1A10.49 - 24 Hr Sidereal Clock
Google "Sidereal Time" and once you enter in the correct Longitude for this building you will be able to set the clocks. Van Allen Hall will be 91.31 W Longitude. Our telescope pad in Arizona is 110.36 W Longitude.
The digital sidereal clock runs on 12 Volts. Make sure you connect the leads to the battery correctly as connecting them backward will destroy the clock.
