We are interested in meteorites, planetary geology, composition of asteroids and comets. Specifically we dwell into the comet age evaluation based on crystallinity, if asteroids can possess their own magnetic dynamo, and what is the nature of geophysical fields on planets like Mars, Jupiter, Mercury, including some of their moons. Growing interest is about fall of meteorites on our planet, and wha

June 17-24, 2013; Travel to Russia to measure magnetic anomalies at the bottom of Chebarkul lake. Participants were Darja Kawasumiova, Gunther Kletetschka, Ladislav Nabelek, and Jan Vyhnanek. Thanks to a cooperation with the Czech Technical University, especially help from doctoral student, Jan Vyhnanek, we were able to magnetically locate the meteorite. We used two GPS station system that allowed us assigning the position of the fragment more precisely.
