Intrusion of Magnetic Peninsula toward the Neighboring Opposite-polarity Region That Triggers the Largest Solar Flare in Solar Cycle 24
Yumi Bamba et al 2020 ApJ 894 29
Analysis of multiple observational datasets for the largest X9.3 solar flare in solar cycle 24 shows that it may have been triggered by the intrusion of a major negative-polarity region into an opposite-polarity region.
