Hi,
Yes, your graph looks fine now. The sky seems to be clearer than when I was there in March.
Beware that the sun is not a good timekeeper, solar "noon" can vary by as much as +/- 20 minutes during the year! If you want to know why, then google "The Equation Of Time".
An easy way to determine the exact time of noon is that it's half-way between sunrise and sunset, as quoted in Cumulus. It's very easy for me because I'm almost exactly on the Greenwich meridian and currently noon is showing as +4 minutes, i.e. 1.04 pm because we're on "British Summer Time" (or Daylight Saving Time). So your 1.08 pm seems exactly correct if you're 16 degrees * 4 minutes = 1 hour 4 minutes ahead of the sun.
Cheers, Alan.
