Flare-productive active regions
Shin Toriumi, Haimin Wang
Strong solar flares and coronal mass ejections, here defined not only as the bursts of electromagnetic radiation but as the entire process in which magnetic energy is released thro…
Strong Transverse Photosphere Magnetic Fields and Twist in Light Bridge Dividing Delta Sunspot of Active Region 12673
Haimin Wang, Vasyl Yurchyshyn, Chang Liu +3
Solar Active Region (AR) 12673 is the most flare productive AR in the solar cycle 24. It produced four X-class flares including the X9.3 flare on 06 September 2017 and the X8.2 lim…
Iwahashi Zenbei's Sunspot Drawings in 1793 in Japan
Hisashi Hayakawa, Kiyomi Iwahashi, Harufumi Tamazawa +2
Three Japanese sunspot drawings associated with Iwahashi Zenbei (1756-1811) are shown here from contemporary manuscripts and woodprint documents with the relevant texts. We reveale…
The direct relation between the duration of magnetic reconnection and the evolution of GOES light curves in solar flares
Jeffrey W Reep, Shin Toriumi
GOES soft X-ray light curves are used to measure the timing and duration of solar flare emission. The timing and duration of the magnetic reconnection and subsequent energy release…
Numerical Simulations of Flare-productive Active Regions: delta-sunspots, Sheared Polarity Inversion Lines, Energy Storage, and Predictions
Shin Toriumi, Shinsuke Takasao
Solar active regions (ARs) that produce strong flares and coronal mass ejections (CMEs) are known to have a relatively high non-potentiality and are characterized by delta-sunspots…
