3. Request the ephemeris:

This page is intended to be a "shortcut" to the JPL ephemeris generator for generating ephemerides of Io. It is a copy of the form you would see if, using the JPL ephemeris in the usual way, you had entered Io as the object, Kitt Peak as the observatory, today at hourly intervals as the time span, and the following as output quantities: astrometric RA and DEC, airmass, target angular diameter, observer sub-longitude and sub-latitude, solar sub-longitude and sub-latitude, north-pole position angle and distance, one-way light-time, speed wrt sun and observer, and earth-primary-obj angle. Clicking any button on this page will take you transparently into the actual JPL ephemeris generating system with these values preloaded. This page is not affiliated with JPL, so if you have questions about it, contact Carey Woodward at woodward@physics.wisc.edu. For questions about the ephemeris generator itself, follow the appropriate links above, or see the original footer below.
