THE ASYMMETRICAL EFFECT OF THE FLARE POSITION ON GEOMAGNETIC ACTIVITY,
Abstract
Flares of importance > or = II(+) are grouped according to their heliographic position and magnetic condition of the active regions. Using the 'superposed-epoch method', the mean daily frequency for K sub p > or = 6 under different conditions is calculated. It is found that for the magnetic group beta gamma + gamma + beta sub f, solar flares in the northern hemisphere produce a stronger corpuscular effect than those in the southern, but for the flares in the beta sub p + beta regions, no such hemispheric asymmetry is found. Also, in the southern hemisphere, western flares have a stronger effect than the central and eastern ones, but in the northern hemisphere, only those in the beta sub p + beta regions have such an east-west asymmetry. These asymmetrical relations appeared in all of the last three sunspot cycles and were especially conspicuous during the equinoxes. (Author)
