If my latitiude is 40 degrees south and the sun is at 15 degrees north declination, it will rise in the ____ (direction), transit _____ degrees _____ of the zenith, and set in the ______ (direction).
Use the sunrise equation to find the direction of sunrise:
cos(dir. of sunrise) = -tan(latitude of observer)xtan(declination of sun)
I come up with 77 degrees, or NNE, roughly.
Using the positive value, instead of the negative, I get 103 degrees for the direction of sunset.
In terms of the horizon, this transit measures 26 degrees, south of zenith.
