THE SEQUENCE OF APPEARANCE OF LINES OF DIFFERENT ELEMENTS IN FLARES.

Abstract

The sequence of appearance of lines of different elements in flares is studied. It is found that the brightness maximum of flares in lines of rare earths appears a few minutes later (about 5 minutes) than the maximum in lines of such metals as Mg, Fe, Al. This effect can be explained by the emission of a flare in the upper chromospheric layers reaching, with some retardation, the lower chromosphere, where the rare earths are mainly localized.
