Miriade Ephemeris Generator

Query form

This Web form is a user interface to the VO-compliant Web service Miriade. It allows to compute positional ephemerides of planets, major natural satellites, asteroids and comets (Ephemerides tab), and to plot visibility charts of solar system objects to prepare observing nights (ViSiON tab). Fill in the form of your choice, and submit the query by clicking the button at the bottom of the page.

Observer location Change
Define the location of the observer by its IAU observatory code (string of 3 chars, e.g. 007 for Paris observatory, France), or enter the geographic coordinates of the location as 3 values separated by a space character: <longitude> <latitude> <altitude>. The longitude and latitude must be in degrees, respectively negative towards east and south, and the altitude must be in meters (e.g. -2.336537 +48.8364 132.0)

Mime type of the response:   PDF  HTML
Visibility criteria: 
Read the documentation to know how to enter the visibility criteria.
Example: el:{min:10.0}, elong:{sun:30.0,moon:5.0}, duration:10
to request a minimum elevation of 10°, a sun and moon elongation of 30° and 5°
with a minimum time span during which conditions are met of 10 minutes.
Sort entries: 
Read the documentation to know how to sort entries in tables (default: RA).
Example: dec to sort targets according to their declination,
or type>rate to sort according to target type, then according to apparent motion.
The sort option must be written at the last position.
