Abstract

Previously published results of EUV explosive events and electron density enhancements in the solar transition region are revised. An attempt has been made to correlate both observational phenomena, and to associate the observed density enhancements to magnetic reconnection sites. The corresponding local magnetic field strength in these sites is estimated. These values are of the same order as previously measured in photospheric cancelling flux regions.

Key words: Sun: atmosphere – Sun: magnetic fields – Sun: particle emission – Sun: transition region – Sun: UV radiation
