The daylight fireball of June 25, 2022, leading to a meteorite fall and find near Pusté Úľany, Slovakia

L. Shrbený, Jiří Borovička, P. Spurný, Mike Hankey

Abstract We present detailed analysis of a daytime fireball observed on June 25, 2022, which is based on four instrumental video records. The atmospheric trajectory was observed from 69.5 to 21.8 km with a slope of 57.1 degrees to the surface. During …

Eta-Virginids: Another asteroidal meteoroid stream

Jiří Borovička, P. Spurný, P. Koten, Gabriel Borderes Motta et autres

Eta-Virginids is a less-known meteor shower active in March. We investigated the meteoroids of this shower using fireball data from the European Fireball Network supplemented by video data of faint meteors. We first derived the criteria for assigning meteors to this shower. …

Geminids are initially cracked by atmospheric thermal stress

Tomáš Henych, Jiří Borovička, D. Čapek, Vlastimil Vojáček et autres

Geminids have the highest bulk density of all major meteor showers and their mechanical strength appears to depend on their mass. They are also the most active annual shower, enabling detailed studies of the dependence of their physical and mechanical properties on …

A very young τ-Herculid meteor cluster observed during a 2022 shower outburst

Pavel Koten, D. Čapek, Juraj Tóth, L. Shrbený et autres

Context. To date, only a few meteor clusters have been instrumentally recorded. This means that every new detection is an important contribution to the understanding of these phenomena, which are thought to be evidence of the meteoroid fragmentation in the Solar System. …

The structure of κ Cygnid and August Draconid meteoroid streams

Jiří Borovička, P. Spurný, L. Kotková, Sirko Molau et autres

Meteoroid streams can be complex structures shaped by the processes of their formation and subsequent orbital evolution. The first step to understanding them is mapping their current stage. We used precise data from the European Fireball Network to disentangle the situation with …
