All satellite orbits maintain approximately the same orientation to the Sun and the stars during one day or more. If you see one at 9 pm and it has a period of around 90 minutes, two orbits later (three hours) it will be about 45 degrees west of you, at your latitude, and their local time is 9 pm. If the satellite is near-polar, all "inhabited" latitudes will have a pass near the same local time (but at my 59N the Sun would still be shining). If your times (EDT? and PDT) differ by 3h, a period near 90 (or 180) minutes would be implied, but more accurate times and positions are required to determine if it could be the same object (and which). ----------------------------------------------------------------- Unsubscribe from SeeSat-L by sending a message with 'unsubscribe' in the SUBJECT to SeeSat-L-request@lists.satellite.eu.org http://www2.satellite.eu.org/seesat/seesatindex.html
