Azimuth of Sri Pada

To compute Azimuth of Sun at Sunrise and direction to Sri Pada

  1. Go to URL
  2. Locate your latitude longitude by finding the building of observation by paning and zooming on that Google Earth interface.
  3. Copy and Paste below the latitude and longitude in degrees to compute the Azimuth to SriPada the coordinates of which have already been entered.
  4. On the Google Earth Interface the computation defaults to current day and time. Enter time Zone as +5.5 and save. Time of sunrise and Sunset are also given.
    The Sunrise behind Sripada event is from 7 to 10 min after time of sunrise since the tip of Sripada 2.2 km high is 2 degree above the horizon from Colombo 70 km away.
  5. Enter a time 8 min after sunrise when the top of Sun is at the level of top of the peak. Compute Azimuth of Sun.
  6. Change date till you have Azimuth match to within +/- 0.25 degrees of Azimuth to Sri Pada
Around March close to spring equinox on March 21st the Azimuth changes about 0.4 degrees north each day. So you may get one day or two you will see the peak silluated on the surface of Sun at Sunrise. Each year azimuth changes by 0.1 degree and after 4 years and a leap day returns to same azimuth on same day of year from same location.

From Google Earth interface locate you place of observation and enter
