Did you ever want to know exactly WHEN the sun would set right between the golden gate from Indian Rock? Pt. Isabel? Mt. Diablo? I sure did...and spent a few hours on this one... man I'm cool.

UPDATE: Found another resource...at the US Naval Observatory. Go to... http://aa.usno.navy.mil/
then "Data Services" then "Rise/Set/Transit Times for Major Solar System Objects and Bright Stars". NOW I can calculate the Moon!!!
Use http://www.usno.navy.mil/USNO/astronomical-applications/data-services
Look for readings between 240 and 277 for Berkeley and SF...

OK, so you'll have to click on this and enlarge it...
1) Open your National Geographic Topo program. Using the Compass Tool, click on the location you want to be,
then click on the bridge...this will get you the Solar Azimuth angle (make sure it's True North).
SA from:
Pt. Isabel: 235.44
Indian Rock 245.42
ENVIRON 260.74
Mt. Diablo 262.02
...what is an azimuth angle? http://solardat.uoregon.edu/A.html#azimuthangle

2) Go to the link below, and fill in the blank.
You'll need to put in the lat, long, and if you choose "Plot dates 30..." you'll see something like this.
For Berkeley long = -122.19, lat = 37.54
Now this gives you an approximation:
and coveres the entire spectrum
240 to 300 Solar Azimuth Angles...
Pt. Isabel: never happens...
Indian Rock: Jan 21
Environ: Feb 24, 25?
Mt. Diablo: Feb 20?

3) Now the sunset happens when the solar zenith angle is 0.
