TL;DR
This study links a fireball over Poland to near-Earth asteroids 2010 TB54 and 2010 SX11 based on orbital similarities, suggesting a common origin and potential meteorite fall site.
Contribution
It provides the first detailed analysis connecting a fireball to specific near-Earth asteroids through orbit comparison and atmospheric data.
Findings
Fireball's orbit is similar to asteroid 2010 TB54.
Another asteroid, 2010 SX11, has an even more similar orbit.
Meteorite fragments could survive atmospheric entry and reach the ground.
Abstract
On 2010 October 13, the Apollo type 20-meter asteroid 2010 TB54 passed within 6.1 lunar distances from the Earth. On the same date, but 11.4 hours earlier, exactly at 02:52:32 UT, the sky over central Poland was illuminated by -8.6 magnitude PF131010 Ciechanow fireball. The trajectory and orbit of the fireball was computed using multi-station data of Polish Fireball Network (PFN). The results indicate that the orbit of the meteoroid which caused the PF131010 fireball is similar to the orbit of 2010 TB54 asteroid and both bodies may be related. Moreover, two days before appearance of Ciechanow fireball another small asteroid denoted as 2010 SX11 passed close to the Earth-Moon system. Its orbit is even more similar to the orbit of Ciechanow fireball parent body than in case of 2010 TB54. The PF131010 Ciechanow entered Earth's atmosphere with the velocity of 12.9 +\- 0.2 km/s and started…
