چکیده انگلیسی
In this work we describe dynamical features of brightenings along coronal loops using a method derived in a previous paper. We register the behavior of space and time intensity variations along a compound of coronal magnetic tubes imaged by the Transition Region and Coronal Explorer (TRACE) in the well known coronal line at 17.1Â nm. The studied loops were observed in the south-west limb on October 1st, 2001. We determine a coherent behavior of the intensity along neighboring magnetic tubes. During a first time interval we register a downflow with a brightening average speed of â111kms-1 and during a second time interval we detect an upward displacement of the brightening with an average speed of â50kms-1.
