The first meteorite (92.8 g, dry) was found by Maksymilian Jakubczak at 10:10 (CET) on 22 February 2025. At 12:30 (CET) on the same day a 257.4-gram mass was found by Krzysztof Oleszczuk and a 48.02-gram specimen by Wojciech Burzy\u0144ski in or near the Drel\u00f3w commune in the Bia\u0142a Podlaska district. The 257.4-gram mass has been sent to the National Center for Nuclear Research (NCBJ) for short-lived radioisotope analysis. On 23 February at 9:20 CET a fourth specimen weighing 293.2 grams was found by Daria Klimek and Mariusz Krall and at 12:30 CET a 517.07-gram specimen was found by Wiktor Hajwos, son of the SN21 station operator, as member of the search group together with Marcin Hajwos (SN14 station), Artur Ja\u015bkiewicz (SN33 station), Dariusz Skierski, and Mateusz Zmija (SN01 station). The 517.07-gram specimen has been sent to the National Centre for Nuclear Research (NCBJ) in Otwock in Poland for short-lived radioisotope analysis. More meteorites were found on 23 February 2025, including a 25.59-gram specimen, found at 15:55 (CET) by Gabriela Najman, a 44.5-gram mass found by Marcin \u017bywczak and a 104-gram fragment found by Piotr Po\u0107wierz. On 24 February Pawe\u0142 Walczak (SN12 station) found a 23-gram mass while searching together with his teen son and Mateusz \u017bmija. It has been sent to the Rzesz\u00f3w University of Technology for analysis. On the same day at ~15:00 CET a ~28-gram specimen was found by the team Filip Nikodem, Micha\u0142 Nebelski and Andrzej Owczarzak. Furthermore, two additional masses were found on 24 February. Tomasz \u017bywczak found a 26.5-gram specimen and Kryspin Kmieciak found a 77-gram mass, of which 23.73 grams (in three fragments) as type specimen have been sent to the Faculty of Natural Sciences, University of Silesia in Katowice for analyses. On 25 February Sylwester Wojda found a 462-gram specimen and Jaros\u0142aw Morys (SN02 station) found a 115-gram specimen which has been sent to sent to Institute of Nuclear Physics of the Polish Academy of Sciences (IFJ PAN) in Krak\u00f3w). On the same day Dr. Zolt\u00e1n Balla found a 179-gram mass accompanied by Bir\u00f3 Zs\u00f3fia and K\u0151v\u00e1g\u00f3 G\u00e1bor. On 26 February the following finds were reportedly made: 32 grams by Arek Bingoraj, 62 g by Jaros\u0142aw Morys (also sent to Institute of Nuclear Physics of the Polish Academy of Sciences (IFJ PAN) in Krak\u00f3w), 33.95 g (at 14:09 CET) by Szymon Koz\u0142owski and Rafa\u0142 M\u0105ka, 18 g by Andrzej Owczarzak, 66.6 by Micha\u0142 Nebelski, 290 g in three fragments by Kryspin Kmieciak and 58 g by Filip Nikodem. On 27 February 2025 these masses were reportedly found: 35 g by Wojciech Jachymek, 47 g by Leon Thann, 17 g by Daria Klimek and Mariusz Krall and 105 g by Marcin Pietryszyk. On 28 February Micha\u0142 Nebelski found a 64-gram fragment, Pawe\u0142 Zar\u0119ba found an 18.48-gram specimen and Martyna Motylska found a 23 gram mass. On 1 March Filip Nikodem found an 18-gram specimen accompanied by Andrzej Owczarzak and Micha\u0142 Nebelski. On 2 March Marek Nikodem found a 16-gram specimen and on 3 March a ~10-gram specimen was found by Andrzej Owczarzak. On the same day Leon Thann found a 22-gram fragment and Filip Nikodem (~3g) and Andrzej Owczarzak (two fragments weighing ~43g) found three fragments of a ~46.24-gram mass. On 4 March Micha\u0142 Nebelski found a 4.9-gram specimen and Jaros\u0142aw Morys found a ~10-gram mass. On the same day