Ausführliche Daten über die Sichtbarkeit der ISS und anderer Satelliten am Himmel (von jedem beliebigen Ort) liefert: Heavens-Above (Chris Peat) The German Space Operations Centre (GSOC), which is part of the Deutsches Zentrum für Luft- und Raumfahrt (DLR), maintains a set of dynamic Web pages of satellite visibility predictions for ANY location on the Earth. Summary pages list all the upcoming visible passes, and detailed charts are available for each pass showing the satellite path against the stars. Predictions are also available for the dazzlingly bright flares which are regularly produced by the Iridium series of satellites. Heavens-Above (Chris Peat) Besonders interessant ist die Beobachtung der Iridium-Satelliten, die dem Mobilfunk dienen. Ihre Antennenflächen können das Sonnenlicht reflektieren, und bei passendem Winkel sieht der Beobachter für mehrere Sekunden ein Iridium Flare NIKON 24x36 mm camera, f=60 mm, 1:4, aperture 3.5, 200 ASA, exposure 20 s.   Iridium 25 flare on Aug. 5, 1999 Location: Latitude=51.617, Longitude=7.967 (Germany) Time: 22:31:42 CET Magn. -8, Elevation 49°, Azimuth 54° (NE) Distance to flare centre 2.6 km W, intensity at flare centre (magn.) -8 (data from "Heavens-Above (Chris Peat)", Chris Peat) NIKON 24x36 mm camera, f=60 mm, 1:4, aperture 3.5, 400 ASA, exposure 40 sec.
