Astronomical calculations
Positions on this site are computed with the Swiss Ephemeris, © Astrodienst AG, Switzerland.
The Swiss Ephemeris is used here under the GNU Affero General Public License, version 3. Because this service runs that software over a network, AGPL section 13 gives users of this service the right to receive the corresponding source code for it. Write to us and we will provide it.
