A piece of a meteorite that had crashed through the roof of a cottage house was find in the central Oslo quarter Rodelřkka at the beginning of March 2012. Some days later the second discovery in the melting snow of Ekebergsletta hilltop plateau triggered the hunting for meteorites in almost all sides of Oslo. The pieces of third meteorite broken by cars and spread out by snowplow was discovered on the asphalt road side by Maciek Burski, the member of Polish Meteoritical Society. Later on the missing fragments of the Maciek’s most east find was collected by Meteoritical Section members of Comet and Meteor Workshop (PKiM) with the help of local meteoritical authorities. The total mass of this unobserved fall is 6.22 kg in five pieces spread out in the eight km-long strewnfield with 200 g and 4.65 kg meteorites on the opposite ends. The Meteorite is not classified yet but unofficial information is “breccia H3-4”.

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.

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.

The Polish Fireball Network (PFN) is a project to monitor regularly the sky over Poland in order to detect bright fireballs. In 2016 the 72 PFN cameras recorded 100 389 meteor events. Using these data and the UFOOrbit software 19 087 trajectories and orbits were calculated. In the following years we are planning intensive modernization of the PFN network including installation of dozens of new digital cameras.

Polish Fireball Network (PFN) to projekt polegający na regularnym monitorowaniu nieba nad Polską w celu zaobserwowania jasnych meteorów i bolidów. W 2016 roku 72 kamery PFN zarejestrowały 100 389 meteorów. Za pomocą tych danych i oprogramowania UFOOrbit obliczono 19 087 trajektorie i orbity. W kolejnych latach planujemy intensywną modernizację sieci PFN, w tym instalację kilkudziesięciu nowych kamer cyfrowych.

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.
