Interaction between network and intranetwork magnetic fields

Using high-resolution observations of deep magnetograms and H filtergrams obtained at Big Bear Solar Observatory during 17–24 October 1997, we have studied the interaction of intranetwork and network elements. The relationship between small-scale magnetic fields and active phenomena is investigated. Most of the small-scale active phenomena are triggered by the interaction either between intranetwork and network magnetic elements or among several network elements. The energy released due to the interaction of intranetwork–network elements and network–network elements is large enough to heat the corona.
