Does the tropical sun rise in the east?

...and sink in the west?

Well not exactly, at least here in Bangkok in the hot season, April of every year. The illustration here which I made in the pub the other night shows this for June 21, summer solstice. It actually rises in the northeast and sets in the northwest, and that is a very important detail because it affects which condos get deadly solar heat at different times of the day.


Worth a book in itself? Maybe. It would have saved me a lot of discomfort, and money too, if I had understood this fifteen years ago.
