- Description:
- The bronze cylindrical dial is 5-foot in diameter. The dial reads time and date from a rod gnomon cast onto an engraved, equatorial band. The dial shows date bands and solar time corrected for longitude (3 min 17s west of the 105 degree meridian). The dial is accurate to about one minute. At the noon hour line is an analemma showing the correction to mean time. The armillary sphere was designed and built by observatory staff members Dr. Don Neidig, Scott Gregory, and Mitchell Davis.
