Their online calculator "Apparent coordinates: topocentric ZD & Az, wrt local horizon" at http://aa.usno.navy.mil/data/docs/WebMICA_2.html gives me the data I want, but it will not allow me to see results for dates beyond May 01 2005 (as of today, April 02 2005). Maybe that's how they encourage MICA purchases (US$29.95 + shipping + duty + taxes)(?). Jim Thompson -------------------- Outgoing email scanned by Norton Antivirus
