21. Three-ribbon Solar Flares: What Do They Imply for the 3D Magnetic Field Structure?

Contributed by Haimin Wang. Posted on June 27, 2014

Combining the outstanding capability of HMI/SDO  and NST/BBSO,  we studied two rarely observed three-ribbon flares. The flaring site is characterized with an intriguing &#8220fish-bone&#8221-like morphology. These results are discussed in favor of reconnection along the coronal null-line.
