Sunday, June 16, participants started to arrive at the conference site at Hotel Tatra in Bratislava. Registrations started with a welcome drink that offered excellent circumstances to talk with many people about the latest news and challenges in the meteor world.
A conference is more than just a series of oral and poster presentations, most of the time is spent on informal contacts and private discussions with meteor specialists. In this report we limit the information to the oral presentations with a link to the abstracts delivered.
Monday June 17
Monday June 17 the first lecture sessions were planned. The conference was opened by the dean of Faculty Mathematics, Physics and Informatics, Comenius University in Bratislava. The president of IAU commission F1, Diego Janches and Juraj Toth, Head of the LOC welcomed everyone to the 10th meeting of Meteoroids. At this occasion some memories were refreshed with photographs of the very first Meteoroids conference that took place 17 years ago in Smolenice during July 1992, also in Slovakia.
Galina Ryabova announced the publication of a new standard work on meteor astronomy which can be temporary ordered with a 20% reduction. More about this Meteoroids book can be found on MeteorNews.
