    Re: Celestial Navigation Data from USNO--alternative
    From: Jim Rives

    Just a quick question... I just came across my USNO Multiyear Interactive Computer Almanac (MICA) CD which seems to have been put out in 2005.   Well, we still have CD readers, for the time being.  I was directed to http://www.usno.navy.mil/USNO/astronomical-applications/publications/circ-181 for updates to delta-T, which no longer works.  When did USNO shut down the almanac service?  Is there an alternative?  

    Thanks, 

    Jim
