Abstract : A brief history of the Sacramento Peak Flare Patrol is given as background for discussion of some statistical properties of 4227 flares. East-west asymmetry of flares exists, but is not statistically significant. Flare distribution in heliocentric longitude is discussed, and criticized as an indication of flare geometry. Area frequency functions in distinct radial zonesARE APPLIED TO DETERMINE FORESHORTENING CORRECTION FACTORS. Flare growth curves, defined by times of start, maximum, and end, are found to correlate well with maximum area (importance), but not with position on the disk, duration, or estimated intensity.
