Magnetic Helicity Flux across Solar Active Region Photospheres. II. Association of Hemispheric Sign Preference with Flaring Activity during Solar Cycle 24

In our earlier study of this series (Park et al. 2020, Paper I), we examined the hemispheric sign preference (HSP) magnetic helicity flux $dH/dt$ across photospheric surfaces 4802 samples 1105 unique active regions (ARs) observed during solar cycle 24. Here, investigate any association HSP, expressed as a degree compliance, with flaring activity, analyzing same set estimates used in I. The AR under investigation are assigned to heliographic (HRs) defined Carrington longitude-latitude plane grid spacing 45$^\circ$ longitude and 15$^\circ$ latitude. For each HRs, calculate HSP compliance average soft X-ray flare index. strongest activity is found be one distinctive HR an extremely low 41% compared mean standard deviation 62% 7%, respectively, over all HRs. This sole shows anti-HSP (i.e., less than 50%) includes highly flare-productive NOAA 12673, however not uniquely responsible for HR's HSP. We also find that HRs highest located southern hemisphere, they tend have lower degrees compliance. These findings point presence localized convection zone enhanced turbulence, imparting greater complexity higher rate some rising tubes.
