Sidereal 1.0 - is a small time utility for the Newton that automatically computes

and displays the local mean sidereal (astronomical) time based upon the home location that is set in the Time Zones application, and the time from the Newton's internal clock.  Sidereal should work with all versions of the Newton OS and requires approximately 6K of storage. Tap on the Sidereal icon in your Extras drawer to bring up the sidereal clock display. This display shows the current local mean sidereal time (LMST) in hours and minutes, and updates automatically.  By setting your "I am here" location in the Time Zones application and your local time in the Clock application,

Sidereal will compute and display the appropriate LMST.
