In the Meteor Physics Group, we observe meteors and we work on theoretical interpretations of meteor observations.
The basic observing system is the European fireball network. It is a network of stations that records bright fireballs.
If you have seen a bright fireball, please report it. Here you can find the fireball reporting form.
An article on meteor clusters was published in the journal Icarus
The paper on thermal stress in Geminids was published in Astronomy & Astrophysics
Here is an article on how to check if you have found a real meteorite.
