This paper presents a study of 9 “spotless” flares of H-alpha importance 1 or more which occurred in the years 1981-1990. The flares occurred in positions where no active region has been reported. All the flares were found to occur in evident and well-localized plages, large and diffusive plages as well as in regions where no plage was observed. Only one of all the flares studied in the paper was reported to be accompanied by the filament activity.
