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.
