Some Features of the Evolution of the Magnetic Complex of Activity Including AO NOAA 11944 and NOAA 11946, During Its Passage Across the Solar Disk

The evolution of properties of the magnetic activity complex (MAC) during its passage across the solar disk on (03-12).01.2014 was analyzed. This MAC comprises two active regions (ARs) magnetically coupled by the equator, that are located in different solar hemispheres: AR NOAA 11944 in the Southern Hemisphere and NOAA 11946 in the Northern Hemisphere. Time dependences of total unsigned magnetic fluxes of all spots, including pores, and specifically for each polarity were plotted for each AR. The variation of total unsigned magnetic flux F(t) for all MAC sunspots was examined with respect to the variation of total area of the corresponding sunspots S(t). In all cases, the magnetic flux increases non-monotonically, reaches its maximum, and decreases afterwards. We found differences in the pattern of changes in F(t) and S(t) during the period 10.01-12.01, which are related to the characteristics of radiation bursts in the hard X-ray range and solar flares in soft X-ray range. No halo-type coronal mass ejections were detected in the MAC during the entire observation period, and relatively few limb CMEs were detected when the MAC was close to limbs.
