     Grzegorz,
     
     For your location on 20 May, the NOSS 2-3 rocket passed near Spica in 
     the south moving toward the northeast. I've logged NOSS 2-3r with 
     flash duration shorter than 8 seconds, but the rest of your 
     description fits this object. NOSS 2-3r is relatively bright. At 
     culmination it was about 550 km from you which means it was capable of 
     displaying near mag -1 flashes.
     
     
     For 53.38N  14.83E   on 20 May 1998:

     By your message I wasn't sure where in its path it was at 2111 UT. The TLE 
     I used is nearly two weeks old which may account for a small time 
     difference.

Hello,
A strange satellite was observed at 21:11 UT, May 20. It passed Spica 
low in southern sky and moved north-notheast. It's brightness was 
changing for 3 to -1 mag. with period of about 8 seconds. Maybe someone 
knows what that was?
                                                                 Thanks,
                                                     Grzegorz Koralewski
