Sunspots: Theory and Observations

This volume contains the invited papers presented at the NATO Advanced Research Workshop on the Theory of Sunspots, held in Cambridge, England, 22-27 September 1991. The idea of holding this Workshop first arose during the Solar Optical Telescope work­ shop on Theoretical Problems in High-Resolution...
