On September 12 , 2016 , at 21:44:07 UT , a -9.2 \pm 0.5 mag fireball appeared over northeastern Poland .
The precise orbit and atmospheric trajectory of the event is presented , based on the data collected by six video stations of Polish Fireball Network ( PFN ) .
The PF120916 Piecki fireball entered Earth ’ s atmosphere with the velocity of 16.7 \pm 0.3 km/s and started to shine at height of 81.9 \pm 0.3 km .
Clear deceleration started after first three seconds of flight , and the terminal velocity of the meteor was only 5.0 \pm 0.3 km/s at height of 26.0 \pm 0.2 km .
Such a low value of terminal velocity indicates that fragments with total mass of around 10 - 15 kg could survive the atmospheric passage and cause fall of the meteorites .
The predicted area of possible meteorite impact is computed and it is located south of Reszel city at Warmian-Masurian region .
The impact area was extensively searched by experienced groups of meteorite hunters but without any success .
