- Аннотация: Spectroscopical observations of several prominences in the MgI lines were carried outfrom 2014 to 2017. These lines from visible part of the solar spectrum play an importantdiagnostic role, complementing the UV Mg II resonance lines regularly observed by theIRIS satellite. We found that a rather weak Mg I emission, e.g., in the 5172.6 A linecorrelates well with the presence of extended bright areas on the solar disk observed inthe 1600 A SDO / AIA band. However, in many cases the radiation in the 5172.6 Aline is very low, even not detectable, although a bright prominence above the limb orare on the solar disc were observed. To explain this phenomenon, we have calculatedspectra of optically thin plasma using Cloudy code and found that observed ratio ofoptical lines and UV continuum is possible and the presence of heel processes stimulatesluminescence in Mg I and 1600 A lines.
