The IHY Newsletter – June 2008
****************************************************************
4th UN Basic Space Sciences-IHY Workshop Held in Bulgaria;
First Results from UNBSS-IHY Observatory Network Reported!
****************************************************************
The Fourth United Nations Basic Space Sciences Workshop on the International Heliophysical Year hosted by the Bulgarian Academy of Sciences during June 2-6, 2008 in Sozopol, Bulgaria. The workshop was attended by ~160 participants from more than 40 countries. The meeting was cosponsored by ESA, NASA, and JAXA along with the UN and the Solar-Terrestrial Influences Laboratory of the Bulgarian Academy of Sciences. J. Davila and N. Gopalswamy represented the IHY Secretariat. Representatives of many of the observatory networks were present during the workshop. Professors Yumoto and Chilingarian received commendations from UNCOUPOS for deploying the large networks of IHY instruments.

The main theme of the workshop was "First Results from the International Heliophysical Year 2007". First results from the IHY networks were presented along with scientific developments in various countries. In total, 70 Oral presentations and 92 Poster presentations were made.

The following were the main scientific sessions:

Opening session, Climate, Heliobiology, Solar Physics (3), Heliosphere, Cosmic Rays, IMF, Magnetospheres, Ionosphere, High and Middle Atmosphere (2), Access to data of the Sun-Earth system, Instruments and Networks (4), Participation of nations in IHY and BSS, and Closing session.
It was decided that the papers presented at the workshop will be published in the Sun and Geosphere Journal.
