You can use SkyMap (or some other program with accurate shadow computations) to show these points for any time/place. If you know the satellites nearby at the time, predict them. If you want to use a file of "all" - or "all" geosynch - the output from a text based program like HighFly becomes unwieldly, and for SkyMap you should either set the max perigee to 38000 km and/or range to whatever the operational sats have near the desired time/place (e.g. 37100-37500 km around 08:00 UTC), and a short time frame (e.g. 00:30) I'll send Jeff an example or two, and if still wanted I can do more/all. /Björn ----- Original Message ----- > Could someone provide to me the Earth's two > shadow edge points at the Clarke Orbit for Feb 27 at > 4:00UT, 6:40UT, and 8:00 UT in RA and Dec?
