This study reveals correlations between the motion of pores and the maximum magnetic pressure difference at their opposite edges, but no causal relationship between the two is found.
An analysis of two active regions shows that differently evolving ARs may produce major eruptive flares even when, in addition to the accumulation of significant free magnetic energy budgets, they accumulate large amounts of both left- and right-handed helicity without a strong dominance of one handedness over the other.
Magnetic flux loss from the solar interior due to flux emergence explains why all solar cycles decline in the same way.
The CGEM team identified and corrected two artifacts that had affected the electric field calculation for a small number of active regions.
