Welcome! Yes, location in the sky is usually more accurate if you can relate to "known" stars, or attach an annotated sky map (NB seesat-L hides attachments, as well as HTML code, but members can retrieve them anyway) For accurate observations, we usually estimate the fraction were the satellite crosses a line of two (close) stars. Likewise, direction of motion is more reliable if you imagine the face of a watch where the satellite position is given - so a satellite moving horizontally is "9 o'clock" or 270 degrees. And it is helpful if you include your coordinates in degrees , to (at least) two decimals. I guessed 49.317N,123.067W Above all, time (in UT helps the world community) to the nearest minute. In a span of an hour, we may have hundreds of potential satellites to ignore. But it seems the sky would have been too bright for a "normal" satellite before 8:30 or even 9PM ! You can try to identify satellites yourself, or get a sky map to complement your ID request, at Heavens-Above: http://www.heavens-above.com/lat=49.317&lng=-123.067&alt=46&loc=North+Vancouver Example : In the map http://www.heavens-above.com/PassDetails.asp?ORA=290.5&ODec=25.6&SatID=25721&lat=49.317&lng=-123.067&TZ=PST&Mouse=?33,287&loc=North+Vancouver&Date=40784.19 (let me know if you don't find out how to get to these maps for other times/objects) you could write 'passed R.A. 22:45 Dec. +23 (or describe the stars) in direction 7:30 on a clock (or 220 degrees) 2011/9/6 Derrick MacPherson <derrickmacpherson@gmail.com>: >...This all happened in about ten > seconds, I called to our other friend to take a look and the first object > was no longer visible..
