PLANETS: Calculates positions
of the Sun, Moon and planets from a chosen site. JPL DE405 Ephemerides also available
.
Calibrators: List available calibrators given an LST and/or flux range.
Ephemeris Tool: Determine Rise/Set times of objects. Note: quoted positions for planets have a precision of about 2 arcmin.
Please use the PLANETS tool above if you require higher accuracy. The old 'COORD' utility is here.
Obsability Tool: which produces time vs. elevation charts for multiple objects.
