On the night of Oct 31, 2015 two bright Southern Taurid fireballs occurredover Poland, being one of the most spectacular bolides of this shower in recentyears. The first fireball - PF311015a Okonek - was detected by six videostations of Polish Fireball Network (PFN) and photographed by severalbystanders, allowing for precise determination of the trajectory and orbit ofthe event. The PF311015a Okonek entered Earth's atmosphere with the velocity of33.2 +\- 0.1 km/s and started to shine at height of 117.88 +\- 0.05 km. Themaximum brightness of -16.0 +\- 0.4 mag was reached at height of 82.5 +\- 0.1km. The trajectory of the fireball ended at height of 60.2 +\- 0.2 km withterminal velocity of 30.2 +\- 1.0 km/s.  The second fireball - PF311015b Ostrowite - was detected by six videostations of PFN. It started with velocity of 33.2 +\- 0.1 km/s at height of108.05 +\- 0.02 km. The peak brightness of -14.8 +\- 0.5 mag was recorded atheight of 82.2 +\- 0.1 km. The terminal velocity was 31.8 +\- 0.5 km/s and wasobserved at height of 57.86 +\- 0.03 km.  The orbits of both fireballs are similar not only to orbits of SouthernTaurids and comet 2P/Encke, but even closer resemblance was noticed for orbitsof 2005 UR and 2005 TF50 asteroids. Especially the former object is interestingbecause of its close flyby during spectacular Taurid maximum in 2005. Wecarried out a further search to investigate the possible genetic relationshipof Okonek and Ostrowite fireballs with both asteroids, that are considered tobe associated with Taurid complex. Although, we could not have confirmedunequivocally the relation between fireballs and these objects, we showed thatboth asteroids could be associated, having the same origin in a disruptionprocess that separates them.
