Dear friend, I have represented the venus analemma for 2 next years as follow pos = $GeoLocation zone = $TimeZone analemmavenus = Table[{ AstronomicalData["Venus", {"Azimuth", {2011, 1, i, 6}, pos}, TimeZone -> zone], AstronomicalData["Venus", {"Altitude", {2011, 1, i, 6}, pos}, TimeZone -> zone]}, {i, 1, 2*365.25, 10}]; Graphics[{Orange, Point[analemmavenus]}, Frame -> True, FrameLabel -> {"azimut", "altitud"}] Is it taken into account when the planet is behind the Sun? It the answer is negative. How can be taken into account that a planet is behind the Sun? HNY Guillermo
