Comparison of Magnetic Properties and Shadow Area of Leading and Trailing Spots with Different Asymmetries

Abstract

The magnetic properties of the shadow of magnetic-related leading and trailing spots (those connected by forces lines of magnetic field, which are calculated from a field in potential approximation) are studied in this work. The correlations are established between individual characteristics of the field in the spot shadow and these characteristics from the shadow area S for spot pairs, for which the minimum angle between the measured vector of magnetic induction B in the shadow of the leading (L) spot and positive normal to the solar surface is lower than in the trailing (F) spot (α_min-L < α_min-F) and, vice versa, when α_min-L > α_min-F. It is shown that the α_min-L(S_L), α_min-F(S_F), B_max-L(S_L) and B_max-F(S_F) correlations are similar behaviorally and quantitatively for two groups of spots with different asymmetries of a magnetically connected field (B_{max-L, F} is the maximum of magnetic induction in the shadow of leading and trailing spots). The correlation between the average angles within the spot shadow 〈α_{L, F}〉 and the area of the spot shadow S_{L, F} and between the average value of magnetic induction in the spot shadow 〈B_{L, F}〉 differ in two cases. In most studied spot pairs, the leading spot is closer to the dividing line of polarity between the spots rather than the trailing one.
