Novo Mesto

Meteorite fall (720 g, L5, S5) near Novo Mesto, Lower Carniola, Slovenia at 09:30:34 UT on 28 February 2020

The first meteorite, an ordinary chondrite (L5, S5), was found accidentally by Gregor Kos and his son at location 45°49’00.5″N, 15°06’44.9″E in the village Prečna, near Novo Mesto, Slovenia at around 3:30 p.m. on 4 March. Kos claims he found the meteorite weighing 203 grams in the driveway of his home but did not inform Bojan Ambrožič until 7 March when he heard about a meteorite search campaign organized by Ambrožič. On the same day the meteorite was given to Dr. Miha Jerška from the Museum of Natural History of Slovenia. The meteorite was revealed to the public at a press conference in the Museum of Natural History on 8 March. On 12 March it was announced that another meteorite had been found. On 10 March a 469-gram specimen was found near Novo Mesto by an anonymous finder at an undisclosed location. On 14 March a 48-gram specimen, now named ‘Gaja’, was found by the girl Gaja Urek Ekart after 45 minutes of searching together with her mother in the forest northwest of Novo Mesto, near the Adria Mobil factory.

Since the meteorites are similar to other recent chondritic finds it is strongly advised to analyse the short-lived radionuclides of these meteorites to determine their terrestrial age and thus confirm that they are definitely related to the bolide on 28 February 2020. On 3 July 2020 the fall was officially registered in the Meteoritical Bulletin as Novo Mesto (L5,S5, W0/1).
