10 Solar activity

Abstract

The time period covered by this report (1 July 1993 - 30 June 1996) has seen the flawless launch and operation of SOHO, the full development of the Global Oscillation Network (GONG) and other seismology networks, a continued successful operation of YOHKOH, the southern and northern passages of ULYSSES, as well as significant advances in high resolution solar observing techniques.The topics of the present report have been chosen with the aim to maintain a long-term balance in the coverage of activities of the three Commissions, ranging from instrumentation and observing techniques to the most important work and new scientific results from studies of the Sun and Heliosphere. It is our intention to provide critical reviews of the field, which may also be useful for the non-specialist reader.
