Description:
  • A 2 meter diameter ring equatorial dial of welded anodized aluminum plate. The dial face shows Arabic numerals with hour and quarter-hour marks. This face can be moved for longitude correction and DST, and was originally adjusted to correct periodically for EOT. In 2009, the original straight gnomon was replaced with an analemmic gnomon, eliminating the need to adjust or correct for EOT.
