases considerably. From sunrise until second midday, it takes an hour and a half.
 * Midday to Sunset: for an hour the sun maintains its size in a similar manner, but 30 minutes before the sunset begins to increase in size slowly. From second midday until sunset, it takes an hour and a half.
 * Sunset: It takes five minutes to complete it, and a minute more after sunset.
