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 paper presents the circumstances and data accompanying meteorite falls in recent years. The study contains descriptions of 21 falls observed in 2020 and 15 falls in 2021. These phenomena took place on all continents, except the polar regions. In conclusion, this work is a collection of several dozen stories about freshly fallen meteorites. They show many aspects connected with the observations and the hunting for new specimens.

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.

In 2022, there were ten meteorites found worldwide after fresh falls. These are primarily ordinary chondrites, but one achondrite fall was also recorded. Meteorite falls occurred in the United States (3) and China (2) but also in Algeria, Brazil, Slovakia, India, and the Philippines. This paper shows how these meteorites were found and provides conclusions before future searches.

This scientific paper aims to systematize knowledge about the circumstances of meteorite falls in 2018. Eight of them were officially confirmed by The Meteoritical Society: Hamburg (USA), Ablaketka (Kazakhstan), Aba Pan (Nigeria), Mangui (China), Ozerki (Russia), Renchen (Germany), Gueltat Zemmour (Morocco), Komaki (Japan). Seven more have not yet been classified: Central Kalahari (Botswana), Glendale (USA), Benenitra (Madagascar), Bhakkar (Pakistan), Ghadamis (Libya), Elkouran (Morocco) and meteorite fall from the Sahara Desert. It turns out that the most numerous group of meteorite falls in 2018 were L6 chondrites. There were no iron or stony-iron falls. The author collected information from many different sources. He analyzed entries in the MetBull catalog, publications in social media and press reports in order to compare them with official data from previous years. In this way, he tries to prove that although the circumstances of each meteorite fall are different, coherent conclusions can be drawn from them, and these can help meteorite researchers, for example, in verifying eyewitness accounts.

This scientific paper is a summary of the meteorite falls in 2017: Broek in Waterland (Holland), Tres Irmaos (Brazil), Serra Pelada (Brazil) and Kheneg Ljouâd (Morocco). The study also includes a section about unconfirmed falls, such as Puya Medio (Colombia), Mukundpura (India), Crawford Bay (Canada) and Sadiya (India). The vast majority of these specimens is ordinary chondrites of the L and LL groups. Only Serra Pelada meteorite turned out to be eucrite and Mukundpura is suspected to be carbonaceous chondrite. The author collects and organizes basic information about these findings and compares the latest data with statistics from previous years. The description of the circumstances of finding meteorites are brief and maintained in the popular-scientific tone. The text also includes a set of fireballs and bolides that could end with a meteorite fall. Among them is also a bolide that was visible from Poland. The thesis resembles the criteria for dividing meteors and notes the differences in their naming. It is extended by analogies and comparisons that make possible to look at the issues from different perspectives: from the statistical, through the media, to the historical one.

In 2019 two meteorite showers occurred on Earth, which ended with the fall of hundreds of fragments in Cuba and Costa Rica. Apart from them, meteorites with a total weight of probably less than 10 kg landed in Algeria, Morocco, Iran, India, and Germany. This work is another summary of the year in terms of meteorite falls. It includes information on the circumstances of these phenomena and their scientific consequences. The author collected information from many sources, especially the media and meteorite hunters, to describe in a brief form how the meteorites fell last year. The purpose of his work is to gather basic and proven knowledge, which can serve as an inspiration to further explore the history of meteorites, own meteorite hunting, and draw the attention of researchers to interesting falls in distant regions of the world.
