    Hi Ted and Frits
    Ted Molczan pointed out to me that ISS was visible.
    
    I used day 190 TLE.
    I now recall ISS made orbitcorrections early this month.
    
    Using day 177 TLE I got:
    98- 67A         22h00m26s  14h44  + 3  222  33    363    628   64  -0.4
                    22h00m56s  15h57  + 9  203  45    363    502   52  -1.1
                    22h01m26s  17h42  +15  164  52    363    452   41  -1.5
                    22h01m57s  19h33  +18  125  45    363    502   43  -1.2
    
    So it was indeed ISS that was seen.
