Interaction between network and intranetwork magnetic fields

Using high-resolution observations of deep magnetograms and Hα 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.
