8A10.40 - Sidereal Time
The sidereal clocks will need to be powered up and set before class. Use one of the small 12 volt lead-acid batteries to power the digital clock. MAKE SURE YOU CONNECT THE BATTERY TO THE DIGITAL CLOCK WITH THE CORRECT ORIENTATION AS REVERSING THE LEADS WILL DESTROY THE CLOCK. You can also add a regular clock to show the difference between the normal time of day and the sidereal time.
