During the evening and until 4 a.m. at night after the instrumentally detected meteorite fall Skytinel’s founder Mateusz \u017bmija worked on a first analysis of data provided by 24 Skytinel cameras to determine a preliminary fall area of meteorites. This area was then searched by 26 people on 19 April, but in vain. To improve the precision of the calculations Skytinel began to cooperate with the Institute of Astronomy of the Czech Academy of Sciences at the beginning of the following week. On 22 April after another trajectory and dark flight calculation, now including Skytinel camera data, Pavel Spurn\u00fd, Ji\u0159\u00ed Borovi\u010dka and Luk\u00e1\u0161 Shrben\u00fd provided the information to Mateusz \u017bmija that a single 2.7-kilogram mass could have fallen. Dr. Radmila Bro\u017ekov\u00e1 from the Czech Hydrometeorological Institute had provided the important high-altitude wind data. With this new and precise information Mateusz \u017bmija and G\u00e1bor K\u0151v\u00e1g\u00f3 re-simulated the impact of a 2.5\u20133 kg meteorite, which significantly narrowed their formerly calculated search area to a smaller one within, which covered only approximately 300 x 200 metres. At around 13:30 CEST on 22 April an oriented triangular-shaped 2869-gram meteorite mass (14.5 x 11.5 x 6.5 cm) was found by Anna Walczak accompanied by her husband Pawe\u0142, two members of a team of up to 26 people associated with the Skytinel network who searched the area on 19 and 22 April. The meteorite was found at the bottom of an approximately 40 cm deep elliptical hole (20 x 10 cm) covered with about 10 centimeters of loose soil. On 24 April 2026 (16:30 CEST) Pavel Spurn\u00fd, Ji\u0159\u00ed Borovi\u010dka and Luk\u00e1\u0161 Shrben\u00fd of the Institute of Astronomy of the Czech Academy of Sciences published the find (LINK<\/a>) together with Skytinel (LINK<\/a>). The exact location of the meteorite fall within Zadzim commune has not been disclosed yet, but it might be a few kilometres northeast of Zadzim, somewhere around location 51\u00b047’53.7″N, 18\u00b054’43.7″E<\/a>. It is assumed that only this one meteorite mass fell and that there are most likely no other masses to be found in the area. The two finders can keep the meteorite. They have agreed that a type specimen can be cut for classification. They reportedly would like to have the meteorite exhibited to the public in a museum to serve for educational purposes. Just before midnight on 24 April gamma spectrometry analyses on the meteorite started at National Centre for Nuclear Research (NCBJ) in \u015awierk. Measuring short-lived radioisotopes are very important to determine a very short terrestrial age of the find and thus confirm that the found mass can without any doubt be attributed to the bolide on 17 April 2026. Additionally, the meteorite’s cosmic-ray exposure age can be measured in this way. This quick recovery of the meteorite is another great success of Mateusz \u017bmija and his Skytinel camera network and the experienced team of the Institute of Astronomy of the Czech Academy of Sciences.<\/p>\n\n\n\n

“Przykryty by\u0142 jeszcze na tych 40 centymetrach tak\u0105 niedu\u017c\u0105 warstw\u0105 Ziemi. Kiedy zajrzeli\u015bmy w dziur\u0119 okaza\u0142o si\u0119, \u017ce faktycznie b\u0142yszczy tam co\u015b, co wygl\u0105da\u0142o jak kawa\u0142ek metalu.” (Anna Walczak) <\/p>\n\n\n\n

(It lay buried at a depth of 40 centimeters, covered by a relatively thin layer of soil. When we peered into the hole, we saw something glinting inside\u2014something that looked unmistakably like a piece of metal.)<\/p>\n\n\n\n

The bolide<\/p>\n\n\n\n

The meteoroid with a mass of about 100 kilograms began its luminous trail at an altitude of ~84 km with an entry speed of ~13 km\/s moving southeast in a relatively steep trajectory (69\u00b0 to the earth’s surface). The bolide’s almost 7-second luminous trail was about 75 kilometres long, penetrated deep into the atmosphere and ended 14 kilometres above the ground.
