    I reported in a previous e-mail:
    >> I followed this object because the inclination was more like Seasat
    >> than like sun-synchronous satellites. It passed Edasich (iota Dra)
    >> 1 minute 28 seconds later, estimate RA 15:25 dec +59.0.

    On which Ted Molczan replied and asked:

    Unfortunately I am not able to check my original reporting. I recorded
    on my voicerecorder what I observed and did not add a time reference
    (in spoken form). Today I processed my observation night and had to
    listen to all my spoken comments. After I had to erase all those
    comments to get room for future comments. By this I can no longer
    check.
    I suggest do not regard the difference as precise. It was obtained
    from reading the time since I started the spoken comment. I may have
    misread for the second time.
    
    In my previous e-mail I did not mention the satellite's magnitude. It
    was about the same as star beta Ser ( Guide 8: +3.64) when being there
    and did not vary.
    
    Ted, thank you for your quick reply after analysis. I appreciate this very much.
