Description:
  • This analemmatic sundial is in a circular plaza about 20 feet (6m) in diameter. The dial has Arabic numbers 6am to 6pm, centered on 12 noon with no longitude correction (only about 7 minutes of time). The zodiac walkway is unusual in that it reverses the left-right position of June and July, simulating the analemma figure 8 pattern. The adjoining plaque implies that by standing slightly left or right of the zodiac center line, you can adjust your shadow time to show civil time.

    Unfortunately, this is NOT correct. One should straddle the central line to show solar time, which holds the longitude bias of 7 minutes plus the east-west time variance of the sun (Equation of Time) that can be +/- 16 minutes difference. Stepping to the left or right of the zodiac central line does NOT correct the analemma EOT time difference.
