This volume presents the papers from a major international conference aimed at cross-linking research in the fields of solar and stellar activity. The Yohkoh satellite, with its views of solar coronal structures seen via their X-ray emission, provided the immediate motivation for the conference. How do these solar structures transcribe into their stellar counterparts? What insights can the more extreme stellar activity provide to guide the analysis of solar data? Longer-term variation associated with the 11-year solar cycle can also be seen clearly in the data presented. The new data strongly supports many earlier interpretations of such magnetodynamic activity, but also provide some perplexing mismatches now stimulating new theoretical work.
