The conference room is in this historical building of the Meudon Observatory. The Meudon Observatory is located outskirt of Paris.

In the dome of the building 83 cm and 62 cm refractors are installed, which are over 100 years old.

I gave Doug Snyder, an independent discoverer of C/2002 E2 Snyder-Murakami, calligraphy of my own writing. It is a poem created by the late Minoru Honda;
A star, it is in the sky
It is in your mind
And it shines by itself

A minor planet discovered by Tichy has been named Biver (26969) after Nicolas Biver, the chairman of the workshop. Biver received the plate on the minor planet from Milos Tichy.

Reception was held at the Paris Observatory, near the center of Paris.
In front of the Paris Observatory there is a statue of Le Verrier, who predicted the position of unknown planet Neptune based on the perturbation of Uranus orbit.

We could observe the entire phenomenon under the perfect sky condition.
