Magnetic reconnection between small-scale loops observed with the New Vacuum Solar Telescope
Shuhong Yang, Jun Zhang, Yongyuan Xiang
Using the high tempo-spatial resolution H images observed with the New Vacuum Solar Telescope, we report the solid observational evidence of magnetic reconnection between two se…
Direct Observations of Tether-cutting Reconnection During a Major Solar Event From 2014 February 24 to 25
Huadong Chen, Jun Zhang, Xin Cheng +3
Using the multi-wavelength data from Atmospheric Imaging Assembly on board the Solar Dynamic Observatory, we investigated two successive solar flares, a C5.1 confined flare and an…
Conversion from mutual helicity to self-helicity observed with IRIS
Leping Li, Hardi Peter, Feng Chen +1
Context. In the upper atmosphere of the Sun observations show convincing evidence for crossing and twisted structures, which are interpreted as mutual helicity and self-helicity. A…
Initiation and Eruption Process of Magnetic Flux Rope from Solar Active Region NOAA 11719 to Earth Directed-CME
P. Vemareddy, J. Zhang
An eruption event launched from solar active region (AR) NOAA 11719 is investigated based on coronal EUV observations and photospheric magnetic field measurements obtained from Sol…
Fine Structures and Overlying Loops of Confined Solar Flares
Shuhong Yang, Jun Zhang, Yongyuan Xiang
Using the H observations from the New Vacuum Solar Telescope at Fuxian Solar Observatory, we focus on the fine structures of three confined flares and the issue why all the thre…
Slipping Magnetic Reconnection Triggering a Solar Eruption of a Triangle-flag Flux Rope
Ting Li, Jun Zhang
We firstly report the simultaneous activities of a slipping motion of flare loops and a slipping eruption of a flux rope in 131 Å and 94 Å channels on 2014 February 02. The east ho…
