Two our PhD students and myself took part at the SOHO 13 wokshop which was held at Palma de Mallorca (Balearic Islands, Spain) on 29 September - 3 October 2003. Thanks to the support of the SOC and ESNM-2 grant we were able to present 3 posters and to hear several very interesting lectures. Besides of this new cooperations and ideas seem to become a reality. Many thanks go to Prof. Ballester and his team who organized the workshop in an excellent way including a nice trip to Veldemosa and Son Marroch.
