On the Brightening Propagation of Post-Flare Loops Observed by TRACE
Leping Li, Jun Zhang
Examining flare data observed by TRACE satellite from May 1998 to December 2006, we choose 190 (151 M-class and 39 X-class) flare events which display post-flare loops (PFLs), obse…
Determination of Topology Skeleton of Magnetic Fields in a Solar Active Region
Hui Zhao, Jing-Xiu Wang, Jun Zhang +2
The knowledge of magnetic topology is the key to understand magnetic energy release in astrophysics. Based on observed vector magnetograms, we have determined threedimensional (3D)…
The velocity structure of moving magnetic feature pairs around sunspots: support for the U-loop model
Jun Zhang, S. K. Solanki, J. Woch +1
Using data recorded by the Michelson Doppler Imager (MDI) instrument on the Solar and Heliospheric Observatory (SOHO), we have traced 123 pairs of opposite magnetic polarity moving…
Interaction between a fast rotating sunspot and ephemeral regions as the origin of the major solar event on 2006 December 13
Jun Zhang, Leping Li, Qiao Song
The major solar event on 2006 December 13 is characterized by the approximately simultaneous occurrence of a heap of hot ejecta, a great two-ribbon flare and an extended Earth-dire…
Discovery of inward moving magnetic enhancements in sunspot penumbrae
Jun Zhang, S. Solanki, J. Woch
Sunspot penumbrae show a fine structure in continuum intensity that displays considerable dynamics. The magnetic field, in contrast, although also highly structured, has appeared t…
