Steve,
I guess the basic answer must be 15 degrees per hour - which will
be constant throughout the day (and night). I sure hope you'll charge the
solicitor whatever he would charge you!


That won't be the rate at which the altitude (elevation) angles decreases
with time. You are referring to the compass direction of the sun. The
elevation change would be fastest around 18z and then decrease as the
evening progresses. The path of the sun is easiest seen as a sine curve.
