Sommers-Bausch Observatory (SBO) on the University of Colorado Boulder campus is operated by the Department of Astrophysical and Planetary Sciences (APS) to provide observational experience for undergraduate students and hands-on training in astronomical observations and instrumentation for departmental majors and graduate students.
The telescope is slightly over 1/4 mile (1,357 feet) north of the Earth's 40th Parallel of Latitude (the street named Baseline which runs east-west through the southern portion of the city of Boulder).
Sommers-Bausch Observatory is now listed with the IAU and MPC with an Observatory Code of 463. SBO users who file a report with the International Astronomical Union or its Minor Planet Center should include the code for identification.
The Observatory lies 7 hours, 1 minute, 3.24 seconds of time west of the Prime Meridian, hence our Local Sidereal Time trails that of Greenwich England by 7h 1m 3s.
Our Local Mean Solar Time lags behind Mountain Standard Time (mean time at the 105th meridian) by 63 seconds. Subtract 1 minute and 3 seconds from the civil timezone MST to obtain the Local Mean Solar Time at SBO.
Sundial time is the true solar time at our location equal to the hour angle of the Sun (plus 12 hours since LAST begins at midnight rather than noontime). From your adjustment for Mean Solar Time, subtract the appropriate value from the Equation of Time chart to obtain the SBO Local Apparent Solar Time.
