On recommendation of Ted did a plane scan to confirm that it had indeed changed. This time I had excellant conditions and found the satellite was running about 5 minutes early and no change appears to have taken place in the orbit. (2) Times reported as integer seconds are from the Meade camera, whilst the other observations are from the video camera. (3) Good thing I "found" it again as we would have all then gone on a "wild goose chase" looking for it!!!