two other finds were made: 8.735 g by Andrzej Owczarzak and 14.12 g by Aleksander B\u0142asiak. The following finds were made on 5 March 2025: 3.65 g by Mateusz \u017bmija, 40.92 g by Patryk Kosa\u0142ka and Oliwia Winnik, 40 g by Tomasz ‘Aurora’ \u017bywczak. On 6 March Filip Nikodem found a 93-gram fragment which fits perfectly to the 40.92-gram fragment found by Patryk Kosa\u0142ka and Oliwia Winnik, which is exhibited at Jagiellonian University’s Nature Education Center. On the same day Andrzej Owczarzak found a 7.5-gram specimen and Gabriela Najman found a 1.1-gram specimen at 10:30 CET. On 7 March Micha\u0142 Nebelski found a 31-gram mass. On 8 March Marcin Hajwos’s wife Adrianna Hajwos found a 14.4-gram specimen. Furthermore this find has been reported online: 3.6 g by Maciej \u0141ab\u0119cki. Analyses for a classification of this meteorite fall are being performed at the University of Silesia in Katowice, and at the Faculty of Natural Sciences, by Prof. Krzysztof Szopa and Agnieszka Mirek.<\/p>\n\n\n\n

The luminous trail of the bolide became visible above Ostr\u00f3w Lubelski at an altitude of about 82.5 kilometres with a meteoroid entry velocity of 13km\/s. It was heading north and its luminous trail ended at an altitude of about 19.5 kilometres above an area 12 km away from Mi\u0119dzyrzec Podlaski. The final fragmentation of the meteoroid reportedly happened at an altitude of about 19.5 kilometres at a pressure of 4 MPa according to calculations. Tomek Walesiak used already published Skytinel<\/a> trajectory data, calculated by Mateusz \u017bmija, coordinator and founder of Skytinel Network (initiated only 10 months before this fall), and published his strewn field calculations on 19 February 2025. For the Skytinel Network Mateusz \u017bmija and K\u0151v\u00e1g\u00f3 G\u00e1bor, supported by Prof. Szymon Koz\u0142owski (Astronomical Observatory of the University of Warsaw, Poland), had already calculated a preliminary search area which is approximately 7 km long and 0.3-1.3 km wide (for hypothetical meteorite masses from 1 kg to 10 g). Due to strong high-altitude winds and the moderately high entry angle of the event (55\u00b0 to the horizon), falling meteorites masses were moved far backward and eastward from the trajectory endpoint. For the calculation of the atmospheric trajectory and the ~14-square-kilometer strewn field the following Skytinel fireball network cameras were used: SN07 in Bodzentyn (Mateusz Roman), SN08 in Oleszyce (Szymon Ozimek), SN14 in Warsaw (Marcin Hajwos), SN21 in Olsztyn (Olsztyn Planetarium and Astronomical Observatory) and SN28 in Elbl\u0105g (Krzysztof Kida). All in all ten Skytinel cameras captured the bolide. The meteoroid’s preatmospheric orbit was inclined at an angle of 2.9 \u00b0 to the ecliptic plane, and the meteoroid was 2.91 AU from the Sun. Skytinel’s Mateusz \u017bmija used an additional, close video from a surveillance camera sent by Sylwester Szubi\u0144ski to specify the parameters of the main mass of the fall. His calculations revealed that it had to weigh about 600 g (assuming a meteorite density of 3.2 g\/cm\u00b3). The designated small sub-area for the main mass in the northern part of the strewn field was searched the following day and the search resulted in the finding of the 517.07-gram main mass found by Wiktor Hajwos and his team (see above). On 20 October 2025 the fall was registered in the Meteoritical Bulletin as Drel\u00f3w<\/strong><\/a> (L6)<\/p>\n\n\n\n
