The space missions Yohkoh, SOHO and TRACE, together with complementary ground-based instrumentation, have given us a several results on the Sun. This book presents the results in an organised, tutorial fashion: from the deep solar interior to the extended corona, with an emphasis on the diagnostic interpretation of the solar activity phenomena.

The space missions Yohkoh, SOHO and TRACE, together with complementary ground-based instrumentation, have in recent years given us a wealth of new results on the Sun, which are not readily available or digestible for the non-specialist. They are presented here in an organised, tutorial fashion by leading astrophysicists who gathered to observe the total eclipse of 11 August 1999 in Bucharest. Subjects covered range from the deep solar interior to the extended corona, with an emphasis on the diagnostic and on the physical interpretation of the spectacular phenomena represented by solar activity. It is useful for graduate students. Senior scientists will appreciate the comprehensive update of solar physics. Amateur astronomers having an adequate knowledge of physics will also enjoy the book.
