It seems to me the few replies on SeeSat-L are shooting at different targets (!) - neither telescopic tracking nor known objects was asked for. To watch an approximately known track with binoculars or at "one-power" I simply copy an elset 2-11 times and add fractions of 360 to the AOP value. Example: 221.0195 and 301.0195 or 291, 321, 351, 021, 051.... instead of 261.0195 in the following elset: USA 193 A 5.0 2.5 0.0 4.3 v 250 X 257 km 1 29651U 06057A 08049.03290930 .00227439 00000-0 27958-3 0 02 2 29651 58.5131 39.7259 0005095 99.1484 261.0195 16.07330305 09 The tracking tool by John Dormer may be a useful addition though. Although existing telescope drivers allow scanning the track, I'm not certain they also compensate for Earth's rotation with (large) timing errors (which CosaTrak - used by Greg Roberts and Lutz Schindler) The Meade Autostar native satellite tracking is inaccurate AND does not include rotation; Boshart's SatTrack is accurate, but I haven't verified large errors. ----- Original Message ----- From: <k4hsm@knology.net> Is there any way to predict when the orbital plane of USA193 is over an area? So we can look for possible debris not yet recorded or too small to track? I realize we may not see small debris re-enter, but it might give me an excuse to get out of the house... ------------------------------------------------------------------------- Subscribe/Unsubscribe info, Frequently Asked Questions, SeeSat-L archive: http://www.satobs.org/seesat/seesatindex.html
