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.

The present state of our knowledge concerning the formation of positive and negative ions in the earth's normal ionosphere is reviewed. The main process by which positive ions and electrons are formed in the ionosphere is photoionization of neutral constituents by solar vacuum ultraviolet radiation. Negative ions are formed primarily by direct attachment of electrons to certain neutral constituents. Existing values of the cross sections and rate coefficients of these processes are presented and gaps in the present knowledge are discussed.
