An Analysis of the Formation of Interconnecting Loops
Chen, Jie; Deng, Yuanyong; Zhang, Yin +2 more
Fifty interconnecting loops (ILs) that are induced by new-born active regions are investigated. The formation period of four ILs including two same-hemisphere interconnecting loops (HILs) and two transequatorial loops (TLs) are analyzed. The magnetic flux related with these loops is studied. Considering the active region pairs related with the IL …
Simultaneous Observations of the Chromosphere with TRACE and SUMER
Dammasch, Ingolf E.; Pasachoff, Jay M.; Sterling, Alphonse C. +1 more
Using mainly the 1600 Å continuum channel and also the 1216 Å Lyman-α channel (which includes some UV continuum and C IV emission) aboard the TRACE satellite, we observed the complete lifetime of a transient, bright chromospheric loop. Simultaneous observations with the SUMER instrument aboard the SOHO spacecraft revealed interesting material velo…
