The Antonin meteorite fell on July 15, 2021 in Wielkopolska Voivodeship. Its fall was recorded by fireball camera network and the meteorite specimen was recovered soon after, during a dedicated search expedition. Main mass of Antonin was provided for scientific research relatively quickly after recovery, thanks to which the studies of cosmogenic radionuclide concentrations were carried out in the g spectrometry laboratory at the National Center for Nuclear Research in Otwock/Świerk. The analyses revealed concentration of 7Be and the traces of the cosmogenic radionuclides of 48V and 51Cr, whose half-lives are in the range of 15–28 days, clearly confirming the relationship of the specimen with the observed fireball. The relatively high concentrations of 58Co, 56Co, 46Sc, 57Co and 54Mn (half-lives of several months) also confirm the recent fall of the specimen. Additionally, collected radionuclide data allow to estimate pre-atmospheric size of the meteoroid. Distribution of 60Co and 26Al indicates a meteoroid chunk with a radius of 20–25 cm. The result of 26Al measurement suggests that the investigated meteorite fragment comes from a rather shallow depth of this meteoroid. In addition, the original mass of the meteoroid from which the Antonin meteorite originated was estimated to be less than 100 kg, most likely 70 kg.

The Polish Fireball Network (PFN), has been undergoing continuous development. Since then, several large grants have been obtained, which were at least partly used for modernization purposes. In recent years, two more grants have been obtained, which allowed for the expansion and modification of the existing PFN infrastructure. In 2021, the PFN76 Kozienice was modernized, but also the PFN14 Zielona Góra station was reactivated and the new PFN77 Suhora station was launched in 2022. Thanks to these improvements, the tracking of meteoroids entering the Earth Atmosphere above Poland became more accurate, which facilitates the search for meteorites and increases the chances of finding new fresh meteorites in Poland. On the night of May 10, 2021, PFN stations registered an exceptionally slow bolide. The phenomenon named PF100521 Wykrot appeared over central Poland in the Mazowieckie Voivodeship at 21:32 UT and calculations showed that some meteorites may have fallen. This phenomenon was used to conduct a series of analyzes to show how observational uncertainties affect the final results. Two variants of the results are presented in this work.

The Meteorite Section was created in 2010 on demand of Polish Fireball Network (PFN) for the meteorite searching and investigation purposes. The main task of the Section is to find the meteorites dropped from bolides registered by the Polish Fireball Network. Each year, the PFN registers several meteorite falls within our country and meteorite strewnfield inspections must be carried out at least for the masses of above 300 g estimated with the PyFN software. Only last year the PFN organized several search campaigns. Two of them are presented in the publication.

Since 2010, the Meteorite Section of the Comet and Meteor Workshop (PKiM) has been systematically organizing exploratory expeditions to selected meteorite strewn fields, calculated from bolides registered with the Polish Fireball Network (PFN). Some of the expeditions organized in the period of 2018–2020, after the phenomena PF140118, PF070119, EN050120 and PF310720 are reported. All these phenomena have a common feature, they reach beyond the borders of Poland – either the analysis was developed in cooperation with the European Fireball Network (EN) or the meteorite fall took place abroad. It is clear that meteor phenomena have no boundaries and for positive research results in near-Earth space science a European cooperation is highly recommended. Many meteorites fallen from the bolides registered in the PFN are still in the strewn field waiting to be discovered. The article presents a study of the most important phenomena happened in two last years, and it is also a hint where to look for meteorites in Europe.

The Polish Fireball Network (PFN) associated in Comets and Meteors Workshop monitors the sky over Poland regularly for 15 years and registers the bright fireballs over the whole country (Olech 2006; Wiśniewski 2017). Every year we observe a few meteorite falls but due to weather conditions some data are not sufficient for proper strewnfield calculations. In the collaboration with the European Fireball Network the whole territory of Poland is monitored almost regardless of the weather. The publication describes the bolide phenomena characterized by distinctive meteorite falls, so the strewnfield indicated here should become the target of further exploration expeditions.
