Plasmoids, Flows, and Jets during Magnetic Reconnection in a Failed Solar Eruption

Abstract We report a detailed analysis of failed eruption and flare in active region 12018 on 2014 April 3 using multiwavelength observations from the Solar Dynamics Observatory/Atmospheric Imaging Assembly, IRIS, STEREO, Hinode/Solar Optical Telescope. At least four jets were observed to emanate cusp this small (large bright point) with null-point topology during 2 hr prior slow rise filament. During filament multiple plasma blobs seen, most likely formed current sheet near cusp. The subsequent eruption, which was outside IRIS field view, accompanied by but remained confined. explosive reconnection phase, additional appeared repetitively moved bidirectionally within flaring below erupting kinked, rotated, underwent leg–leg as it rose, yet produce coronal mass ejection. Tiny jet-like features fan loops detected rise/preflare phase. interpret them signatures between ambient magnetic plasmoids leaving streaming along loops. contrast our interpretation these tiny jets, occur large-scale context local nanoflare-heating scenario proposed Antolin et al.
