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. Author
