Since its launch in 1991, the Yohkoh satellite has been returning unprecedented observations of solar flares and the dynamic solar corona. This book is a collection of papers presented at a meeting held in: Yoyogi, Tokyo, on the occasion of Yohkoh’s fifth anniversary of operation. The papers constitute a summary of observations and results over the five years, including contributions based on data from Yohkoh’s hard and soft X-ray telescopes and its spectrometer experiments. The five years of data, covering approximately one-half of a solar cycle, reveal a fresh perspective on solar science, with a new picture of solar flares and the active Sun emerging. Also, for the first time there are extensive results from Yohkoh observations of the Sun during the solar minimum period.

This wide-ranging volume will be of interest to workers in solar physics and X-ray astronomy. It also contains material appropriate for supplemental reading for graduate students in solar physics.
