Objectives:

• Coordinate and consolidate European research activities in the field of local helioseismology; exchange knowledge and share experiences.
• Identify areas for which common actions are desirable.
• Promote the exchange of data for tests, comparisons, and analysis.
• Coordinate the process of developing common software tools.
• Facilitate the preparation for SDO and Solar Orbiter missions.
