Passage: Above the chromosphere, in a thin (about 200 km) transition region, the temperature rises rapidly from around 20,000 K in the upper chromosphere to coronal temperatures closer to 1,000,000 K. Kuwedzera kwetembiricha kunofambiswa ne ionization izere ye helium munharaunda yekuchinja, iyo inoderedza zvakanyanya kutonhora kwemwaranzi yeplasma. Nzvimbo yekuchinja haiitike pakukwirira kwakanyatsotsanangurwa. Panzvimbo pezvo, inoumba mhando ye nimbus yakatenderedza zvimiro zvechromospheric senge spicules uye tambo, uye iri mukuenderera, kusagadzikana kufamba. Nzvimbo yekuchinja haina kuoneka zviri nyore kubva pamusoro pePasi, asi inocherechedzwa zviri nyore kubva muchadenga nemidziyo inonzwisisika kune yakanyanya ultraviolet chikamu cheiyo spectrum. Mhepo ndiyo inotevera corona yezuva.
